问题描述

我继续收到错误
/socket.io/socket.io.js 404（未找到）
未捕获的ReferenceError：io未定义

i keep on getting the error /socket.io/socket.io.js 404 (Not Found) Uncaught ReferenceError: io is not defined

我的代码是

var express = require('express'), http = require('http');
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);

server.listen(3000);

和

<script src="/socket.io/socket.io.js"></script>

有什么问题???

推荐答案

复制 socket.io.js 到公共文件夹（ resources / js / socket.io.js 这样的东西）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 服务器正确监听 HTTP 服务器，它将自动将客户端文件提供给通过 http：// localhost：< port> /socket.io/socket.io.js ，您无需在可公开访问的文件夹中找到它或复制as 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http.Server以附加 socket.io 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);
