Welcome to 4shared SOAP API documentation!

Dear developer!

We are glad to introduce you official 4shared API Program. With the 4shared API, you can get started developing your application for Mobile Phones (iPhone, Android, Symbian, Blackberry, Windows mobile), Windows, Mac, iPad, and Linux today.

You may easily use more than 50 API functions to perform any actions with 4shared like - access web account, upload\download files, search files, create and delete folders, etc.

4shared API is totaly free! All required samples you may find at 4shared API documentation. Any questions regarding 4shared developer program you may discuss at our forum.

Every month we will pick best app with 4shared API (the more inserted key 4shared functions, the better) and award developer for $5,000! We pay $5,000/month for best app.

Sources

4shared Project at google code.google.com

WSDL can be obtained from here or please check here for more secure SOAPing.

You can browse java sources from mercurial repositories at http://code.google.com/p/4shared-api/source/browse/. Or use hg clone https://4shared-api.googlecode.com/hg/ 4shared-api to get local copy of sources.

Quick start guide

To start working with 4shared SOAP API you should have a copy of mercurial for your favorite OS, Java SDK, ant building system. Some Java IDE is also recomended.

1. Get sources from google.code.com:

 hg clone https://4shared-api.googlecode.com/hg/ 4shared-api

2. Go to created folder and build project:

ant

3. Try to use some of provided examples:

 cd dist/demo
 ./signup <username> <password>
 ./createfolder <username> <password> <foldername>
 ./upload <username> <password> <path to file>
 ./browse <login> <password>

4. Learn how this demos have been written. All demo sources are situated in demo/com/pmstation/shared/soap/demo

5. Write your own fresh and brilliant application

6. Important! You must include the following into the app:

Check the simple example:

let's have the user app_name_test have password 1,

where app_name - is the name of your application.

user enters his credentials as:

login: "app_name_test "

password: "1"

You should silently add designator for your to user provided password.

So, you will send:

login: "app_name_test "

password: "!!!app_name!!:1"

for any function, which needs password.

iOS

Every application in iOS can use 4shared service. The client can interact with 4shared server via SOAP protocol, by means of calling up 4shared API functions. These functions may be used to request for the content of your account, get the necessary links to files, and edit the file structure and the directory properties on the server. The full description of the api is provided here (link to http://help.4shared.com/index.php/SOAP_API). The SOAP-protocol may be checked here (link to http://en.wikipedia.org/wiki/SOAP).

To call up 4shared api-function, it’s necessary to send the XML-message to server http://api.4shared.com/jax2/DesktopApp SOAP.

The common template for the message is the following:

|<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" <br>xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<soapenv:Body>

		<function xmlns="http://api.soap.shared.pmstation.com/">
			<arg0 xmlns="">login</arg0>
			<arg1 xmlns="">password</arg1>
			<arg2 xmlns="">arg1</arg2>
			...
		</function>
	</soapenv:Body>
</soapenv:Envelope>" ,where “function” is the name of the called function.

Having indicated the function, one should enlist its arguments. There’re only 2 arguments in almost all 4shared api-functions – these are login and password.

In response to the call, 4shared server will return the results of the function, the SOAP-message in XML-format:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
	<S:Body>
		<ns2:functionResponse xmlns:ns2="http://api.soap.shared.pmstation.com/">
			<return>
				result
			</return>
		</ns2: functionResponse>
	</S:Body>
</S:Envelope> , where “result” is the result of calling up the “function”.

As an example, we need to get the content of the directory. To do this, we need to call the function “getItems” (link to http://help.4shared.com/index.php/SOAP_API#getItems).

Its first 2 arguments are, as usual, login and password. The 3rd one is the ID of the requested directory.

The body of the relative SOAP-message will be as follows:

<getItems xmlns="http://api.soap.shared.pmstation.com/">
	<arg0 xmlns="">username@server.com</arg0>
	<arg1 xmlns="">*********</arg1>
	<arg2 xmlns="">123456789</arg2>
</getItems>

In response, 4shared server will return the array with the elements of directory:

<item>
	<date>(date of file creation)</date>
	<directory>(true – if file is a directory, otherwise - false)</directory>
	<downloadCount>(the number of file downloads)</downloadCount>
	<downloadLink>(link for the file-download from 4shared-server)</downloadLink>
	<id>(file ID)</id>
	<md5>(md5-hash)</md5>
	<name>(name)</name>
	<parentId>(parent directory ID)</parentId>
	<size>(size)</size>
	…
</item>

Let’s consider the example of the simple application, which allows the user to browse the content of his/her account.

