推荐答案

Copying socket.io.js 到公共文件夹(类似于 resources/js/socket.io.js) 不是正确的方法.

Copying socket.io.js to a public folder (something as resources/js/socket.io.js) is not the proper way to do it.

如果 Socket.io 服务器正确侦听您的 HTTP 服务器，它将自动通过 http://localhost:<port> 提供客户端文件;/socket.io/socket.io.js，您不需要在可公开访问的文件夹中找到它或将其复制为 resources/js/socket.io.js &手动提供.

If Socket.io server listens properly to your HTTP server, it will automatically serve the client file to via http://localhost:<port>/socket.io/socket.io.js, you don't need to find it or copy in a publicly accessible folder as resources/js/socket.io.js & serve it manually.

代码示例
Express 3.x -Express 3 要求您实例化一个 http.Server 以将 socket.io 附加到第一个

Code sample
Express 3.x - Express 3 requires that you instantiate a http.Server to attach socket.io to first

var express = require('express')
  , http = require('http');
//make sure you keep this order
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);

//... 

server.listen(8000);

快乐编码:)
