As the title, I encapsulated an own ajax request function.

Instructions for use

pass parameters

1. URL address
2. Request method (GET, POST)
3. request parameter
4. request header
5. Whether to request asynchronously (true, false), asynchronous request is enabled by default

GET

GET takes no parameters and no request headers:

 <script src="https://cdn.xxhzm.cn/request/request.min.js"></script> request('user/info', 'GET').then(val => { console.log(val) }).catch(val => { console.error(val) })

GET with parameters, without request headers:

 const data = { username: 'xxhzm', sex: '男', age: '16' } request('user/info', 'GET', data).then(val => { console.log(val) }).catch(val => { console.error(val) })

GET without parameters, with request headers

 const header = { 'Content-Type': 'text/html; charset=utf-8' } request('user/info', 'GET', null, header).then(val => { console.log(val) }).catch(val => { console.error(val) })

POST

post without parameters, without request headers

 request('user/info', 'POST').then(val => { console.log(val) }).catch(val => { console.log(val) })

post with parameters, without request headers

 const data = new URLSearchParams() data.append('name', 'xxhzm') data.append('sex', '男') data.append('age', '16') request('user/info', 'POST', data).then(val => { console.log(val) }).catch(val => { console.log(val) })

post without parameters, with request headers

 const header = { 'Content-Type': 'text/html; charset=utf-8' } request('user/info', 'POST', null, header).then(val => { console.log(val) }).catch(val => { console.log(val) })

extended spelling

 const userGet = async () => { const res = await request('user/info', 'GET') console.log(res) }