The 1st thing, which should be done, when starting the program, is to authorize (login) on 4shared server by means of calling up the function “login” (link to http://help.4shared.com/index.php/SOAP_API#login ).

If authorization is passed successfully, the next step will be the request for the root account directory by means of calling up the function “getRoot” (link to http://help.4shared.com/index.php/SOAP_API#getRoot). The calling result will be the structure “item”, described above.

To store received information, I’ve created subclass File:

@interface File : NSObject
{
	NSUInteger _id;
	NSUInteger _parentId;
	NSString *_name;
	NSUInteger _size;
	NSString *_link;
	BOOL _dir;
    
	NSArray *_content;
}

…

@end

Now that we have the root directory ID, we can use the function “getItems”, to get its content, and then the content of any subdirectory.

To create the XML-formatted message and the parsing of received result, it’s possible to use any XML – parser. In the demo-sample, I’ve used GDataXML-parser from Google Data APIs Objective-C Client Library http://code.google.com/p/gdata-objectivec-client/).

The function to generate the message may be as follows:

+ (NSURLRequest*)soapRequestWithFunction:(NSString*)function andParams:(NSArray*)params
{
   	GDataXMLElement *xmlFunction = [GDataXMLNode elementWithName:function];
	GDataXMLNode *xmlNS = [GDataXMLNode namespaceWithName:nil stringValue:@"http://api.soap.shared.pmstation.com/"];
	[xmlFunction addNamespace:xmlNS];
	
	for (NSUInteger i = 0; i < [params count]; i++)
	{
		NSString *elementName = [NSString stringWithFormat:@"arg%lu", i];
		GDataXMLElement *arg = [GDataXMLNode elementWithName:elementName];
		NSString *param = (NSString*)[params objectAtIndex:i];
		[arg setStringValue:(NSString*) param];
		GDataXMLNode *attrib = [GDataXMLNode attributeWithName:@"xmlns" stringValue:@""];
		[arg addAttribute:attrib];
		[xmlFunction addChild:arg];
	}
    
	GDataXMLElement *body = [GDataXMLNode elementWithName:@"soapenv:Body"];
	[body addChild:xmlFunction];
	
	GDataXMLElement *soapEnvelope = [GDataXMLNode elementWithName:@"soapenv:Envelope"];
	GDataXMLNode *soapNS1 = [GDataXMLNode namespaceWithName:@"soapenv" stringValue:@"http://schemas.xmlsoap.org/soap/envelope/"];
	GDataXMLNode *soapNS2 = [GDataXMLNode namespaceWithName:@"xsd" stringValue:@"http://www.w3.org/2001/XMLSchema"];
	GDataXMLNode *soapNS3 = [GDataXMLNode namespaceWithName:@"xsi" stringValue:@"http://www.w3.org/2001/XMLSchema-instance"];
	[soapEnvelope setNamespaces:[NSArray arrayWithObjects:soapNS1, soapNS2, soapNS3, nil]];
	[soapEnvelope addChild:body];
	
	GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithRootElement:soapEnvelope];
	[doc setVersion:@"1.0"];
	[doc setCharacterEncoding:@"UTF-8"];
	NSData *data = [doc XMLData];
	[doc release];
	NSString *dataLen = [NSString stringWithFormat:@"%lu", [data length]];
	
	NSURL *url = [NSURL URLWithString:@"http://api.4shared.com/jax2/DesktopApp"];
	NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
	[request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
	[request addValue:@"" forHTTPHeaderField:@"SOAPAction"];
	[request addValue:dataLen forHTTPHeaderField:@"Content-Length"];
	[request setHTTPMethod:@"POST"];
	[request setHTTPBody: data];
	
	return request;
}

The content of the directory is shown in the table (class FilesViewController). I show its name and size in the cell, related to the file accordingly:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
	…
	cell.accessoryType = file.isDir ? UITableViewCellAccessoryDisclosureIndicator : UITableViewCellAccessoryNone;
	cell.imageView.image = file.isDir ? [UIImage imageNamed:@"dir.png"] : nil;
	cell.textLabel.text = file.name;
	cell.detailTextLabel.text = file.isFile ? [NSString stringWithFormat:@"%.2f Kb", (CGFloat) file.size / 1024.0] : nil;
	…
}

All content is opened via tap in the cell with directory. The page with the following link is opened in the browser via tap on the file:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
	…
	if (file.isDir)
	{
		FilesViewController *fvc = [[FilesViewController alloc] initWithFile:file];
	        [self.navigationController pushViewController:fvc animated:YES];
        	[fvc release];
	}
	else
	{
        	[[UIApplication sharedApplication] openURL:[NSURL URLWithString:file.link]];
	}
	…
}

The demo-sample can be downloaded here (http://dc243.4shared.com/download/ecV5Tw4I/ios_samples.zip).

