使用:
import myFetch from './fetch.js';
// 通用,传method,不传默认get
myFetch.fetchAll('http://xxxxxxxxxxxxx', {
xxxxx: xxxxx,
xxxxx: 'xxxxxxxxxxxxxx'
}).then(res => {
console.log(res);
}).catch(err => {
console.log(err);
})
// get
myFetch.fetchGet('http://xxxxxxxxxxxxx', {
xxxxx: xxxxx,
xxxxx: 'xxxxxxxxxxxxxx'
}).then(res => {
console.log(res);
}).catch(err => {
console.log(err);
})
// post
myFetch.fetchPost('http://xxxxxxxxxxxxx', {
xxxxx: xxxxx,
xxxxx: 'xxxxxxxxxxxxxx'
}).then(res => {
console.log(res);
}).catch(err => {
console.log(err);
})
