package.json file

npm install finalhandler --save

npm install serve-static --save

{ "dependencies": { "finalhandler": "^1.1.1", "serve-static": "^1.13.2" } }

The most important get.js

//这个案例展示get请求参数如何获得 var finalhandler = require('finalhandler') var serveStatic = require('serve-static')//之前安装的两个依赖 var http = require('http') var url = require('url') var fs = require('fs')//node内置模块 // Serve up public/ftp folder //配置静态资源服务器，将public文件夹静态化出来 var serve = serveStatic('public', {'index': ['index.html', 'index.htm']}) // Create server var server = http.createServer(function onRequest (req, res) { //路由 var pathname = url.parse(req.url).pathname; if(pathname == '/addStudent'){ //拿到GET请求参数，就是拿到地址栏中的东西。 var queryJSON = url.parse(req.url,true).query; var data = `姓名：${queryJSON.name}\r\n年龄：${queryJSON.age}\r\n性别：${queryJSON.sex}\r\n`; fs.writeFile(`./student_data/${queryJSON.name}.txt`,data,(err) => {//判断如果是addStudent这个接口，会获得数据后自动生成一个txt文件 //console.log(err); //返回状态码 if(err){ res.end('cuowu'); }else{ res.end('ok'); } }) return; } serve(req, res, finalhandler(req, res)) }) // Listen server.listen(3000)

The last step is to open your terminal, find the directory where get.js is located and then

node get.js

Copy after login
