Java Tambur.io REST API Client Build Status

Tambur.io provides a pain-free websocket experience.

Preliminary

Install this library preferably using maven:

git clone git://github.com/tamburio/java-tambur.git
cd java-tambur
mvn install

Please register on Tambur.io and create at least one app. This will give you the unique API_KEY, an APP_ID and a SECRET, which you need to initialize the client.

Example

import io.tambur.*;
/* ... */

Tambur tambur = new Tambur(API_KEY, APP_ID, SECRET);
tambur.publish("mystream", "some message");

The example above publishes the given message to all subscribed clients. Clients can set different modes for streams they have subscribed. Currently the Tambur.io supports a 'auth', 'presence', and 'direct' mode. But you must grant permission by issueing a specific mode token. For generating such tokens you typically need the StreamName, the SubscriberId, and for direct- and presence-modes the UserId. The SubscriberId is the only parameter your clients must send you e.g. through some AJAX request which you can answer with the generated mode token.

Auth Mode

If you issue an auth mode token, the client can authenticate himself for a particular stream. If you use the auth: stream prefix you can control how we deliver your message.

tambur.publish("auth:mystream", "some auth message");

The example above publishes the given message to all subscribed clients that have the auth mode enabled. Issuing an auth mode token is straight forward:

String authToken = tambur.generateAuthToken("mystream", subscriberId);

Presence Mode

If you issue a presence mode token, the client can switch on and off presence mode. If presence mode is switched on the client will receive join- and leave-events of all the other presence clients in that particular stream. Issuing a presence mode token needs an extra 'User-Id' parameter, which enables you to connect a tambur.io subscriber-id to a User-Id used in your application:

String presenceToken = tambur.generatePresenceToken("mystream", "Alice", subscriberId);

Direct Mode

If you issue a direct mode token, the client can switch on and off direct mode. If direct mode is switched on the client can send and receive messages from other clients in that particular stream. Issuing a direct mode token needs an extra 'User-Id' parameter, which enables you to connect a tambur.io subscriber-id to a User-Id used in your application:

String directToken = tambur.generateDirectToken("mystream", "Alice", subscriberId);

Private Messages

If you want to further limit your receivers to one specific subscriber you can do this using the 'private' stream.

tambur.publish("private:" + subscriberId, "some private message");
