您可以使用Express使用Node加载和呈现基本的HTML文件。这大约需要10分钟才能开始。它被绑定到http.createServer()，所以你仍然在Node的土地上，可以轻松地删除它。

// app.js
const path = require('path');
const express = require('express');

const app = express();
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', express.static('index.html'));
app.use('/test', express.static('test.html'));

module.exports = app;

// server.js
const http = require('http');
const PORT = process.env.PORT || 3000;

const appServer = require('./app');
const httpServer = http.createServer(appServer);

httpServer.listen(PORT);
console.log(`Listening on port ${PORT}...`);

我只是发现了一种使用fs库的方法。但我不确定它是不是最干净的。

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


fs.readFile('./index.html', function (err, html) {
    if (err) {
        throw err; 
    }       
    http.createServer(function(request, response) {  
        response.writeHeader(200, {"Content-Type": "text/html"});  
        response.write(html);  
        response.end();  
    }).listen(8000);
});

基本概念就是读取原始文件并转储内容。不过，仍然有更清洁的选择!

您可以使用fs对象手动回显文件，但我建议使用ExpressJS框架使您的工作更容易。

.．.但如果你坚持用艰难的方式来做:

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

http.createServer(function(req, res){
    fs.readFile('test.html',function (err, data){
        res.writeHead(200, {'Content-Type': 'text/html','Content-Length':data.length});
        res.write(data);
        res.end();
    });
}).listen(8000);

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

  http.createServer(function(request, response) {  
    response.writeHeader(200, {"Content-Type": "text/html"});  
    var readSream = fs.createReadStream('index.html','utf8')
    readSream.pipe(response);
  }).listen(3000);

 console.log("server is running on port number ");

我知道这是一个老问题——如果你不喜欢使用connect或express，这里有一个简单的文件服务器实用工具;而是HTTP模块。

var fileServer = require('./fileServer');
var http = require('http');
http.createServer(function(req, res) {
   var file = __dirname + req.url;
   if(req.url === '/') {
       // serve index.html on root 
       file = __dirname + 'index.html'
   }
   // serve all other files echoed by index.html e.g. style.css
   // callback is optional
   fileServer(file, req, res, callback);

})
module.exports = function(file, req, res, callback) {
    var fs = require('fs')
        , ext = require('path').extname(file)
        , type = ''
        , fileExtensions = {
            'html':'text/html',
            'css':'text/css',
            'js':'text/javascript',
            'json':'application/json',
            'png':'image/png',
            'jpg':'image/jpg',
            'wav':'audio/wav'
        }
    console.log('req    '+req.url)
    for(var i in fileExtensions) {
       if(ext === i) {    
          type = fileExtensions[i]
          break
       }
    }
    fs.exists(file, function(exists) {
       if(exists) {
          res.writeHead(200, { 'Content-Type': type })
          fs.createReadStream(file).pipe(res)
          console.log('served  '+req.url)
          if(callback !== undefined) callback()
       } else {
          console.log(file,'file dne')
         }  
    })
}

增加另一个选项-基于例外的答案。

打字稿:

import { Injectable } from '@nestjs/common';
import { parse } from 'node-html-parser';
import * as fs from 'fs';
import * as path from 'path'


@Injectable()
export class HtmlParserService {


  getDocument(id: string): string {

      const htmlRAW = fs.readFileSync(
          path.join(__dirname, "../assets/files/some_file.html"),
          "utf8"
      );


      const parsedHtml = parse(htmlRAW);
      const className  = '.'+id;
      
      //Debug
      //console.log(parsedHtml.querySelectorAll(className));

      return parsedHtml.querySelectorAll(className).toString();
  }
}

(*)上面的例子是使用nestjs和node-html-parser。