To start the sample application, enter demo-Prefix.pch in the file, enter your login and password from the site 4shared (macros LOGIN and PASSWORD).

Symbian (QT)

Every application can interact with 4shared server via SOAP protocol, by means of calling up 4shared API functions.

These functions may be used to request for the content of your account, get the necessary links to files, and edit the file structure and the directory properties on the server.

The full description of the api is provided here (link to http://help.4shared.com/index.php/SOAP_API).

The SOAP-protocol may be checked here (link to http://en.wikipedia.org/wiki/SOAP).

As an SDK for creating applications for mobile devices, let’s take "Nokia Qt SDK 1.0", which can be got here (http://www.forum.nokia.com/Develop/Qt/). This package also includes IDE "Qt Creator", which we will use.

In the beginning, let’s create the new project with type “Mobile application Qt” and name it 4shared. In the visual editor we’ll add “List widget” in the main window, which will include the elements of the root catalogue, downloaded from 4shared server. In the class MainWindow constructor, in a line

- setCentralWidget(ui->listWidget); - stretch listWidget to the full screen.

To work with SOAP protocol in a more convenient way, we’ll take initial codes from the library QtSOAP and insert them into the project, as this library isn’t included into mobile version.

In addition to that, in order to make the application work with network in Symbian devices, it’s necessary to add the following line in the file 4shared.pro in the part, devoted to the specific Symbian settings:

-
Symbian {
	...
	TARGET.CAPABILITY += NetworkServices
	...
}
-

Then, we’ll add and initialize members in class MainWindow':

-
class MainWindow : public QMainWindow
{
	...
    QNetworkAccessManager nam;
    QtSoapHttpTransport http;
	...
};

MainWindow::MainWindow(QWidget *parent) :
	...
    nam(this),
    http(this),
	...
{
	...
    connect(&http, SIGNAL(responseReady()), SLOT(getResponse()));

    http.setNetworkAccessManager(&nam);
    http.setAction("");
    http.setHost("api.4shared.com", 80);
	...
}
-
,which realize (implement) the transfer of our future requests.

The slot getResponse() will be invoked, when the answers to our requests are received.

To download the list of files and subdirectories of the root directory, it’s necessary to perform 3 requests in series:

1. isExistsLoginPassword - authentication

2. getRoot – receipt of information about the root directory

3. getItems – receipt of the list of elements in the defined directory (in our case – root directory )

-
class MainWindow : public QMainWindow
{
	...
private slots:
    void getResponse();

private:
    QtSoapMessage initStdSoapMessage(const QString &methodName);

    void authorize();
    void authorizeHandler(const QtSoapType &res);

    void getRoot();
    void getRootHandler(const QtSoapType &res);

    void getItems(long id);
    void getItemsHandler(const QtSoapType &res);

    enum Operation {unknown, authorize_op, getRoot_op, getItems_op};

private:

    QString login, password;

    long rootId;
};

void MainWindow::getResponse()
{
    Operation op = operation;
    operation = unknown;

    // Get the response, check for error.
    const QtSoapMessage &resp = http.getResponse();
    if(resp.isFault()) {
        QMessageBox::warning(NULL, "Warning", "SOAP: query failed (" + resp.faultString().value().toString() + ")");
        return;
    }

    // Extract the return value from this method response, check for errors.
    const QtSoapType &res = resp.returnValue();
    if(!res.isValid()) {
        QMessageBox::warning(NULL, "Warning", "SOAP: invalid return value");
        return;
    }

    switch(op)
    {
    case authorize_op:
        authorizeHandler(res);
        break;

        break;
    case unknown:
        break;
    }
}

QtSoapMessage MainWindow::initStdSoapMessage(const QString &methodName)
{
    QtSoapMessage request;
    request.setMethod(QtSoapQName(methodName, "http://api.soap.shared.pmstation.com/"));
    request.addMethodArgument("arg0", "", login);
    request.addMethodArgument("arg1", "", password);
    return request;
}

void MainWindow::authorize()
{
    QtSoapMessage request = initStdSoapMessage("isExistsLoginPassword");
    operation = authorize_op;
    http.submitRequest(request, "/jax2/DesktopApp");
}

