java - Android socket io事件和 channel

Question

如何添加事件和 channel ？

private void initSocketConnection() {
    try {
        mSocket = IO.socket("URL");
        connectSocket();
    } catch (URISyntaxException e) {
        throw new RuntimeException(e);
    }
}

private void connectSocket() {
    try {
        mSocket.connect();
        mSocket.on(Socket.EVENT_CONNECT, onConnect);
        mSocket.on(Socket.EVENT_CONNECT_ERROR, onError);
        mSocket.on(Socket.EVENT_DISCONNECT, onDisconnect);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

private Emitter.Listener onDisconnect = new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        Log.e("SOCKET_TEST", "DISCONNECTION SUCCESSFULL");
    }
};


/**
 * Receiver class for socket connected event
 */
private Emitter.Listener onConnect = new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        Log.e("SOCKET_TEST", "CONNECTION SUCCESSFULL");
    }
};

/**
 * Receiver for socket failed events
 */
private Emitter.Listener onError = new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        Log.e("SOCKET_TEST", "CONNECTION FAIL " + args.toString());
    }
};

我发送请求，返回 32:44/socket.io,"Invalid namespace"需要发送事件和 channel

我使用 https://github.com/socketio/socket.io-client-java库，我根据文档进行了所有操作，但没有任何效果。

而不是只创建一个套接字:

val socket = IO.socket("https://something.com/socket.io")

尝试下一个代码:

val opts = IO.Options()
opts.path = "/socket.io"

val socket = IO.socket("https://something.com", opts)

我在尝试尝试将 4/socket.io, "Invalid namespace"连接到套接字时遇到了同样的问题，上面的代码修复了它。
