如何确保 JWT 验证发生在 React/Redux 路由器重定向之前？

Question

我正在使用 React/Redux、用于数据库的 Knex + Objection.Js + PostgreSQL 和用于 API 框架的 feathersjs 开发全栈 PERN 应用程序。因此，我也在前端使用 @feathersjs/client 及其身份验证包。我还使用 connected-react-router 作为我的路由。不幸的是，每当我尝试导航到受保护的路由时，负责设置用户状态的 "login" 请求（来自他们对服务器的 jwt 身份验证）在重定向将用户带到登录页面之前不会完成.

我正在通过调度一个动作来验证 React 应用程序 index.js 文件中的 jwt。

if (localStorage['feathers-jwt']) {
  try {
       store.dispatch(authActions.login({strategy: 'jwt', accessToken: localStorage.getItem('feathers-jwt')}));
  }
  catch (err){
      console.log('authenticate catch', err);
  }
}

该操作由 redux-saga 执行以下操作

export function* authSubmit(action) {
  console.log('received authSubmit');
  try {
    const data = yield call(loginApi, action);
    yield put({type: authTypes.LOGIN_SUCCESS, data});

  } catch (error) {
      console.log(error);
      yield put({type: authTypes.LOGIN_FAILURE, error})
  }
}

function loginApi(authParams) {
  return services.default.authenticate(authParams.payload)
}

这是我的 isAuthenticated 函数和配置对象：

const isAuthenticated =  connectedReduxRedirect({
  redirectPath: '/login',
  authenticatedSelector: state => state.auth.user !== null,
  redirectAction: routerActions.replace,
  wrapperDisplayName: 'UserIsAuthenticated'
});

这是应用于容器组件的 HOC

const Login = LoginContainer;
const Counter = isAuthenticated(CounterContainer);
const LoginSuccess = isAuthenticated(LoginSuccessContainer);

最后，这是渲染图

export default function (store, history) {
  ReactDOM.render(
    <Provider store={store}>
      <ConnectedRouter history={history}>
        <Switch>
          <Route exact={true} path="/" component={App}/>
          <Route path="/login" component={Login}/>
          <Route path="/counter" component={Counter}/>
          <Route path="/login-success" component={LoginSuccess}/>
          <Route component={NotFound} />
        </Switch>
      </ConnectedRouter>
    </Provider>,
    document.getElementById('root')
  );
}

我期望发生的事情，当登录并访问时，例如/counter是下面的

LOGIN_REQUEST 已触发操作
LOGIN_SUCCESS 动作已触发，用户已通过 JWT 认证
路由器发现 user.auth 对象不为空，因此用户是已验证
路由器允许无重定向导航

我看到的是以下内容（手动导航到 /counter 时）

@@INIT
auth/LOGIN_REQUEST[这个不错，loggingIn: true]
@@router/LOCATION_CHANGE

{
  type: '@@router/LOCATION_CHANGE',
  payload: {
    location: {
      pathname: '/counter',
      search: '',
      hash: ''
    },
    action: 'POP',
    isFirstRendering: true
  }
}

@@router_LOCATION_CHANGE[就是这个问题]

  type: '@@router/LOCATION_CHANGE',
  payload: {
    location: {
      pathname: '/login',
      hash: '',
      search: '?redirect=%2Fcounter',
      key: 'kdnf4l'
    },
    action: 'REPLACE',
    isFirstRendering: false
  }
}

用户导航到 /login，这会按照当前设计将用户注销。
LOGOUT_REQUEST -> LOGIN_SUCCESS -> LOCATION_CHANGE （到 /login-success）

再次强调，如有任何帮助，我将不胜感激，我可以根据需要提供任何其他信息。

谢谢！

解决方案

我今天通过查看身份验证包 feathers-reduxify-authentication 的功能解决了这个问题。在大多数情况下，重定向配置正确。

后端

authentication.js

注意多个策略，以及如何返回 context.result。这是 feathers-reduxify-authentication 正常工作所必需的。

module.exports = function (app) {
  const config = app.get('authentication');

  // Set up authentication with the secret
  app.configure(authentication(config));
  app.configure(jwt());
  app.configure(local(config.local));


  app.service('authentication').hooks({
    before: {
      create: [
        authentication.hooks.authenticate(config.strategies),
      ],
      remove: [
        authentication.hooks.authenticate('jwt')
      ]
    },
    after: {
      create: [
        context => {
          context.result.data = context.params.user;
          context.result.token = context.data.accessToken;
          delete context.result.data.password;
          return context;
        }
      ]
    }
  });
};

前端

src/feathers/index.js

这是根据eddystop的示例工程，升级到feathers 3.0+

import feathers from '@feathersjs/client';
import  io  from 'socket.io-client';
import reduxifyAuthentication from 'feathers-reduxify-authentication';
import reduxifyServices, { getServicesStatus } from 'feathers-redux';
import { mapServicePathsToNames, prioritizedListServices } from './feathersServices';
const hooks = require('@feathersjs/client');

const socket = io('http://localhost:3030');
const app = feathers()
  .configure(feathers.socketio(socket))
  .configure(hooks)
  .configure(feathers.authentication({
    storage: window.localStorage
  }));
export default app;

// Reduxify feathers-client.authentication
export const feathersAuthentication = reduxifyAuthentication(app,
  { authSelector: (state) => state.auth.user}
);
// Reduxify feathers services
export const feathersServices = reduxifyServices(app, mapServicePathsToNames);
export const getFeathersStatus =
  (servicesRootState, names = prioritizedListServices) =>
    getServicesStatus(servicesRootState, names);

中间件和存储。 src/state/configureStore

redux-saga 暂时移除，等我测试完再带回来

import { createBrowserHistory } from 'history';
import { createStore, applyMiddleware, compose } from "redux";
import { routerMiddleware  } from 'connected-react-router';
import createRootReducer from './ducks';
import promise  from 'redux-promise-middleware';
import reduxMulti from 'redux-multi';
import rootSaga from '../sagas';
import createSagaMiddleware from 'redux-saga';
export default function configureStore(initialState) {

    const composeEnhancer = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__
        || compose;

    const middlewares = [
        //sagaMiddleware,
        promise,
        reduxMulti,
        routerMiddleware(history)];

    const store = createStore(
        createRootReducer(history),
        initialState,
        composeEnhancer(
            applyMiddleware(
                ...middlewares
            )
        )
    );

    return store;
}

根减速器，src/state/ducks/index.js

import { combineReducers } from "redux";
import { connectRouter } from 'connected-react-router';
import { reducer as reduxFormReducer } from 'redux-form';
import {feathersAuthentication, feathersServices} from '../../feathers';
import counter from './counter';

const rootReducer = (history) => combineReducers({
    counter,
    router: connectRouter(history),
    users: feathersServices.users.reducer,
    auth: feathersAuthentication.reducer,
    form: reduxFormReducer, // reducers required by redux-form

});

export default rootReducer;
