axios在elecrton请求超时处理办法

自己开发的一款elecron批量上传商品工具，在使用的过程中，会偶尔出现请求超时问题，无法获取到数据。

import axios from 'axios'
import { Message } from 'element-ui'
const serves = axios.create({
  baseURL: process.env.BASE_API,
  timeout: 3000
})

// 设置请求次数，请求间隔
serves.defaults.retry = 4;
serves.defaults.retryDelay = 800;

axios.interceptors.response.use(undefined, function axiosRetryInterceptor(err) {
  var config = err.config;
  // If config does not exist or the retry option is not set, reject
  if (!config || !config.retry) return Promise.reject(err);

  // Set the variable for keeping track of the retry count
  config.__retryCount = config.__retryCount || 0;

  // Check if we've maxed out the total number of retries
  if (config.__retryCount >= config.retry) {
    // Reject with the error
    Message.error('网络请求超时，请稍后再试')
    return Promise.reject(err);
  }

  // Increase the retry count
  config.__retryCount += 1;

  // Create new promise to handle exponential backoff
  var backoff = new Promise(function(resolve) {
    setTimeout(function() {
      resolve();
    }, config.retryDelay || 1);
  });

  // Return the promise in which recalls axios to retry the request
  return backoff.then(function() {
    return axios(config);
  });
});


// 设置请求发送之前的拦截器
serves.interceptors.request.use(config => {
  config.headers.action = localStorage.getItem('name')
  return config
}, err => Promise.reject(err))

// 将serves抛出去
export default serves
