A brief discussion on the encapsulation of axios in vue

The followingVue.js tutorial column will take you to understand the encapsulation of axios in vue. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

The encapsulation of axios in vue

The first step is to download axios first

cnpm install axios -S

The second step is to create A httpttp.js

import axios from 'axios';
import { Message } from 'element-ui';

axios.defaults.timeout = 5000;
axios.defaults.baseURL ='';


//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);
    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",
        query:{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)
         })
  })
}

The third step

Introduce

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;

in main.js and finally use it directly in the component

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

//其余的方法一样
