Package com.opentok

Class OpenTok

java.lang.Object

com.opentok.OpenTok

public class OpenTok
extends java.lang.Object

Contains methods for creating OpenTok sessions, generating tokens, and working with archives.

To create a new OpenTok object, call the OpenTok constructor with your OpenTok API key and the API secret for your Vonage Video API account. Do not publicly share your API secret. You will use it with the OpenTok constructor (only on your web server) to create OpenTok sessions.

Be sure to include the entire OpenTok server SDK on your web server.

Constructor Detail

OpenTok

public OpenTok(int apiKey,
               java.lang.String apiSecret)

Creates an OpenTok object.

Parameters:

apiKey - Your OpenTok API key. (See your Vonage Video API account page.)

apiSecret - Your OpenTok API secret. (See your Vonage Video API account page.)

Method Detail

generateToken

public java.lang.String generateToken(java.lang.String sessionId,
                                      TokenOptions tokenOptions)
                               throws OpenTokException

Creates a token for connecting to an OpenTok session. In order to authenticate a user connecting to an OpenTok session, the client passes a token when connecting to the session.

The following example shows how to obtain a token that has a role of "subscriber" and that has a connection metadata string:

 import com.opentok.Role;
 import com.opentok.TokenOptions;

 class Test {
     public static void main(String argv[]) throws OpenTokException {
         int API_KEY = 0; // Replace with your OpenTok API key (see https://tokbox.com/account).
         String API_SECRET = ""; // Replace with your OpenTok API secret.
         OpenTok sdk = new OpenTok(API_KEY, API_SECRET);

         //Generate a basic session. Or you could use an existing session ID.
         String sessionId = System.out.println(sdk.createSession());

         // Replace with meaningful metadata for the connection.
         String connectionMetadata = "username=Bob,userLevel=4";

         // Use the Role value appropriate for the user.
         String role = Role.SUBSCRIBER;

         // Generate a token:
         TokenOptions options = new TokenOptions.Buider().role(role).data(connectionMetadata).build();
         String token = sdk.generateToken(sessionId, options);
         System.out.println(token);
     }
 }
 

For testing, you can also generate tokens by logging in to your Vonage Video API account.

Parameters:

sessionId - The session ID corresponding to the session to which the user will connect.

tokenOptions - This TokenOptions object defines options for the token. These include the following:

• The role of the token (subscriber, publisher, or moderator)
• The expiration time of the token
• Connection data describing the end-user

Returns:

The token string.

Throws:

OpenTokException

generateToken

public java.lang.String generateToken(java.lang.String sessionId)
                               throws OpenTokException

Creates a token for connecting to an OpenTok session, using the default settings. The default settings are the following:

• The token is assigned the role of publisher.
• The token expires 24 hours after it is created.
• The token includes no connection data.

The following example shows how to generate a token that has the default settings:

 import com.opentok.OpenTok;

 class Test {
     public static void main(String argv[]) throws OpenTokException {
         int API_KEY = 0; // Replace with your OpenTok API key (see https://tokbox.com/account).
         String API_SECRET = ""; // Replace with your OpenTok API secret.
         OpenTok sdk = new OpenTok(API_KEY, API_SECRET);

         //Generate a basic session. Or you could use an existing session ID.
         String sessionId = System.out.println(sdk.createSession().getSessionId());

         String token = sdk.generateToken(sessionId);
         System.out.println(token);
     }
 }
 

Parameters:

sessionId - The session ID corresponding to the session to which the user will connect.

Returns:

The token string.

Throws:

OpenTokException

See Also:

generateToken(String, TokenOptions)

createSession

public Session createSession(SessionProperties properties)
                      throws OpenTokException

Creates a new OpenTok session.

For example, when using the OpenTok.js library, use the session ID when calling the OT.initSession() method (to initialize an OpenTok session).

OpenTok sessions do not expire. However, authentication tokens do expire (see the generateToken(String, TokenOptions) method). Also note that sessions cannot explicitly be destroyed.

A session ID string can be up to 255 characters long.

Calling this method results in an OpenTokException in the event of an error. Check the error message for details.

The following code creates a session that attempts to send streams directly between clients (falling back to use the OpenTok TURN server to relay streams if the clients cannot connect):

 import com.opentok.MediaMode;
 import com.opentok.OpenTok;
 import com.opentok.Session;
 import com.opentok.SessionProperties;

 class Test {
     public static void main(String argv[]) throws OpenTokException {
         int API_KEY = 0; // Replace with your OpenTok API key.
         String API_SECRET = ""; // Replace with your OpenTok API secret.
         OpenTok sdk = new OpenTok(API_KEY, API_SECRET);

         SessionProperties sp = new SessionProperties().Builder()
           .mediaMode(MediaMode.RELAYED).build();

         Session session = sdk.createSession(sp);
         System.out.println(session.getSessionId());
     }
 }
 

You can also create a session using the OpenTok REST API or or by logging in to your Vonage Video API account.

Parameters:

properties - This SessionProperties object defines options for the session. These include the following:

• Whether the session's streams will be transmitted directly between peers or using the OpenTok Media Router.
• A location hint for the location of the OpenTok server to use for the session.

Returns:

A Session object representing the new session. Call the getSessionId() method of the Session object to get the session ID, which uniquely identifies the session. You will use this session ID in the client SDKs to identify the session.

Throws:

OpenTokException

createSession

public Session createSession()
                      throws OpenTokException

Creates an OpenTok session with the default settings:

• The media mode is "relayed". The session will attempt to transmit streams directly between clients. If two clients cannot send and receive each others' streams, due to firewalls on the clients' networks, their streams will be relayed using the OpenTok TURN Server.
• The session uses the first client connecting to determine the location of the OpenTok server to use.

The following example creates a session that uses the default settings:

 import com.opentok.OpenTok;
 import com.opentok.SessionProperties;

 class Test {
     public static void main(String argv[]) throws OpenTokException {
         int API_KEY = 0; // Replace with your OpenTok API key.
         String API_SECRET = ""; // Replace with your OpenTok API secret.
         OpenTok sdk = new OpenTok(API_KEY, API_SECRET);

         String sessionId = sdk.createSession();
         System.out.println(sessionId);
     }
 }
 

Returns:

A Session object representing the new session. Call the getSessionId() method of the Session object to get the session ID, which uniquely identifies the session. You will use this session ID in the client SDKs to identify the session.

Throws:

OpenTokException

Parameters:

archiveId - The archive ID of the archive you want to delete.

Throws:

To successfully start broadcasting a session, at least one client must be connected to the session.

You can only have one active live streaming broadcast at a time for a session (however, having more than one would not be useful). The live streaming broadcast can target one HLS endpoint and up to five RTMP servers simulteneously for a session. You can only start live streaming for sessions that use the OpenTok Media Router (with the media mode set to routed); you cannot use live streaming with sessions that have the media mode set to relayed OpenTok Media Router.