{
    bool auth = res.value().toBool();
    if(auth)
    {
       // QMessageBox::information(NULL, "Authorization", "Authorized");
        getRoot();
    }
    else
        QMessageBox::warning(NULL, "Warning", "Invalid user name or password");
}

void MainWindow::getRoot()
{
    QtSoapMessage request = initStdSoapMessage("getRoot");
    operation = getRoot_op;
    http.submitRequest(request, "/jax2/DesktopApp");
}

void MainWindow::getRootHandler(const QtSoapType &res)
{
    rootId = res["id"].toInt();
    getItems(rootId);
}

void MainWindow::getItems(long id)
{
    QtSoapMessage request = initStdSoapMessage("getItems");
    request.addMethodArgument("arg2", "", id);
    operation = getItems_op;
    http.submitRequest(request, "/jax2/DesktopApp");
}

void MainWindow::getItemsHandler(const QtSoapType &res)
{
    for(int i=0; i<res.count(); i++)
    {
        const QtSoapType &item = res[i];

        if(item["removed"].toBool())
            continue;

        QString name;
        if(item["directory"].toBool())
            name = " <dir> ";
        name += item["name"].toString();

        QListWidgetItem *itm = new QListWidgetItem(name);
        itm->setSizeHint(QSize(0, 50));
        ui->listWidget->addItem(itm);
    }
}

Demo-sample can be downloaded here (http://dc243.4shared.com/download/bFbwuFVS/symbian_Qt_example.zip).

To start the sample application, insert your login and password from 4shared in the file MainWindow.cpp (variable login and password).

Android

1. 4shared API.

Service 4shared is a usual web-service, WSDL description of which is here: https://api.4shared.com/jax2/DesktopApp?wsdl.

You can read more about web-services and WSDL' here: http://ru.wikipedia.org/wiki/%D0%92%D0%B5%D0%B1-%D1%81%D0%BB%D1%83%D0%B6%D0%B1%D0%B0, http://ru.wikipedia.org/wiki/WSDL.

Short description of API functions can found here: http://help.4shared.com/index.php/SOAP_API.

To work with SOAP API, you can use direct SOAP-calling, but it’s more convenient to use another library for request parsing. For instance, you can use free library: (http://code.google.com/p/ksoap2-android/).

2. Tools for Development.

Development of applications for Android is possible on any platform, which allows Andrid SDK setup. System requirements can be checked here: http://developer.android.com/sdk/requirements.html.

You can download Android SDK here: http://developer.android.com/sdk/index.html, setup instructions are available here: http://developer.android.com/sdk/installing.html.

The recommended environment for development is Eclipse (http://www.eclipse.org/downloads/) with the plugin for Android (http://developer.android.com/sdk/eclipse-adt.html). Any device with OS Android, or an emulator of the device, included into Android SDK, is suitable for starting the developed application.

Detailed instruction for beginners in app development can be found here: http://developer.android.com/guide/developing/index.html.

3. Step-by-Step Instruction.

Resource http://developer.android.com comprises all necessary information for developers.

The most essential (fundamental) notions are described in the article: http://developer.android.com/guide/topics/fundamentals.html.

Step-by-step instruction of the simple app for 4shared is displayed below.

1) Install a Platform (http://developer.android.com/resources/tutorials/hello-world.html)

2) Create an AVD (http://developer.android.com/resources/tutorials/hello-world.html)

3) Create a New Android Project (http://developer.android.com/resources/tutorials/hello-world.html)

4) To insert changes, needed to make the minimum 4shared-application work

To link the ksoap2 library to the project, it’s necessary to create subcatalog libs in the catalogue Hello4shared and place jar-archive of this library there. Then, choose Project > Options in menu Eclipse, and after that select subsection Java Build Path and tab Libraries. Press the button Add JARs and display the path to the library.

With the help of menu File > New > Class, let’s create 2 subclasses: AccountItem, representing the user’s file or catalogue on 4shared server, and ForSharedService, with the help of which 4shared API remote methods are called up.

