那是在vue的种类中:在api中调用方法如下(react刚开首学,还在做轻巧demo)

import {fetch} from 'api/fetch'
export const callAuthCode = (userPhone) => {
 return fetch({
 url: '/api/auth/code',
 method: 'post',
 data: ({
  userPhone: userPhone,
 }),
 })
}

因为大家那边的后台须求严俊区分get/post请求,所以封装的方法调用中必须含有method,如后台已经管理好,全体可进行post请求,则足以参照axios官方网址里面将艺术漫天改为.post

至于fetch方法的验证:首要开始展览打包了请求拦截,响应拦截,暗中同意请求体由json格式转变form格式,当然,那么些都以在axios官方网站里可以找到的,但是是聚众下了而已

关于请求底部分请不要直接套用,这是我们那边后台须求特出安插的,后台接口3端共用,必须区分是何地在调用

如上那篇基于axios封装fetch方法及调用实例正是我分享给大家的全体内容了,希望能给我们1个参阅,也指望我们多多帮忙帮客之家。

因为大家那边的后台须求严俊区分get/post请求,所以封装的秘诀调用中务必包涵method,如后台已经管理好,全体可进展post请求,则足以参照axios官方网址里面将艺术漫天改为.post

有关fetch方法的表明:首要进行李包裹装了请求拦截,响应拦截,默许请求体由json格式调换form格式,当然,那几个都以在axios官方网站里能够找到的,不过是汇聚下了而已

至于请求尾部分请不要直接套用,那是大家那边后台须求特别布署的,后台接口三端共用,必须区分是哪个地方在调用
