vue中axios的封装 vue中axios的封装问题(简易版拦截,get,post)

npm install axios --save

import axios from 'axios';
axios.defaults.timeout = 5000;
axios.defaults.baseURL ='';
//http request 拦截器
axios.interceptors.request.use(
 config => {
  // const token = getCookie('名称');
  config.data = JSON.stringify(config.data);
  config.headers = {
   'Content-Type':'application/x-www-form-urlencoded'
  }
  // if(token){
  //  config.params = {'token':token}
  // }
  return config;
 },
 error => {
  return Promise.reject(err);
 }
);
//http response 拦截器
axios.interceptors.response.use(
 response => {
  if(response.data.errCode ==2){
   router.push({
    path:"/login",
    querry:{redirect:router.currentRoute.fullPath}//从哪个页面跳转
   })
  }
  return response;
 },
 error => {
  return Promise.reject(error)
 }
)
/**

export function fetch(url,params={}){
 return new Promise((resolve,reject) => {
  axios.get(url,{
   params:params
  })
  .then(response => {
   resolve(response.data);
  })
  .catch(err => {
   reject(err)

 })
}
/**

     },err => {

     })
  })
 }

import {post,get} from './utils/http'
//定义全局变量
Vue.prototype.$post=post;
Vue.prototype.$get=get;

mounted(){
  this.$post('/api/v2/movie/top250')
   .then((response) => {
    console.log(response)
   })
 },