AccountItem is used to desereal data from the network and provides convenient methods to receive information about the file/catalogue, for example, getName() and getDownloadLink() return the filename and the download link accordingly.

    package com.example.hello4shared;

    import org.ksoap2.serialization.SoapPrimitive;

    /**
     * 4shared account item, representing a file or a directory description data.
     * Implementation includes network serialization functionality.
     */
    public class AccountItem {
	private long id;
	private String name;
	private boolean directory;

	public AccountItem() {
	}

	public long getId() {
	    return id;
	}

	public String getName() {
	    return name;
	}

	public boolean isDirectory() {
	    return directory;
	}

	public String toString() {
	    return directory ? "[" + name + "]" : name;
	}

	public void setProperty(String propName, Object value) {
	    if (value == null) {
		return;
	    }
	    if (value instanceof SoapPrimitive) {
		value = ((SoapPrimitive) value).toString();
	    }

	    if (propName.equals("id")) {
		if (value instanceof Long)
		    id = ((Long) value).longValue();
		else
		    id = Long.parseLong(value.toString());
	    }
	    if (propName.equals("directory")) {
		directory = convertBoolean(value);
	    }
	    else if (propName.equals("name")) {
		name = convertString(value);
	    }
	}

	private boolean convertBoolean(Object val) {
	    if (val == null)
		return false;

	    if (val.toString().toLowerCase().equals("true"))
		return true;
	    else
		return false;
	}

	private String convertString(Object str) {
	    if (!(str instanceof String))
		return null;

	    if (((String) str).equals("String{}"))
		return "";
	    else
		return (String) str;
	}
    }

ForSharedService is the interlayer for the convenient call of remote methods and hides the code of interaction with technology SOAP.

		   || string.toLowerCase().equals("string{}")
		   || string.toLowerCase().equals("anytype{}"));
	}
    }

The classes SoapObject, SoapSerializationEnvelope, AndroidHttpTransport – are included into the library ksoap2.

SoapObject, SoapSerializationEnvelope serve to parse soap-requests, whereas AndroidHttpTransport provides transport to call up the requests.

The call up of the function itself is realized by the method call (), of the class AndroidHttpTransport.

The service’s answer can be received by means of calling up the method getResponse() of the class SoapSerializationEnvelope.

The functions, transferred to the service, are defined by calling up the method addProperty of the class SoapObject as a pair “parameter name - value”.

Let’s create a window (activity) to display the list of user’s files and catalogues from 4shared server.

To do that, let’s create the new class (File > New > Class), derivative from ListActivity, in Eclipse environment, and call it AccountContents.

Let’s edit AccountContents.java, by redefining the method onCreate, called up by means of initializing the window (activity).


    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        // Use a ListAdapter that will map an array of account's root folder items to TextViews
        setListAdapter(new ArrayAdapter<AccountItem>(this,
                android.R.layout.simple_list_item_1, Hello4shared.rootContents));
    }

The class ArrayAdapter establishes accordance (correspondence) between the list elements of the user’s interface and the list of files and catalogues on 4shared server, which will be uploaded into the static variable rootContents of the class Hello4shared.

In the method onCreate of the main window (activity) of the application, the code of which is in the file Hello4shared.java, let’s create the elements of the user’s interface for insertion and transfer of the user’s name (login) and 4shared account password to the server.

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        // Prepare vertical linear layout
        LinearLayout mainLayout = new LinearLayout(this);
        mainLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
        mainLayout.setOrientation(LinearLayout.VERTICAL);
        
        // Create views
        TextView loginView = new TextView(this);
        loginView.setText("login:");
        TextView passwordView = new TextView(this);
        passwordView.setText("password:");
        
        final EditText loginEdit = new EditText(this);
        final EditText passwordEdit = new EditText(this);
        passwordEdit.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        
        Button loginButton = new Button(this);
        loginButton.setText("Submit");
        loginButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                String username = loginEdit.getText().toString();
                String password = passwordEdit.getText().toString();
                
                // If username and password entered correctly
                if (username.length() != 0 && password.length() != 0) {
                    // Start login procedure
                    login(username, password);
                }
            }
        });
        
        // Add views to layout
        mainLayout.addView(loginView);
        mainLayout.addView(loginEdit);
        mainLayout.addView(passwordView);
        mainLayout.addView(passwordEdit);
        mainLayout.addView(loginButton);
        
        // Set the layout as activity main layout
        setContentView(mainLayout);
    }

The handler of the press-button loginButton checks the properness of inserted data and, if succeeds, calls up the method login (), which starts the process of checking the user’s data on 4shared server, and also requests the list of files and catalogues of the account root catalogue.


    private void login(final String username, final String password) {
        mProgressDialog = ProgressDialog.show(this, "", "Please wait...", true);
        mProgressDialog.setCancelable(false);
        
