如何添加事件和频道？

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());
    }
};

我发送一个请求，返回32:44/socket.io,"Invalid namespace" 需要发送事件和频道

我使用库 https://github.com/socketio/socket.io-client-java 我按照文档做所有事情，但没有任何效果。

标签： java android sockets socket.io

【解决方案1】：

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)

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