前言

我是歌谣今天给大家带来的是关于node中新版url模块的一个讲解

案例1

const http = require("http")
const url=require("url")
//创建服务器
http.createServer((req, res) => {
    // console.log(url.parse(req.url).pathname)
    // var pathname=url.parse(req.url).pathname
    // var urlobj=url.parse(req.url,true)
    // console.log(urlobj.query.name,urlobj.query.age)
    // if (req.url === "/home") {
    // }
    var myurl=new URL(req.url,"http://127.0.0.1:3000")
    console.log(myurl,"myurl is")
    var pathname=""
    res.writeHead(renderStatus(pathname), { "Content-Type": "text/html;charset=utf-8" })
    res.write(renderHtml(pathname))
    res.end()


}).listen(3002, () => {
    console.log("geyao.....")
})
function renderHtml(url) {
    switch (url) {
        case "/home":
            return `<html>
            <p>hello home</p>
        </html>`;
        case "/list":
            return `<html>
            <p>hello list</p>
        </html>`;
        default:
            return `<html>
            <p>hello 404</p>
        </html>`;


    }
}
function renderStatus(url){
    var arr=["/home","/list"]
    return arr.includes(url)?200:404
}

运行结果

案例2

const http = require("http")
const url=require("url")
//创建服务器
http.createServer((req, res) => {
    // console.log(url.parse(req.url).pathname)
    // var pathname=url.parse(req.url).pathname
    // var urlobj=url.parse(req.url,true)
    // console.log(urlobj.query.name,urlobj.query.age)
    // if (req.url === "/home") {
    // }
    var myurl=new URL(req.url,"http://127.0.0.1:3000")
    console.log(myurl,"myurl is")
    for(var [key,value] of myurl.searchParams){
        console.log(key,value)
    }
    var pathname=myurl.pathname
    res.writeHead(renderStatus(pathname), { "Content-Type": "text/html;charset=utf-8" })
    res.write(renderHtml(pathname))
    res.end()


}).listen(3002, () => {
    console.log("geyao.....")
})
function renderHtml(url) {
    switch (url) {
        case "/home":
            return `<html>
            <p>hello home</p>
        </html>`;
        case "/list":
            return `<html>
            <p>hello list</p>
        </html>`;
        default:
            return `<html>
            <p>hello 404</p>
        </html>`;


    }
}
function renderStatus(url){
    var arr=["/home","/list"]
    return arr.includes(url)?200:404
}
