【问题描述】：

我正在构建一个使用 socket.io 和 web worker api 每秒从服务器获取更新的 web 应用程序。其中一个按钮正在打开一个新窗口，当打开新窗口时，socket.io 停止工作并获得错误的请求响应

//part of the code

var socket = io(transports: ['polling']);

worker = new Worker("web_worker.js");

worker.onmessage = function(event)
   socket.emit("check_for_updates");   
 

//this function is called when a button is pressed
function new_window(client)

    var uid = client.uid;
    var new_window = window.open("/new?uid="+uid);

控制台中显示的错误：

polling-xhr.js:270 GET http://localhost/socket.io/?EIO=3&transport=polling&t=Mv0tQCC&sid=LnzFU8ClZrY0NHK5AA-r 400（错误请求）

polling-xhr.js:270 POST http://localhost/socket.io/?EIO=3&transport=polling&t=Mv0tQC-&sid=LnzFU8ClZrY0NHK5AA-r 400（错误请求）

【参考方案1】：

所以我设法解决了问题-问题是在新窗口中我使用默认设置打开了一个新套接字，这导致第一个套接字崩溃。我的解决方案是使用 Sockt.io 码头的命名空间-

服务器端：

var main_socket = io(http);
socket = main_socket.of('/first');
socket.once("connection", (socket) =>
    console.log("user connected");

    socket.on("disconnect", function()
        console.log("user disconnected");
    );

var second_socket = main_socket.of('/second');
second_socket.once("connection", (second_socket) =>
    console.log("second connection");

客户端：

//part of the code

var socket = io(nsp="/first",Option=transports: ['polling']);

worker = new Worker("web_worker.js");

worker.onmessage = function(event)
   socket.emit("check_for_updates");   
 

//this function is called when a button is pressed
function new_window(client)

    var socket = io(nsp="/second",Option=transports: ['polling']);
    var uid = client.uid;
    var new_window = window.open("/new?uid="+uid);

希望以后能帮到别人
