我似乎在browser-sync中使用的插座和我想用于socket.io的插座有冲突。我通过gulp任务（使用Aurelia CLI默认项目）使用browser-sync。会发生什么是只有browser-sync套接字似乎工作，并且主要用于服务器端的socket.io完全未读。我确实找到了解决该问题的GitHub issue #71，以及这两个都提到使用名称空间的其他Github issue #241。然而，我尝试了一些差异，即使它们运行有错误，但它不能解决我的任何问题。如何解决浏览器同步和socket.io冲突？
我主要使用Gulp与browser-sync的Aurelia CLI项目中，而后端是NodeJS与Koa。的[email protected]而[email protected]使用的端口的版本是前端：4000，后端：5000

使用具有Aurelia的Socket.io客户端（前端）
import io from 'socket.io-client';
var socket = io('http://localhost:5000');
// also tried with a namespace instead
//var socket = io('/todo-socket');
// ...
socket.on("todo_update", data => {
let pos = arrayFindObjectIndex(this.items, 'id', data.id);
if(pos >= 0) {
this.items.splice(pos, 1, data);
this.itemDoneCount = this.items.filter(x => x.completed).length;
}
});
周用的NodeJS兴亚（后端）
// Middlewares
const app = require('koa')();
const serve = require('koa-static');
const api = require('koa-router')();
const assertTimeout = require('co-assert-timeout');
const http = require('http');
const server = require('http').createServer(app.callback());
const io = require('socket.io')(server);
// or without namespace: io.sockets.on("connection", function(socket) {
var tsp = io.of('/todo-socket');
tsp.on("connection", function(socket) {
console.log('A new WebSocket client connected with ID: ' + socket.client.id);
})
.error(function(err){
console.log("Changefeeds Failure: ", err);
return null;
});
socket.on('disconnect', function(data) {
console.log('A WebSocket client disconnnected with ID: ' + socket.client.id);
return null;
});
我想有和没有命名空间，这似乎并没有改变任何东西。我提到browser-sync - socket option
编辑
从测试这个多，它实际上好像在服务器端socket.io是不工作的。它不会从服务器输出console.log('connected with ID: ' + socket.client.id)，但它不会显示或抛出任何错误。服务器端的代码与WebPack一起使用，所以我认为它与browserSync冲突有关。
