1.axios.js文件

import axios from 'axios'
import { Loading, Message } from 'element-ui'// 引入Loading服务
// 创建 axios 实例
const service = axios.create({

})
// 开始加载动画
let loading
function startLoading() {
  loading = Loading.service({
    lock: true, // 是否锁定
    text: '正在交互...', // 加载中需要显示的文字
    background: 'rgba(0,0,0,.7)'// 背景颜色
  })
}
// 结束加载动画
function endLoading() {
  loading.close()
}
// request interceptor
service.interceptors.request.use(config => {
  var tokenjava = localStorage.getItem('tokenjava')
  var token = localStorage.getItem('token')
  startLoading()
  // alert('qingqiu')
  if (token) {
    config.headers[ 'api_key' ] = token // 让每个请求携带自定义 token 请根据实际情况自行修改
  }
  if (tokenjava) {
    config.headers[ 'api_key' ] = tokenjava // 让每个请求携带自定义 token 请根据实际情况自行修改
  }
  // if (token) {
  //   config.headers[ 'api_key' ] = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhdWQiOiJ7XCJMb2dpblRpbWVcIjpcIjIwMjEtMDEtMjggMTY6MTI6NDFcIixcIk9pZFwiOlwiMDAwMDAwMDAtMDAwMC0wMDAwLTAwMDAtMDAwMDAwMDAwMDAxXCJ9In0.HLCV0r7KP3rOpyWbLuvGYXo1uaAPQ_-lON03QWxoMAA'
  // }
  // if (tokenjava) {
  //   config.headers[ 'api_key' ] = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhdWQiOiJ7XCJMb2dpblRpbWVcIjpcIjIwMjEtMDEtMjggMTY6MTI6NDFcIixcIk9pZFwiOlwiMDAwMDAwMDAtMDAwMC0wMDAwLTAwMDAtMDAwMDAwMDAwMDAxXCJ9In0.HLCV0r7KP3rOpyWbLuvGYXo1uaAPQ_-lON03QWxoMAA'
  // }
  return config
}, (error) => {
  return Promise.reject(error)
})
// 相应拦截
service.interceptors.response.use(response => {
  // alert('end')
  endLoading()// 结束加载动画
  return response // 结束时把response return回去
}, error => {
  // 错误提醒
  endLoading()// 如果错误也结束动画
  Message.error(error.response.data)
  return Promise.reject(error)
})
export { service as axios }

2.写post、get接口

@/api/api.js

import { axios } from './axios'
const base = 'http://xxx.xxx.x.xxx:xxxx/'
const base3 = window.ApiConfig.base
export const getMenuList = params => { return axios.get(`${base}api/System/PortalMenu_GetAllData`, { params: params }) }
export const addPaperType = params => { return axios.post(`${base}api/System/PortalMenu_SaveData`, params).then(res => res.data) }

3.调用接口

<script>
import { getMenuList } from '@/api/api'
export default {
	...
	methods: {
		initData(){
			getMenuList().then(res=>{...})
		}
	}
	...
}
</script>
