vue中的axios封装

import axios from 'axios';

import { Message } from 'element-ui';

axios.defaults.timeout = 5000;
axios.defaults.headers = {'Content-Type': 'application/x-www-form-urlencoded'}

axios.defaults.withCredentials = true

//http request 拦截器
axios.interceptors.request.use(
  config => {
    // const token = getCookie('名称');注意使用的时候需要引入cookie方法，推荐js-cookie
    config.data = JSON.stringify(config.data);
    // 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)
  }
)

/**
 * 封装get方法
 * @param url
 * @param data
 * @returns {Promise}
 */

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

/**
 * 封装post请求
 * @param url
 * @param data
 * @returns {Promise}
 */

 export function post(url,data = {}){
   return new Promise((resolve,reject) => {
     axios.post(url,data)
          .then(response => {
            resolve(response.data);
          },err => {
            reject(err)
          })
   })
 }

 /**
 * 封装patch请求
 * @param url
 * @param data
 * @returns {Promise}
 */

export function patch(url,data = {}){
  return new Promise((resolve,reject) => {
    axios.patch(url,data)
         .then(response => {
           resolve(response.data);
         },err => {
           reject(err)
         })
  })
}

 /**
 * 封装put请求
 * @param url
 * @param data
 * @returns {Promise}
 */

export function put(url,data = {}){
  return new Promise((resolve,reject) => {
    axios.put(url,data)
         .then(response => {
           resolve(response.data);
         },err => {
           reject(err)
         })
  })
}

main.js全局引入

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

接口调用

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