Question

我无法从本地主机连接到同一房间。这些消息显示在服务器的控制台中，但没有出现在其他选项卡中。这是我的代码。你能帮忙吗？

这是我的服务器“逻辑”：

    var nsp = io.of('/my-namespace');
nsp.on('connection', function(socket){
  socket.join('ID');
  //console.log("connected!" +socket.toString());
  socket.on('Newmessage', function(msg){
    console.log(socket.client + " said "+ msg);
    let time =  moment(new Date()).format("HH:mm:ss").toString();
//    socket.broadcast.emit('message', msg,time);
io.to('ID').emit('Newmessage', msg,time);
console.log(socket.client.id + " said "+ msg);

这是我的客户“逻辑”：

获取消息

   componentDidMount(){
 this.state.socket  = io('/my-namespace');
// this.state.io = io();
 this.state.socket.on("Newmessage",
 (msg,time)=>{
   alert("new message incoming!");
  this.AppendMessage(msg,time,false);
 });
}

发布消息：

PostMessage =  (chat) => {
  let dateRecived = -1;
  let message = this.state.inputValue;
  let x = true;
  fetch('/api/world', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ post: this.state.inputValue }),
  })    
  .then(res => res.text())//response type
  .then(time => this.AppendMessage(this.state.inputValue ,time,true))
  .then((res)=>{ this.state.socket.emit("Newmessage",message); console.log(message); return res;})

  .finally(res => res = 1); //log the data;
}

javascript-从套接字io获取来自房间的消息以做出反应
