使用 connect 与 react-redux 和 redux-persist答案

【问题描述】：

我的 react-redux 和 redux-persist 设置出现以下错误：

上述错误发生在组件中：在Connect(App)中（由 Route) in Route (由 withRouter(Connect(App))) 中创建在Router（由BrowserRouter创建）中的withRouter（Connect（App）） Provider中PersistGate中的BrowserRouter

我是这样设置的：

store.js

import {applyMiddleware, createStore} from 'redux';
import {persistStore,persistCombineReducers} from 'redux-persist';
import storage from 'redux-persist/es/storage' // default: localStorage if web, AsyncStorage if react-native

import { logger } from 'redux-logger';
import thunk from 'redux-thunk';
import promise from 'redux-promise-middleware';
import reducer from './reducers'

const middleware = applyMiddleware(promise(), thunk, logger);

const config = {
  key: 'root',
  storage,
};

const reducers = persistCombineReducers(config, {reducer});

export const configureStore = () => {
  const store = createStore(reducers, middleware);
  const persistor = persistStore(store);
  return { persistor, store };
};

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import {BrowserRouter} from 'react-router-dom';
import {Provider} from 'react-redux';
import Bootstrap from 'bootstrap/dist/css/bootstrap.css';
import './css/app.css';
import App from './containers/App';

import { PersistGate } from 'redux-persist/es/integration/react'
import configureStore from './store';
const { persistor, store } = configureStore()


ReactDOM.render(
  <Provider store={store} >
    <PersistGate persistor={persistor}>
    <BrowserRouter>
      <App/>
    </BrowserRouter>
  </PersistGate>
  </Provider>,
  document.getElementById('root')
);

App.js

import React from 'react'
import { withRouter, Switch, Route } from 'react-router-dom'
import { connect } from 'react-redux'
...
@withRouter
@connect((store) => {
  return {
    isAuthenticated: store.auth.isAuthenticated,
  };
})
export default class App extends React.Component {
  render() {
...
  }
}

更新 1

完整的控制台日志

更新 2

这是声明reducer的正确方法吗？没有 redux-persist 也能正常工作

authReducer.js

export default function reducer(state = {
  isAuthenticated: false
}, action) {
...
}

更新 3

REHYDRATE 控制台日志

更新 4

index.js（在 reducers 文件夹中）

import { combineReducers } from 'redux';
import user from './userReducer';
import auth from './authReducer';


export default combineReducers({
  user,
  auth
})

【问题讨论】：

你的 app.js 似乎被截断了或者什么的......
我更新了它，但我认为问题不在于缺少的代码..
也许它在控制台中指定了有关错误的更多详细信息？我想应该有第二条消息
@DanielKhoroshko 添加了完整日志
auth reducer 好像丢失了初始状态？

【解决方案1】：

所以问题是一个人不应该同时使用 combineReducers 和 persistCombineReducers。类似的情况可以在这里找到https://github.com/rt2zz/redux-persist/issues/516
