问题描述

我正在使用 React/Redux、Knex + Objection.Js + PostgreSQL 为 DB 和 feathersjs 为 API 框架开发一个全栈 PERN 应用程序。因此，我@feathersjs/client也在前端及其身份验证包上使用。我也connected-react-router用于我的路由。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“登录”请求（从他们向服务器进行的 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index.js通过调度一个动作来验证反应应用程序文件中的 jwt。

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

动作被拾取redux-saga，执行以下动作

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isAuthenticated的配置对象函数：

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

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')
  );
}

例如，在登录和访问时，我期望发生/counter的情况如下

LOGIN_REQUEST 操作已触发
触发 LOGIN_SUCCESS 操作，用户通过 JWT 身份验证
路由器看到 user.auth 对象不为空，因此用户已通过身份验证
路由器允许导航而无需重定向

我看到的是以下内容（手动导航到时/counter）

@@在里面
auth/LOGIN_REQUEST [这很好，loggingIn: true]
@@router/LOCATION_CHANGE

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

@@router_LOCATION_CHANGE [这是问题]

  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，任何帮助将不胜感激，我可以根据需要提供任何其他内容。

谢谢！

解决方案

Solution

I was able to solve this today by taking a look at how the authentication package feathers-reduxify-authentication function. The redirect was, for the most part, configured correctly.

BACKEND

authentication.js

Note multiple strategies, and how the context.result is returned. This is necessary for feathers-reduxify-authentication to work properly.

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;
        }
      ]
    }
  });
};

FRONTEND

src/feathers/index.js

This is according to eddystop's example project, but upgraded to 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);

middleware and store. src/state/configureStore

redux-saga is temporarily removed, I'll be bringing it back once I finish testing

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;
}

root reducers, 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;
