1.创建服务器

let http = require("http");

//创建服务器
let server=http.createServer((req,res)=>{
    console.log(req.url);
    res.writeHead(200,{"Content-Type":"text/html;charset=UTF-8"})
    res.write("<h1>你好</h1>")
    res.end("hello xiaozhang")
}).listen(8080)

  

let http = require("http");
let fs=require('fs')

//创建服务器
let server=http.createServer((req,res)=>{
    if(req.url==='/page1'){
        fs.readFile('./text1.html',(err,data)=>{
            if(!err){
                res.writeHead(200,{"Content-Type":"text/html;charset=UTF-8"})
                res.end(data)
            }
        })
    }else if(req.url==='/page2'){
        fs.readFile('./text2.html',(err,data)=>{
            if(!err){
                res.writeHead(200,{"Content-Type":"text/html;charset=UTF-8"})
                res.end(data)
            }
        })
    }else if(req.url==='/'){//根目录
        res.writeHead(200,{"Content-Type":"text/html;charset=UTF-8"})
        res.end("<h1>hello xiaojin</h1>")
    }else if(req.url==='/css/index.css'){
        fs.readFile("./css/index.css",(err,data)=>{
            if(!err){
                res.writeHead(200,{"Content-Type":'text/css'})
                res.end(data)
            }
        })
    }else if(req.url==='/img/1.jpg'){
        fs.readFile("./img/1.jpg",(err,data)=>{
            if(!err){
                res.writeHead(200,{"Content-Type":'image/jpg'})
                res.end(data)
            }
        })
    }
    else{
        // console.log(req.url);
        res.writeHead(404,{"Content-Type":"text/html;charset=UTF-8"})
        res.end("<h1>访问的页面不存在</h1>")
    }
})

//监听
server.listen(80,"127.0.0.1")
