vue用axios封装request

在这里插入代码片
``import axios from 'axios';
import { MessageBox, Message } from 'element-ui';
import store from '@/store';
import { getToken } from '@/utils/auth';
import { getBlobAsText } from '@/utils/commonFun';

// create an axios instance
const service = axios.create({
  baseURL: process.env.VUE_APP_BASE_API, // url = base url + request url
  // withCredentials: true, // send cookies when cross-domain requests
  timeout: 20000, // request timeout
});

// request interceptor
service.interceptors.request.use(
  config => {
    // do something before request is sent

    if (getToken()) {
      // let each request carry token
      // ['X-Token'] is a custom headers key
      // please modify it according to the actual situation
      config.headers['token'] = getToken();
    }
    return config;
  },
  error => {
    // do something with request error
    console.log(error); // for debug
    return Promise.reject(error);
  },
);

// response interceptor
service.interceptors.response.use(
  /**
   * If you want to get http information such as headers or status
   * Please return  response => response
   */

  /**
   * Determine the request status by custom code
   * Here is just an example
   * You can also judge the status by HTTP Status Code
   */
  async response => {
    try {
      let res = response.data;
      // blob类型错误返回需要手动转为json再做判断
      if (response.request.responseType === 'blob') {
        let responseJosn = {
          code: 0,
        };
        try {
          responseJosn = JSON.parse(await getBlobAsText(res));
          // eslint-disable-next-line no-empty
        } catch (error) {}

        res = {
          ...responseJosn,
          file: res,
        };
      }
      // if the custom code is not 20000, it is judged as an error.
      if (
        res.code === 0 ||
        (response.config.codes && response.config.codes.includes(String(res.code)))
      ) {

      } else {
        // 110: Token expired;
        if (res.code === 110) {
          // to re-login
          MessageBox.alert('登录超时', '系统提示', {
            confirmButtonText: '重新登录',
            type: 'warning',
          }).then(() => {
            store.dispatch('LogOut').then(() => {
              location.reload();
            });
          });
        } else {
          Message({
            message: res.message || res.result || res.msg || 'Error',
            type: 'error',
            duration: 5 * 1000,
          });
        }

      }
    } catch (error) {

    }
  },
  error => {
    console.log('err：1111111111111' + error); // for debug

      message: '网络错误',
      type: 'error',
      duration: 5 * 1000,
    });
    return Promise.reject(error);
  },
);

export default service;
