请求方向

<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
    <script>
          axios.interceptors.request.use(config=>{
            console.log("进入请求拦截器");
            console.log(config);
            return config; // 放行请求
          }),err=>{
              console.log("请求方向失败");
              console.log(err);
          }

          axios.get("url").then(ass=>{
              console.log(ass);
          })

    </script>

响应方向

<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
    <script>
          axios.interceptors.response.use(config=>{
            console.log("进入响应拦截器");
            return config.data; // 放行响应
          }),err=>{
              console.log("响应方向失败");
              console.log(err);
          }

封装到vue

	// 封装位置
    export function request(config){
        let newVar = axios.create((
            baseURL:"url",
            timeout:5000
        ));
        return newVar(config)
    }
    // 调用位置
    import {request} from './上面封装的位置'
    request({
        url:"关键字"
    }).then(res=>{
        console.log(res);
    })
