请求时token过期自动刷新token操作

export default function request(url, options) {
  const token = localStorage.getItem('token');
  const defaultOptions = {
    headers: {

    .then(checkStatus)
    .catch(error => console.log(error));
}

  // 刷新token的函数,这需要添加一个开关，防止重复请求
  if(isRefreshing){
    refreshTokenRequst()
  }
  isRefreshing = false;
  // 这个Promise函数很关键
   const retryOriginalRequest = new Promise((resolve) => {
        addSubscriber(()=> {
          resolve(request(url, options))
        })
      });
