javascript - 如何使用 Socket.io 在一条消息中发送两个变量？

Question

我有一个客户端 ID 和用户名，我希望它们都通过套接字发送。

 client.userid = userid;
 client.username = username;
 client.emit('onconnected', { id: client.userid, name: client.username });

我试过这个，但它似乎不起作用

你可以试试这个

io.sockets.on('connection', function (socket) {
  socket.on('event_name', function(data) {
      // you can try one of these three options

      // this is used to send to all connecting sockets
      io.sockets.emit('eventToClient', { id: userid, name: username });
      // this is used to send to all connecting sockets except the sending one
      socket.broadcast.emit('eventToClient',{ id: userid, name: username });
      // this is used to the sending one
      socket.emit('eventToClient',{ id: userid, name: username });
  }
}

在客户端

 socket.on('eventToClient',function(data) {
    // do something with data
       var id = data.id
       var name = data.name // here, it should be data.name instead of data.username

 });
