Question

场景是用户相关的详细信息存储在一个减速器中。当用户 A 注销设备而用户 B 登录设备时，数据将被擦除，新用户数据将存储在减速器中。但是当应用程序关闭并从退出状态启动时，用户A的数据从persist中存储到reducer中。

我的商店配置代码如下：

import {createStore, compose, applyMiddleware} from 'redux';
import {persistStore, persistCombineReducers} from 'redux-persist';
import AsyncStorage from '@react-native-community/async-storage';
import {createLogger} from 'redux-logger';
import createSagaMiddleware from 'redux-saga';

import rootReducers from '../reducers'; // where reducers is a object of reducers
import sagas from '../sagas';

const config = {
  key: 'root',
  storage: AsyncStorage,
  blacklist: ['loadingReducer'],
  debug: true, //to get useful logging
};

const middleware = [];
const sagaMiddleware = createSagaMiddleware();

middleware.push(sagaMiddleware);

if (__DEV__) {
  middleware.push(createLogger());
}

const reducers = persistCombineReducers(config, rootReducers);

const rootReducer = (state, action) => {
  if (action.type === 'LOG_OUT') {
    return reducers(undefined, action);
  }
  return reducers(state, action);
};

const enhancers = [applyMiddleware(...middleware)];

const persistConfig = {enhancers};
const store = createStore(rootReducer, undefined, compose(...enhancers));
const persistor = persistStore(store, persistConfig, () => {
  //   console.log('Test', store.getState());
});
const configureStore = () => {
  return {persistor, store};
};

sagaMiddleware.run(sagas);

export default configureStore;

我尝试在用户尝试使用 AsyncStorage.removeItem('persist:root') 时使用 LOG_OUT ，但没有改变。旧数据即使应该被覆盖也被持久化。

知道是什么造成了这种奇怪的情况吗？？
