Please see the Socket.IO website for alternatives.
A Socket.IO client written in Java. See the offical Socket.IO website for more information.
This project has a dependency on TooTallNate/Java-WebSocket, a barebones WebSocket client and server implementation written in 100% Java.
Here is how you connect to a Socket.IO server at localhost:80:
IOSocket socket = new IOSocket("http://localhost:80", new MessageCallback() {
@Override
public void on(String event, JSONObject... data) {
// Handle events
}
@Override
public void onMessage(String message) {
// Handle simple messages
}
@Override
public void onMessage(JSONObject message) {
// Handle JSON messages
}
@Override
public void onConnect() {
// Socket connection opened
}
@Override
public void onDisconnect() {
// Socket connection closed
}
});
socket.connect();
If you're using the namespace feature of Socket.IO, you can also set that in the socket address:
IOSocket socket = new IOSocket("http://localhost:80/chat", ...)
Once the connection is opened, you can send messages to the server:
// simple message
socket.send("Hello world");
// event with a json message
socket.emit("see", new JSONObject().put("name", "Spot").put("action", "run"));
