我用以下代码工作

import axios from 'axios';
import config from '../../configuration.json';
import qs from 'qs';

const baseURL = config['baseUrl_local'];
let authTokenRequest;

/**
  * @description axios instance for ajax requests
*/

var client = axios.create({
baseURL: baseURL,
headers: {
    appID: 8,
    version: "1.1.0",
    empID: localStorage.getItem('empID'),
    token: localStorage.getItem('accessToken')
}
});

/**
 * @description this method calls a requestNewToken method to issue a 
 new token to the client
*/

 function getAuthToken() {
   if (!authTokenRequest) {
   authTokenRequest = requestNewToken();
   authTokenRequest.then(resetAuthTokenRequest, resetAuthTokenRequest);
 }
 return authTokenRequest;
 }

/**
  * @description this method requests the server to issue a new token, 
  the server response is updated in local storage accessToken
*/

function requestNewToken() {
  var newToken = request({
  method: "post",
  url: '/sign-in',
  data:  qs.stringify({
         "userName":localStorage.getItem('userName'),
         "password":localStorage.getItem('password')
         })  
  }).then((res)=>{
  if(res.status == "success"){
    localStorage.setItem('accessToken',res.data.accessToken);
    //if featureArray is present in response object, update the 
    featureArray in local storage
    if(res.data.features){
      localStorage.setItem(
      'featureArray',
     JSON.stringify(res.data.features));
    }
    client = axios.create({
     baseURL: baseURL,
     headers: {
          appID: 8,
          version: "1.1.0",
          empID: localStorage.getItem('empID'),
          token: localStorage.getItem('accessToken')
      }
   });
 } else {
  window.location = "/logout";
 }
});
 return newToken;
}

function resetAuthTokenRequest() {
  authTokenRequest = null;
 }

/**
  * @description if any of the API gets 401 status code, this method 
   calls getAuthToken method to renew accessToken
  * updates the error configuration and retries all failed requests 
  again
*/

client.interceptors.response.use(undefined, err => {
  const error = err.response;
  // if error is 401 
  if (error.status===401 && error.config && 
  !error.config.__isRetryRequest) {
  // request for a new token
  return getAuthToken().then(response => {
   // update the error config with new token
   error.config.__isRetryRequest = true;
   error.config.headers.token= localStorage.getItem("accessToken");
   return client(error.config);
  });
 } 
});

/**
 * @description wrapper for making ajax requests
 * @param {object} object with method,url,data etc.
*/

const request = function(options) {
  const onSuccess = function(response) {
    return response.data;
  }
 const onError = function(error) {
  //console.error('Request Failed:', error.config);
   if (error.response) {
  //console.error('Status:',  error.response.status);
  //console.error('Data:',    error.response.data);
  //console.error('Headers:', error.response.headers);
  } else {
  console.error('Error Message:', error.message);
  }
 return Promise.reject(error.response || error.message);
 }

return client(options)
        .then(onSuccess)
        .catch(onError);
        options
}

export default request;

[编辑]它的2019，这是相同的另一个实现。上面的解决方案很棒，但是不能用于多个失败的请求，反过来，它也会调用带有更新令牌的getToken。

 import axios from "axios";

 /* @internal */
 import config from "../config";
 import TokenService from "./token_service";

class Request {
    constructor() {
        this.baseURL = config.baseUrl;
        this.isRefreshing = false;
        this.failedRequests = [];
        this.tokenService = new TokenService();
        this.client = axios.create({
            baseURL: config.apiServerBaseUrl,
            headers: {
               clientSecret: this.clientSecret,
            },
        });
        this.beforeRequest = this.beforeRequest.bind(this);
        this.onRequestFailure = this.onRequestFailure.bind(this);
        this.processQueue = this.processQueue.bind(this);
        this.client.interceptors.request.use(this.beforeRequest);
        this.client.interceptors.response.use(this.onRequestSuccess, 
this.onRequestFailure);
}

beforeRequest(request) {
    const token = TokenService.getAccessToken();
    request.headers.Authorization = `Token ${token}`;
    return request;
}

static onRequestSuccess(response) {
    return response.data;
}

async onRequestFailure(err) {
    const { response } = err;
    if (response.status === 401 && err && err.config && !err.config.__isRetryRequest) {
        if (this.isRefreshing) {
            try {
                const token = await new Promise((resolve, reject) => {
                    this.failedRequests.push({ resolve, reject });
                });
                err.config.headers.Authorization = `Bearer ${token}`;
                return this.client(err.config);
            }
            catch (e) {
                return e;
            }
        }
        this.isRefreshing = true;
        err.config.__isRetryRequest = true;
        return new Promise((resolve, reject) => {
            this.tokenService.refreshAccessToken().then((token) => {
                this.tokenService.setAccessToken(token);
                err.config.headers.Authorization = `Bearer ${token}`;
                this.isRefreshing = false;
                this.processQueue(null, token);
                resolve(this.client(err.config));
            }).catch((e) => {
                this.processQueue(e, null);
                reject(err.response);
            });
        });
    }
    throw response;
}

processQueue(error, token = null) {
    this.failedRequests.forEach((prom) => {
        if (error) {
            prom.reject(error);
        } else {
            prom.resolve(token);
        }
       });
        this.failedRequests = [];
    }

}

const request = new Request();

export default request.client;
