我想运行一个非常简单的HTTP服务器。对example.com的每个GET请求都应该得到index.html，但作为一个常规的HTML页面(即，与阅读普通网页时的体验相同)。
使用下面的代码，我可以读取index.html的内容。我如何服务index.html作为一个普通的网页?
var http = require('http');
var fs = require('fs');
var index = fs.readFileSync('index.html');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end(index);
}).listen(9615);
下面的一个建议很复杂，需要我为我想使用的每个资源(CSS、JavaScript、图像)文件写一个get行。
我如何能提供一个单一的HTML页面与一些图像，CSS和JavaScript?

当然，首先要安装node.js。后:
> # module with zero dependencies
> npm install -g @kawix/core@latest
> # change /path/to/static with your folder or empty for current
> kwcore "https://raw.githubusercontent.com/voxsoftware/kawix-core/master/example/npmrequire/express-static.js" /path/to/static
这里是“https://raw.githubusercontent.com/voxsoftware/kawix-core/master/example/npmrequire/express-static.js”的内容(你不需要下载，我贴出来是为了了解后面的工作原理)
// you can use like this:
// kwcore "https://raw.githubusercontent.com/voxsoftware/kawix-core/master/example/npmrequire/express.js" /path/to/static
// kwcore "https://raw.githubusercontent.com/voxsoftware/kawix-core/master/example/npmrequire/express.js"
// this will download the npm module and make a local cache
import express from 'npm://express@^4.16.4'
import Path from 'path'
var folder= process.argv[2] || "."
folder= Path.resolve(process.cwd(), folder)
console.log("Using folder as public: " + folder)
var app = express()
app.use(express.static(folder))
app.listen(8181)
console.log("Listening on 8181")
其他回答
与其处理switch语句，我认为从字典中查找内容类型更简洁:
var contentTypesByExtension = {
'html': "text/html",
'js': "text/javascript"
};
...
var contentType = contentTypesByExtension[fileExtension] || 'text/plain';
编辑:
Node.js示例应用Node Chat拥有你想要的功能。 在它的readme。textfile中 3.步伐就是你要找的。
step1 创建一个在端口8002上响应hello world的服务器 步骤2 创建一个index.html并服务它 步骤3 介绍util.js 更改逻辑，以便为任何静态文件提供服务 如果找不到文件，显示404 第四 添加jquery-1.4.2.js 添加client.js 将index.html更改为提示用户昵称
这是server.js
这是util.js
上面的大多数答案都很好地描述了内容是如何被提供的。我正在寻找作为额外的目录列表，以便该目录的其他内容可以被浏览。以下是我给更多读者的解决方案:
'use strict';
var finalhandler = require('finalhandler');
var http = require('http');
var serveIndex = require('serve-index');
var serveStatic = require('serve-static');
var appRootDir = require('app-root-dir').get();
var log = require(appRootDir + '/log/bunyan.js');
var PORT = process.env.port || 8097;
// Serve directory indexes for reports folder (with icons)
var index = serveIndex('reports/', {'icons': true});
// Serve up files under the folder
var serve = serveStatic('reports/');
// Create server
var server = http.createServer(function onRequest(req, res){
var done = finalhandler(req, res);
serve(req, res, function onNext(err) {
if (err)
return done(err);
index(req, res, done);
})
});
server.listen(PORT, log.info('Server listening on: ', PORT));
最快捷的方法:
var express = require('express');
var app = express();
app.use('/', express.static(__dirname + '/../public')); // ← adjust
app.listen(3000, function() { console.log('listening'); });
你的方法:
var http = require('http');
var fs = require('fs');
http.createServer(function (req, res) {
console.dir(req.url);
// will get you '/' or 'index.html' or 'css/styles.css' ...
// • you need to isolate extension
// • have a small mimetype lookup array/object
// • only there and then reading the file
// • delivering it after setting the right content type
res.writeHead(200, {'Content-Type': 'text/html'});
res.end('ok');
}).listen(3001);
