How to use vue-cli to introduce and configure axios

This time I will show you how to use vue-cli to introduce and configure axios, and what are the precautions for using vue-cli to introduce and configure axios. The following is a practical case, let's take a look.

1. npm install axios, install it in the file root directory, the instructions are as follows

npm install axios --save-dev

2. Modify the prototype Chain, introduce axios in main.js

import axios from 'axios'

Then rewrite axios as the prototype attribute of Vue,

Vue.prototype.$http=axios

In this way, the $http command can be called in the methods of each component to complete the data request

3. Use in the component

methods: { 
   get(){ 
    this.$http({ 
     method:'get', 
     url:'/url', 
     data:{} 
    }).then(function(res){ 
     console.log(res) 
    }).catch(function(err){ 
     console.log(err) 
    }) 
     
    this.$http.get('/url').then(function(res){ 
     console.log(res) 
    }).catch(function(err){ 
     console.log(err) 
    }) 
   }    
}

The following will introduce how to configure axios with vue-cli

1.

npm install axios --save

2.

npm install @type/axios --save-dev(使用ts编写的需要此声明文件，升级的axios好像不需要了，已经自带)

3.

In the src directory Add the axios.ts file below, content:

import axios from 'axios'
import {Notification} from 'element-ui'
import store from './store/index'
import buildconf from '../config/build.rootpath.js'
axios.defaults.withCredentials = true;
axios.defaults.baseURL = buildconf.serverUrl
// axios.defaults.baseURL = 'http://gsblackwidow.chinacloudsites.cn/'
axios.interceptors.request.use(function(config) {
 // document.getElementById('g-loader').style.display = 'flex'
 store.commit('requestModify', 1)
 return config;
}, function(error){
 return Promise.reject(error)
})
axios.interceptors.response.use(function(response){
 store.commit('requestModify', -1)
 // document.getElementById('g-loader').style.display = 'none' 
 return response.data;
}, function(error){
 store.commit('requestModify', -1) 
 // document.getElementById('g-loader').style.display = 'none'  
 if(error.response.status === 401){
  Notification({
   title: '权限无效',
   message: '您的用户信息已经失效, 请重新登录',
   type: 'warning',
   offset: 48
  });
  window.location.href = '/#/login'
 }else{
  Notification({
   title: '请求错误',
   message: `${error.response.status} \n ${error.config.url}`,
   type: 'error',
   offset: 48,
  })
 }
 return Promise.reject(error)
})
export default axios

4.

Create a new vue.d.ts file in the types folder, content:

import {AxiosStatic, AxiosInstance } from 'axios'
declare module 'vue/types/vue' {
 interface Vue {
  $axios: AxiosStatic;
 }
}

This way you can Axios is used in the module through this.$axios

Among them, axios:

1. Build.rootpath.js content:

var path = require('path')
var rootpath = path.resolve(dirname, '../dist')
module.exports = rootpath

2. Store is a vuex file , so you need to install vuex in advance
