无法获取socket.io.js [英] Can't get socket.io.js

问题描述

我实际上是在一个小项目，我应该重新创建一个绘图多人游戏与node.js，mongoDB，socket.io和画布。

抽屉正在像一个魅力，服务器似乎也很好。我的注册/登录/会话和数据库正常工作，唯一的问题是socket.io。当用户加入游戏室时，他可以看到抽屉和工具，但没有连接。为什么浏览器找不到socket.io.js。

我做了什么：

我验证是否已安装，它是使用npm安装socket.io。
我检查服务器是否启动时，打开服务器：在我的控制台中有socket.io启动。
我检查了我的HTML代码，这里是：

 < script type =text / javascriptsrc = /socket.io/socket.io.js\"></script> 
  

根据数十亿个教程/ dev网站/帮助主题，这应该是有效的。但不是。当我打开浏览器的控制台时，我得到这个：

  X GET http：// localhost：1337 / socket.io / socket.io.js没有发现。 
  

我不知道问题在哪里，我无法想像出来，它给了我一个巨大的头痛..所以我在这里。

提前感谢帮助！ ：）

解决方案

鉴于您的评论中的代码，您没有使用正确的变量来初始化 socket.io 。

尝试这样：

  var express = require（'express'）; 
 var app = express（）; 
 var server = app.listen（1337）; 
 var io = require（'socket.io'）。listen（server）; 
 ... 
  

所以代替 socket.io '听'Express应用程序实例，它应该听什么 app.listen（...）返回（这恰好是一个 http.Server 实例）。

I'm actually working on a little project, where i'm supposed to recreate a drawing multiplayer game with node.js, mongoDB, socket.io and canvas.

The drawer is working like a charm, and the server seems to work well too. I got my register/login/sessions and database up and working, the only problem is socket.io. When an user is joining the game room, he can see the drawer and tools, but no connection. Why ? The browser can't find socket.io.js.

What I did :

I verified if it was installed, it is with npm install socket.io. I checked if the server was starting it when turning the server on : Got "socket.io started" in my console. I checked my HTML code, here it is :

<script type="text/javascript" src="/socket.io/socket.io.js"></script>

According to the billions of tutorials/dev sites/help subjects, this is supposed to work. But it's not. When opening the console of my browser, I got this :

X GET http://localhost:1337/socket.io/socket.io.js NOT FOUND.

I don't know where is the problem, I can't figure this out and it's giving me a huge headache.. So I'm here.

Thanks in advance for helping ! :)

解决方案

Given the code in your comment, you're not using the correct variable for initializing socket.io.

Try this:

var express = require('express');
var app     = express();
var server  = app.listen(1337);
var io      = require('socket.io').listen(server);
...

So instead of having socket.io 'listen' on the Express app instance, it should listen to what app.listen(...) returns (which happens to be an http.Server instance).
