如何使websocket服务器在路由器上

Question

我正在写一个websocket服务器使用nodejs-ws模块，但服务器只能在服务器的根，所以我怎么能使它在子路由器像localhost:3000/聊天?

我需要你的帮助，非常感谢!

Answer 1

工作示例:

var ws = require('ws');
var http = require('http');
var httpServer = http.createServer();
httpServer.listen(3000, 'localhost');
var ws1 = new ws.Server({server:httpServer, path:"/chat"});
ws1.on('connection', function(){
  console.log("connection on /chat");
});
var ws2 = new ws.Server({server:httpServer, path:"/notifications"});
ws2.on('connection', function(){
  console.log("connection on /notifications");
});

你能告诉我在快递中怎么用吗?

要用Express路由websockets，我宁愿使用Express -ws-routes

var express = require('express');
var app = require('express-ws-routes')();
app.websocket('/myurl', function(info, cb, next) {
    console.log(
        'ws req from %s using origin %s',
        info.req.originalUrl || info.req.url,
        info.origin
    );
    cb(function(socket) {
        socket.send('connected!');
    });
});
