This time I will bring you a detailed explanation of the steps for introducing vue-cli and configuring axios. What are the precautions for introducing vue-cli and configuring 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
