在Node.js上的相同地址处提供WebSocket和HTTP服务器 [英] Serve WebSocket and HTTP server at same address on Node.js

问题描述

我使用Node.js在端口8888上设置了 Websocket服务器 。我还有一个与Websocket后端（聊天服务器）交互的接口。

I have set up a Websocket server on port 8888, using Node.js. I also have an interface for that which interacts with the Websocket backend (chat server).

当使用浏览器访问服务器时，如何提供index.html（带有CSS / JS文件）？

How do I serve the index.html (with it's CSS/JS files) when the server is accessed using a browser?

推荐答案

如果您不想使用 socket.io ，但 websocket 包，您可以将它与快递，如下所示：

If you don't want to use socket.io, but the websocket package, you can use it in combination with Express like this:

// app.js
var WebSocketServer = require('websocket').server;
var express         = require('express');
var app             = express();
var server          = app.listen(8888);
var wsServer        = new WebSocketServer({ httpServer : server });

// this will make Express serve your static files
app.use(express.static(__dirname + '/public'));

// the rest of your code
wsServer.on('request', function(r) { ...

express.static 将负责提供您的HTML / CSS / JS文件。您传递的参数是目录这些文件所在的位置（在这种情况下，目录 public / 相对于 app.js 所在的位置）。

express.static will take care of serving your HTML/CSS/JS files. The argument you pass is the directory where those files are located (in this case, the directory public/ relative to where app.js is located).
