【Node.js】路由之请求GET与POST参数

GET方法

1.原生node请求get参数

const express = require('express');
const url = require('url');
let app = express();
// 原生node写法
app.get("/index", (req, res) => {
    let { query } = url.parse(req.url, true);
    res.send(`GET I am ${query.name} and my age is ${query.age}`);
})
app.listen(3000, () => {
    console.log("Port 3000 is listening...");
})

2.express框架请求get参数

const express = require('express');
const url = require('url');
let app = express();

// express框架请求get参数
app.get("/index", (req, res) =>{
    let query = req.query;
    // console.log(query);
    res.send(`GET I am ${query.name} and my age is ${query.age}`);
})

app.listen(3000, () => {
    console.log("Port 3000 is listening...");
})
