node.js - 請問如何解決socket.io的跨域問題

Question

客戶端程式碼（client.html）：

var socket = io.connect('localhost:80');

服務端（server.js）：

io = require('socket.io').listen("80",{origins:'*'});

在本機可以正常運行，放到本機伺服器，提示

XMLHttpRequest cannot load http://localhost/socket.io/?E... No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://jess. dev' is therefore not allowed access. The response had HTTP status code 404.
