我在npm上发现了一个有趣的库，可能对你有用。它叫做mime(npm install mime或https://github.com/broofa/node-mime)，它可以确定文件的mime类型。下面是我用它写的一个web服务器的例子:

var mime = require("mime"),http = require("http"),fs = require("fs");
http.createServer(function (req, resp) {
path  = unescape(__dirname + req.url)
var code = 200
 if(fs.existsSync(path)) {
    if(fs.lstatSync(path).isDirectory()) {
        if(fs.existsSync(path+"index.html")) {
        path += "index.html"
        } else {
            code = 403
            resp.writeHead(code, {"Content-Type": "text/plain"});
            resp.end(code+" "+http.STATUS_CODES[code]+" "+req.url);
        }
    }
    resp.writeHead(code, {"Content-Type": mime.lookup(path)})
    fs.readFile(path, function (e, r) {
    resp.end(r);

})
} else {
    code = 404
    resp.writeHead(code, {"Content-Type":"text/plain"});
    resp.end(code+" "+http.STATUS_CODES[code]+" "+req.url);
}
console.log("GET "+code+" "+http.STATUS_CODES[code]+" "+req.url)
}).listen(9000,"localhost");
console.log("Listening at http://localhost:9000")

这将服务于任何常规的文本或图像文件(.html， .css， .js， .pdf， .jpg， .png， .m4a和.mp3是我测试过的扩展名，但理论上它应该适用于所有文件)

开发人员指出

下面是我用它得到的输出示例:

Listening at http://localhost:9000
GET 200 OK /cloud
GET 404 Not Found /cloud/favicon.ico
GET 200 OK /cloud/icon.png
GET 200 OK /
GET 200 OK /501.png
GET 200 OK /cloud/manifest.json
GET 200 OK /config.log
GET 200 OK /export1.png
GET 200 OK /Chrome3DGlasses.pdf
GET 200 OK /cloud
GET 200 OK /-1
GET 200 OK /Delta-Vs_for_inner_Solar_System.svg

注意路径构造中的unescape函数。这是为了允许包含空格和编码字符的文件名。

var http = require('http');
var fs = require('fs');
var index = fs.readFileSync('index.html');

http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'html'});
res.end(index);
}).listen(9615);

//Just Change The CONTENT TYPE to 'html'

如果你的电脑上安装了节点，你可能有NPM，如果你不需要NodeJS的东西，你可以使用服务包来实现这个:

1 -在您的PC上安装软件包:

npm install -g serve

2 -提供静态文件夹:

serve <path> 
d:> serve d:\StaticSite

它会告诉你你的静态文件夹正在被服务的端口，只需像这样导航到主机:

http://localhost:3000

我使用下面的代码来启动一个简单的web服务器，如果Url中没有提到文件，它会渲染默认的html文件。

var http = require('http'),
fs = require('fs'),
url = require('url'),
rootFolder = '/views/',
defaultFileName = '/views/5 Tips on improving Programming Logic   Geek Files.htm';


http.createServer(function(req, res){

    var fileName = url.parse(req.url).pathname;
    // If no file name in Url, use default file name
    fileName = (fileName == "/") ? defaultFileName : rootFolder + fileName;

    fs.readFile(__dirname + decodeURIComponent(fileName), 'binary',function(err, content){
        if (content != null && content != '' ){
            res.writeHead(200,{'Content-Length':content.length});
            res.write(content);
        }
        res.end();
    });

}).listen(8800);

它将呈现所有的js, css和图像文件，以及所有的html内容。

同意“没有内容类型比错误的内容类型更好”的说法

你不需要快递。你不需要联系。Node.js执行http native。你所需要做的就是根据请求返回一个文件:

var http = require('http')
var url = require('url')
var fs = require('fs')

http.createServer(function (request, response) {
    var requestUrl = url.parse(request.url)    
    response.writeHead(200)
    fs.createReadStream(requestUrl.pathname).pipe(response)  // do NOT use fs's sync methods ANYWHERE on production (e.g readFileSync) 
}).listen(9615)    

一个更完整的例子，确保请求不能访问基目录下的文件，并进行适当的错误处理:

var http = require('http')
var url = require('url')
var fs = require('fs')
var path = require('path')
var baseDirectory = __dirname   // or whatever base directory you want

var port = 9615

http.createServer(function (request, response) {
    try {
        var requestUrl = url.parse(request.url)

        // need to use path.normalize so people can't access directories underneath baseDirectory
        var fsPath = baseDirectory+path.normalize(requestUrl.pathname)

        var fileStream = fs.createReadStream(fsPath)
        fileStream.pipe(response)
        fileStream.on('open', function() {
             response.writeHead(200)
        })
        fileStream.on('error',function(e) {
             response.writeHead(404)     // assume the file doesn't exist
             response.end()
        })
   } catch(e) {
        response.writeHead(500)
        response.end()     // end the response so browsers don't hang
        console.log(e.stack)
   }
}).listen(port)

console.log("listening on port "+port)

这基本上是连接版本3的公认答案的更新版本:

var connect = require('connect');
var serveStatic = require('serve-static');

var app = connect();

app.use(serveStatic(__dirname, {'index': ['index.html']}));
app.listen(3000);

我还添加了一个默认选项，以便index.html作为默认选项。
