Question

我在向特定客户端发送私人消息时遇到问题。这个事件＆＃34;对话私人帖子＆＃34;没有工作，我的客户从未看到这些私人信息。

我不知道出了什么问题。

这是我的代码：

server.js

io.on('connection', function (socket, username) {
    console.log('New client connected (id=' + socket.id + ').');

    socket.on('subscribe', function(room) {
        console.log('joining room', room);
        socket.join(room);
    });

    socket.on('send message', function(data) {
        console.log('sending room post', data.room);
        socket.to(data.room).emit('conversation private post', {
            message: data.message
        });
    });
});

client.js

  <html>

    <head>
    <title>Getting started with Sockets</title>
    <script src="https://cdn.socket.io/socket.io-1.2.0.js"></script>

    <script>
       var conversation_id  = Math.floor(Math.random() * 1000 )
       var socket = io('http://localhost:3000');
       socket.emit('subscribe', conversation_id);

       socket.emit('send message', {
           room: conversation_id,
           message: "Some message"
       });

       socket.on('conversation private post', function(data) {
          console.log("Private conversation", data)
       });
     </script>

   </head>

   <body>
     <div id="serverMsg">Waiting for the message from server:</div>
  </body>

</html>

在客户端上，使用以下数据向服务器发出一个对象：

{
    to: [the other receiver's username as a string] ,
    from: [the person who sent the message as string] ,
    message: [the message to be sent as string]
}

在服务器上，侦听消息。收到消息后，将数据发送给接收方。

"the user you want to send"[data.to].emit('receivedMessage', data)

使用socket io向客户端发送私人消息
