loading效果

1.导入loading组件

import {Loading} from 'element-ui'

2.main.js 声明请求拦截与响应拦截

let loadingInstance = null
axios.interceptors.request.use(config =>{
    //展示loading效果
    loadingInstance = Loading.service({fullscreen:true})
    return config
})
​
//声明响应拦截
axios.interceptors.response.use(response =>{
//隐藏Loading效果
loadingInstance.close()
return response
})