        // We should call network calls on separate thread not to freeze the application UI
        new Thread() {
            @Override
            public void run() {
                // Create 4shared API local layer to call remote methods
                ForSharedService fss = new ForSharedService(username, password);
                try {
                    // Call login procedure
                    fss.login();
                    // Get account's root folder
                    AccountItem rootItem = fss.getRoot();
                    // Request contents of the root folder
                    rootContents = fss.getItems(rootItem.getId());
                    
                    // If we are here, this means all the operations succeeded
                    loginSucceeded();
                } catch (Exception e) {
                    // One of the operations has failed
                    loginFailed(e.getMessage());
                }
            }
        }.start();
    }

If the name (login) and password correspond to the account in 4shared database, and network connection has been set successfully, the call up of the method loginSucceeded () opens the window (en. activity), which displays the list of user’s files and catalogues, which has been stored into the static variable rootContents.


    private void loginSucceeded() {
        // Application UI transitions should be performed on the main thread
        mHandler.post(new Runnable() {
            @Override
            public void run() {
                mProgressDialog.dismiss();
                // Move to next activity to show list of account's root folder contents
                Intent intent = new Intent(Hello4shared.this, AccountContents.class);
                startActivity(intent);
            }
        });        
    }

The last thing, which should be changed is the configuration of the project in the file AndroidManifest.xml.

In the section <manifest> let’s request the permit to get the access of the application to the Internet:


                <uses-permission android:name="android.permission.INTERNET"></uses-permission>
       In the section <application>, let’s add the window(activity) AccountContents:
       		<activity android:name=".AccountContents"
		          android:label="@string/app_name">
		</activity>
       and define the portrait orientation for the window (activity) Hello4shared:
       	        android:configChanges="keyboardHidden|orientation"
                android:screenOrientation="portrait"

The full code of the demo-application is attached (http://dc243.4shared.com/download/l8R381Nw/androidsamples.zip).

1. Description of 4shared Service

Service 4shared is a usual web-service, WSDL description of which is here: https://api.4shared.com/jax2/DesktopApp?wsdl.

You can read more about web-services and WSDL here: http://ru.wikipedia.org/wiki/%D0%92%D0%B5%D0%B1-%D1%81%D0%BB%D1%83%D0%B6%D0%B1%D0%B0, http://ru.wikipedia.org/wiki/WSDL.

Short description of API functions can found here: http://help.4shared.com/index.php/SOAP_API.

To work with SOAP API, you can use direct SOAP-calling, but it’s more convenient to use another library for request parsing. For instance, you can use free library: (http://code.google.com/p/ksoap2-android/), which uses Java Microedition, working on Blackberry OS).

2. Demo Application

In the beginning, it’s necessary to create the new project in Eclipse (menu File-New-Project, in the list of project types – select Blackberry Project) and call it Hello4Shared.

In addition to that, for the right setup on the device of library ksoap2, you should create the 2nd project, where to place the library. You should define the type of the 2nd project Library and add the link to this project in the main application.

To work with the service, it’s necessary to add subclass ForSharedService.

The standard call of the function 4shared API will be the following:


protected static final String SERVICE_URL = "http://api.4shared.com/jax2/DesktopApp";        
    protected static final String SERVICE_NAMESPACE = "http://api.soap.shared.pmstation.com/";
 
/**
* Enter check of the already existing user 
* @param username – user name
* @param password - password
* @throws Exception
*/
 public void login(String username, String password) throws Exception
 {
 	String methodName = "login";
      SoapObject rpc = new SoapObject(SERVICE_NAMESPACE, methodName);
      rpc.addProperty("arg0", userName);
      rpc.addProperty("arg1", password);

SoapSerializationEnvelope envelope = new    SoapSerializationEnvelope(SoapEnvelope.VER11);

      envelope.bodyOut = rpc;        
      envelope.encodingStyle = SoapSerializationEnvelope.XSD;

      HttpTransport ht = new HttpTransport(SERVICE_URL);
	ht.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
	ht.debug = true;

        
      String result;

      ht.call(SERVICE_URL + "/" + methodName, envelope);
	result = (envelope.getResponse()).toString();         
        
      if (!isEmptyString(result))
      	throw new Exception(result);
}

The classes SoapObject, SoapSerializationEnvelope, HttpTransport – are included in the library ksoap2.

