axios

Axios 是一个基于 promise 的 HTTP 库，可以用在浏览器和 node.js 中。 axios文档

安装依赖

                npm install axios

                npm install vue-axios

main.js

import Vue from 'vue'
import App from './App.vue'
//elementUI
import './plugins/element.js'
import {  Message } from 'element-ui'
// import {  MessageBox } from 'element-ui'
import router from './router'

import axios from 'axios'
import VueAxios from 'vue-axios'


Vue.config.productionTip = false

axios.defaults.baseURL = 'http://123.com';

//添加请求时拦截器
axios.interceptors.request.use(config=>{
  //设置请求头为 表单提交头
  config.headers['Content-Type'] = "application/x-www-form-urlencoded"

  //设置提交数据为form表单格式
  let formData = new FormData()

  formData.append('p',JSON.stringify(config.data))

  config.data = formData
  
  console.log(config)

  return config
},err=>{
  return Promise.reject(err)
})

// 添加响应时拦截器
axios.interceptors.response.use(res=>{
  if(res.data.code == 200){
    return res
  }else{
    Message({type:'error',message:res.data.msg})
    return res
  }
  
},err=>{
  console.log(err)
})

//把axios注册到vue
Vue.use(VueAxios,axios)

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')
