我正在开发一个服务类来创建一个 Axios 实例（在 React Native 中），我在其中使用一些拦截器来注入 JWT 令牌以针对 API 进行身份验证。

当应用检测到access token过期时，自动使用refresh token来同时请求新的令牌和新的刷新令牌。

问题是刷新令牌由于不活动而过期。

当刷新令牌过期时，我想将用户重定向到登录视图组件。

考虑到服务类是无状态的并且不关心它是从哪个组件调用的，我需要做什么才能重定向到我的登录视图组件？

这是我到目前为止所拥有的：


//API.js

import axios from 'axios';
import TokenStorage from './TokenStorage';

const API = axios.create({
    responseType: 'json',
});

...

API.interceptors.response.use((response) => {
    // Return a successful response back to the calling service
    return response;
}, (error) => {

    // Return any error which is not due to authentication back to the calling service
    ...

    // Logout user if token refresh didn't work or user is disabled
    if (error.config.url === '/tokens/refresh/' || error.response.data.code === 'access_invalid') {

        TokenStorage.cleanStorage();

        // TODO - Redirect to the "/login" route [Login View Component]

        return new Promise((resolve, reject) => {
            reject(error);
        });
    } else if (error.config.url === '/tokens/') {
        // Reject if user credentials are wrong
        return new Promise((resolve, reject) => {
            reject(error);
        });
    }

    // Try request again with new token
    ...

});

export default API;

环境：

"axios": "^0.19.0",
"react": "16.9.0",
"react-native": "0.61.2",
"react-router-native": "^5.1.2"

PS：这是一个与此非常相似的问题，但我需要一个使用 React Router Native 的解决方案。

编辑1：

我已经尝试使用以下"history": "^4.10.1"软件包，但没有成功：


// API.js

import {createMemoryHistory} from 'history';

const history = createMemoryHistory();

...
// Logout user if token refresh didn't work or user is disabled
    if (error.config.url === '/tokens/refresh/' || error.response.data.code === 'access_invalid') {

        TokenStorage.cleanStorage();

        history.push('/login'); // This don't work!

        return new Promise((resolve, reject) => {
            reject(error);
        });
    } else if (error.config.url === '/tokens/') {
        // Reject if user credentials are wrong
        return new Promise((resolve, reject) => {
            reject(error);
        });
    }

没有 Redux

//EventPublisher.js    
export default class EventPublisher {
  static instance;
  listeners = {};

  constructor(validEvents){
    validEvents.forEach(ve=>{
      this.listeners[ve] = []
    })
  }

  subscribe(event, listener){
    if(!this.listeners[event]) throw 'Invalid event'
    this.listeners[event].push(listener)
    return ()=>{
      this.listeners[event].remove(listener)
    }
  }

  publish(event){
    this.listeners[event].forEach(l=>l())
  }
}

在您的顶级组件中

componentDidMount(){
  EventPublisher.instance = new EventPublisher([
    'REFRESH_TOKEN',
  ])
  this.cancelEventSubscription = EventPublisher.instance.subscribe('REFRESH_TOKEN', ()=>{
    //Logic of react router native to navigate to LoginScreen
  })
}
componentWillUnmount(){
  this.cancelEventSubscription()
}

在 axios

if (error.config.url === '/tokens/refresh/' || error.response.data.code === 'access_invalid') {

        TokenStorage.cleanStorage();

        // TODO - Redirect to the "/login" route [Login View Component]
        EventPublisher.instance.publish('REFRESH_TOKEN')

        return new Promise((resolve, reject) => {
            reject(error);
        });
    } else if (error.config.url === '/tokens/') {
        // Reject if user credentials are wrong
        return new Promise((resolve, reject) => {
            reject(error);
        });
    }
