创建一个节点服务器来服务任何被请求的文件是很容易的，你不需要为它安装任何包

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

http.createServer(function (req, res) {
  var q = url.parse(req.url, true);
  var filename = "." + q.pathname;
  fs.readFile(filename, function(err, data) {
    if (err) {
      res.writeHead(404, {'Content-Type': 'text/html'});
      return res.end("404 Not Found");
    }  
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.write(data);
    return res.end();
  });
}).listen(8080);

http://localhost:8080/file.html

将从磁盘上提供file.html

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);

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)

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));

Node.js webserver

没有第三方框架;允许查询字符串;添加尾随斜杠;处理404

创建一个public_html子文件夹，并将所有内容放在其中。

要点:https://gist.github.com/veganaize/fc3b9aa393ca688a284c54caf43a3fc3

var fs = require('fs');

require('http').createServer(function(request, response) {
  var path = 'public_html'+ request.url.slice(0,
      (request.url.indexOf('?')+1 || request.url.length+1) - 1);
      
  fs.stat(path, function(bad_path, path_stat) {
    if (bad_path) respond(404);
    else if (path_stat.isDirectory() && path.slice(-1) !== '/') {
      response.setHeader('Location', path.slice(11)+'/');
      respond(301);
    } else fs.readFile(path.slice(-1)==='/' ? path+'index.html' : path,
          function(bad_file, file_content) {
      if (bad_file) respond(404);
      else respond(200, file_content);
    });
  });
 
  function respond(status, content) {
    response.statusCode = status;
    response.end(content);
  }
}).listen(80, function(){console.log('Server running on port 80...')});