SoapObject, SoapSerializationEnvelope serve to parse soap-requests, whereas HttpTransport provides transport for the call of requests. The call of service functions itself is established by the method), of the class HttpTransport. The service answer can be received by means of calling the method getResponse() of the class SoapSerializationEnvelope. The parameters of functions, transferred to the service, are defined by calling up the method addProperty of the class SoapObject as a pair «parameter name - value». Now, let’s add the class of the main screen into the app, where we will place 2 text fields to enter the user’s name (login) and password, and the button to call up the method login of service, used to enter: public class MainAppScreen extends MainScreen implements FieldChangeListener

{
	/**
	 * Window Title
	 */
	private LabelField _title;
	
	/**
	 * Enter-Login Field
	 */
	private EmailAddressEditField _userNameField;
	
	/**
	 * Enter-Password Field
	 */
	private PasswordEditField _passwordField;
	
	/**
	 * Enter Button
	 */
	private ButtonField _loginButton;

	/**
	 * Constructor
	 */
	public MainAppScreen()
	{
		super();

		_title = new LabelField("Hello4Shared");
		setTitle(_title);
		
		_userNameField = new EmailAddressEditField("Login or email: ", "");
		add(_userNameField);
        _passwordField = new PasswordEditField("Password: ", "");
		add(_passwordField);

		_loginButton = new ButtonField("Login", Field.FOCUSABLE);
		_loginButton.setChangeListener(this);
		add(_loginButton);
	}
	
}

After that, let’s add the handler of the press-button in the following way:


/* 
 * The Handler of the Press-Button
*/
public void fieldChanged(Field field, int context)
{
	if (field == _loginButton)
	{
		login();
	}
}

And the exact request to 4shared service in the method login, by means of using the class ForSharedService, described above:


private void login(){
ForSharedService service = new ForSharedService(_userNameField.getText(), _passwordField.getText());
		
	// Logging into account
	try
	{
		service.login();
	}catch (Exception e)
	{
		Dialog.alert(e.getMessage());
	}
}

In case of invalid login or password, the user will receive the error report.

The full code of the demo-application is attached (http://dc315.4shared.com/download/bjixhTFj/blackberrysamples.zip).

Method Detail

Upload HOW TO

First of all you should check if you have enough free space in user’s account:

 function long getFreeSpace(String login, String password);

(returned value – free space in bytes)

And what is upload limit for user (per file):

 function long getMaxFileSize(String login, String password);

(returned value – maximum file size in bytes)

Please, check if target file corresponds the mentioned conditions, if it does, then:

Get session:

function String createUploadSessionKey(String login, String password, long dirID);

Set ‘-1’ as DirId parameter. In this case file will be uploaded to the root directory.

Or read full API description to learn how to browse user's directory for subdirectories' ids.

Return session key if everything is ok and empty or null string if you can't upload to the specified dir.

Get datacenter:

 function int getNewFileDataCenter(String login, String password);

If returned datacenter is less or equal then 0 - something goes wrong.

Then get URL for upload using session and datacenter:

 function String getUploadFormUrl(int dataCenterID, String sessionKey);

Returned string is only valid if it starts with http, otherwise, you can't upload file;

To reserve fileId for yor upload call function:

 function long uploadStartFile(String login, String password, long dirID, String name, long fullSize);

Again, fileId can be only positive.

Then use received URL and fileId to upload by executing POST query multipart/form-data with fields

1) resumableFileId (file ID received via previous method)

2) resumableFirstByte (index of the first byte of current part. If the file is uploaded as single unit – then pass 0. If the file is divided into parts and is uploaded by parts – then pass index of the byte every part starts from)

Attach the file to the query as a parameter FilePart.

where last parameter is file md5 digest. If the file is successfully uploaded – function returns null or empty line, if not – you will get an error message. If the file was uploaded by parts, this function unites them into one.

You are done!

Search files on 4shared

To search files on 4shared.com you should use the following url

http://search.4shared.com/network/searchXml.jsp

Parameters:

       q - keyword

Example: q=funny cats

       searchExtention - type of file (extension)
       
       searchCategory - category

If you need extension just use searchExtention=mid. Remember, if you are using parameter searchExtention you should also use searchmode=3

