Post acquisition parameters
Express post request parameters received packets need to use a third-party body-parser
//引入body-parser模块
const bodyParser = require('body-parser');
//配置body-parser模块
app.use(bodyParser.urlencoded({ extended:false}));
//接收请求
app.post('/add',(req,res)=>{
//接收请求参数
console.log(req.body)
})- extended: false: using a system module represents the querystring to deal with, but also the official recommendation
- extended: true: indicate the use of third-party modules to handle qs
- From functional terms, qs to be more powerful than querystring, so here can be considered based on the actual needs of the project
//10.js
//引入express框架
const express = require('express');
const bodyParser = require('body-parser');
//创建网站服务器
const app = express();
//拦截所有的请求
app.use(bodyParser.urlencoded({extended:false}));
app.post('/add',(req,res)=>{
//获取请求参数
res.send(req.body)
})
//监听端口
app.listen(3000);
console.log('网站服务器启动成功');
//post.html
