将Unity3d与Node.js连接

Question

我试图使用socket.io将我的unity3d程序与node.js服务器连接起来.

使用UnitySocketIO,我成功完成了客户端和服务器之间的连接.

但是,On或Emit方法不起作用.

有人可以帮我解决这个问题吗？

void Start () {

    string socketUrl = "http://127.0.0.1:50122";
    Debug.Log("socket url: " + socketUrl);

    this.socket = new Client(socketUrl);
    this.socket.Opened += this.SocketOpened;
    this.socket.Message += this.SocketMessage;
    this.socket.SocketConnectionClosed += this.SocketConnectionClosed;
    this.socket.Error += this.SocketError;

    this.socket.Connect();
}

private void SocketOpened (object sender, EventArgs e) {
    Debug.Log("socket opened");                  // i got this message
    this.socket.On ("message", (data) => {
        Debug.Log ("message : " + data);
    });
    this.socket.Emit("join", "abc"); 
    Debug.Log("Emit done");                  // i got this message
}

....

io.sockets.on('connection', function (socket) {

    console.log('connect');                  // i got this message

    socket.emit('message', 'Hello World!');

    socket.on('join', function (id) {
        console.log('client joined with id ' + id);
        socket.emit('message', 'Hello ' + id);
    });
});

您的活动可能以错误的顺序附加，请尝试如下：

void Start() {
    string socketUrl = "http://127.0.0.1:50122";
    Debug.Log("socket url: " + socketUrl);

    this.socket = new Client(socketUrl);
    this.socket.Opened += this.SocketOpened;
    this.socket.Message += this.SocketMessage;
    this.socket.SocketConnectionClosed += this.SocketConnectionClosed;
    this.socket.Error += this.SocketError;

    this.socket.On("message", (data) => {
        Debug.Log("message: " + data);
    });

    this.socket.Connect();
}

对于节点：

io.sockets.on('connection', function(socket) {
  console.log('client connected');
  socket.emit('message', 'Hello World!');
});

也不允许客户决定自己的 ID，因为在大多数情况下它是“可破解的”。只有服务器才应该做出重要的决定，而不是客户端。
