用Node创建一个静态web服务器(读取文件)

创建服务器
- 创建服务器的方法
http.cresteServer()//引入http模块 const http = require('http'); const { ESRCH } = require('constants'); //创建web服务方法是http.creatServer(()=>()).listen(3000) http.createServer((req,res)=>{ res.writeHead(200,{"Content-type":"text/html;charset='utf-8'"}); res.write('<head><meta charset="UTF-8"></head>') res.write('内容') res.end() }).listen(3000) console.log('http://127.0.0.1:3000')- 以上这个只能给客户端响应简单的数据
NodeJs创建一个web服务器(可以放置静态网站、下载web服务器上的文件)
- 代码(文件类型手动写死)
//NodeJs创建一个web服务器(可以放置静态网站、下载web服务器上的文件) //http://127.0.0.1:3000/index.html // 1.获取网站地址 const http = require('http') const fs = require('fs') const path = require('path') const url = require('url') const common = require('./module/name.js') http.createServer((req, res) => { // res.writeHead(200,{"Content-type":"text/html;charset='utf-8'"}) //http://127.0.0.1:3000/index.html // 1.获取网站地址 // let pathanme = req.url let pathanme = url.parse(req.url).pathname pathanme = pathanme == '/' ? '/index.html' : pathanme //path内置模块中有一个path.extname()方法获取后缀名 let extanme = path.extname(pathanme) // console.log(extanme) //2. 通过fs模块读取文件 if (pathanme != '/favicon.ico') { fs.readFile('./pack' + pathanme, (err, data) => { if (err) { res.writeHead(404, { "Conten-type": 'text/html;charset="utf-8"' }) res.write('<head><meta charset="UTF-8"></head>') res.end('页面不存在') } else { let mime = common.getMime(extanme) // res.writeHead(200,{"Conten-type":"text/html;charset='utf-8'"}) res.writeHead(200, { "Conten-type": '' + mime + ";charset='utf-8'" }) // res.write('<head><meta charset="UTF-8"></head>') res.end(data) } }) } }).listen(3000) console.log('http://127.0.0.1:3000') - 自己定义的模块
- module/name.js
exports.getMime=function(e){ //e外部使用是传入的后缀名 switch(e){ case '.html': return 'text/html'; case '.css': return 'text/css' case '.js': return 'text/javascript' default: return 'text/html'; } }

外部自定义模块/module/name.js
//异步的 const fs = require('fs') exports.getMimes = function (a) { return new Promise((resolve,reject)=>{ fs.readFile('data/Mime.json',(err,data)=>{ if(err){ console.log(err) reject(err) }else{ let site = JSON.parse(data.toString()) // return site[a] 这是异步的，如果直接返回会有问题的(需要做异步处理) // console.log(site[a]) resolve(site[a]) } }) }) } // console.log(this.getMimes('.js')) // this.getMimes('.js') -

和上面的唯一的区别是一个是上面是异步的(需要用到async await)，这里是同步的
