关于javascript:Fetch在项目中灵活使用

fetch的兼容

import 'fetch-detector' //fetch的兼容包import 'fetch-ie8'

Fetch的post申请

const fetchPost = (url,params)=>{ return fetch(url,{ method:"POST", header:{ "Content-Type":"application/x-www-form-urlencode" }, params:params, credentials:'include',//设置了这个之后 申请才会带上cookie }).then(res=>{ if(!res.OK){ throw Error(res.statusText) } return res.json() })}export {fetchPost}

Fetch mock数据

import FetchMock from 'fetch-mock'  FetchMock.mock('/login',(url,opts)=>{ const params = opts.params if(params.account === '17521077157'){ if(params.password === '12345'){   }else{ return { code:401,message:'明码谬误' } } }else{ return {code:400,message:'用户名谬误'} }}  )
