服务端代码
const http = require('http')
const fs = require('fs')
const url = require('url')
const querystring = require('querystring')
const server = http.createServer((req, res) => {
let str = ''
console.log(req.url, req.method);
let { pathname, query } = url.parse(req.url, true)
switch (pathname) {
case '/login':
req.on('data', data => {
//不推荐 以后会有其他方式
str += data
})
req.on('end', () => {
console.log(str);
// console.log(querystring.parse(str));
let { name, password } = querystring.parse(str)
res.write(`name:${name} password:${password} success`)
res.end()
})
break
case '/sum':
console.log(query);
let { a, b } = query
res.write(`${a}+${b}=2333`)
res.end()
break
default:
fs.readFile('www/home.html', (err, data) => {
if (err) {
res.writeHead(404)
res.write('404 Not Found')
} else {
res.write(data)
}
res.end()
})
}
})
server.listen(8080, () => {
console.log('http://localhost:8080/');
})