+Service 4shared is a usual web-service, '''WSDL description''' of which is here: https://api.4shared.com/jax2/DesktopApp?wsdl.
+You can '''read more about web-services and WSDL''' here: http://ru.wikipedia.org/wiki/%D0%92%D0%B5%D0%B1-%D1%81%D0%BB%D1%83%D0%B6%D0%B1%D0%B0, http://ru.wikipedia.org/wiki/WSDL.
+'''Short description of API functions''' can found here:  http://help.4shared.com/index.php/SOAP_API.
+To work with SOAP API, you can use direct SOAP-calling, but it’s more convenient to use another library for request parsing.
+For instance, you can use '''free library''': (http://code.google.com/p/ksoap2-android/), which uses Java Microedition, working on Blackberry OS).
+'''2. Demo Application'''
+In the beginning, it’s necessary to''' create the new project in Eclipse''' (menu File-New-Project, in the list of project types – select Blackberry Project) and call it Hello4Shared.
+In addition to that, for the right setup on the device of library ksoap2, you should create the 2nd project, where to place the library. You should define the type of the 2nd project Library and add the link to this project in the main application.
+To work with the service, it’s necessary to add ''' subclass ForSharedService'''.
+The s'''tandard call of the function 4shared API''' will be the following:
+<pre>
+protected static final String SERVICE_URL = "http://api.4shared.com/jax2/DesktopApp";
+    protected static final String SERVICE_NAMESPACE = "http://api.soap.shared.pmstation.com/";
+/**
+* Enter check of the already existing user
+* @param username – user name
+* @param password - password
+* @throws Exception
+*/
+ public void login(String username, String password) throws Exception
+ {
+ 	String methodName = "login";
+      SoapObject rpc = new SoapObject(SERVICE_NAMESPACE, methodName);
+      rpc.addProperty("arg0", userName);
+      rpc.addProperty("arg1", password);
+SoapSerializationEnvelope envelope = new    SoapSerializationEnvelope(SoapEnvelope.VER11);
+      envelope.bodyOut = rpc;
+      envelope.encodingStyle = SoapSerializationEnvelope.XSD;
+      HttpTransport ht = new HttpTransport(SERVICE_URL);
+	ht.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
+	ht.debug = true;
+      String result;
+      ht.call(SERVICE_URL + "/" + methodName, envelope);
+	result = (envelope.getResponse()).toString();
+      if (!isEmptyString(result))
+      	throw new Exception(result);
+}
+</pre>
+The classes '''SoapObject, SoapSerializationEnvelope, HttpTransport''' – are included in the library ksoap2.
+'''SoapObject, SoapSerializationEnvelope''' serve to parse soap-requests, whereas '''HttpTransport''' provides transport for the call of requests. The call of service functions itself is established by the method), of the class HttpTransport. The service answer can be received by means of calling the method getResponse() of the class SoapSerializationEnvelope. The parameters of functions, transferred to the service, are defined by calling up the method addProperty of the class SoapObject as a pair «parameter name - value».
+Now, let’s add the class of the main screen into the app, where we will place 2 text fields to enter the user’s name (login) and password, and the button to call up the method login of service, used to enter:
+public class MainAppScreen extends MainScreen implements FieldChangeListener
+<pre>
+{
+	/**
+	 * Window Title
+	 */
+	private LabelField _title;
+	/**
+	 * Enter-Login Field
+	 */
+	private EmailAddressEditField _userNameField;
+	/**
+	 * Enter-Password Field
+	 */
+	private PasswordEditField _passwordField;
+	/**
+	 * Enter Button
+	 */
+	private ButtonField _loginButton;
+	/**
+	 * Constructor
+	 */
+	public MainAppScreen()
+	{
+		super();
+		_title = new LabelField("Hello4Shared");
+		setTitle(_title);
+		_userNameField = new EmailAddressEditField("Login or email: ", "");
+		add(_userNameField);
+        _passwordField = new PasswordEditField("Password: ", "");
+		add(_passwordField);
+		_loginButton = new ButtonField("Login", Field.FOCUSABLE);
+		_loginButton.setChangeListener(this);
+		add(_loginButton);
+	}
+}
+</pre>
+After that, let’s '''add the handler''' of the press-button in the following way:
+<pre>
+/*
+ * The Handler of the Press-Button
+*/
+public void fieldChanged(Field field, int context)
+{
+	if (field == _loginButton)
+	{
+		login();
+	}
+}
+</pre>
+And the '''exact request to 4shared service''' in the method login, by means of using the class ForSharedService, described above:
+<pre>
+private void login(){
+ForSharedService service = new ForSharedService(_userNameField.getText(), _passwordField.getText());
+	// Logging into account
+	try
+	{
+		service.login();
+	}catch (Exception e)
+	{
+		Dialog.alert(e.getMessage());
+	}
+}
+</pre>
+In case of invalid login or password, the user will receive the error report.
