前言

我是歌谣今天给大家带来的是关于node中url模块的一个讲解

安装nodemon

代码语言：javascript复制

npm i -g nodemon

案例1

代码语言：javascript复制

const http = require("http")
const url=require("url")
//创建服务器
http.createServer((req, res) => {
    console.log(url.parse(req.url).pathname)
    if (req.url === "/home") {


    }
    res.writeHead(renderStatus(req.url), { "Content-Type": "text/html;charset=utf-8" })
    res.write(renderHtml(req.url))
    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
}
