Redux-persist继续加载

动机

我想保留页面刷新/重定向上的用户信息,但我也想在注销操作后清除它。


配置

const rootReducer = combineReducers({productsReducer, auth: accessReducer, usersReducer});

const persistConfig = {
    key: 'root',
    storage,
    whitelist: ['auth']
};

我只想将数据保留在accessReducer中,这就是为什么它被列入白名单。现在,我要以所有重置数据的方式处理注销。为此,我创建了logoutReducer:

注销减少器

export const logout = () => ({
    type: 'USER_LOGOUT'
});

const logoutReducer = (state, action) => {
    if(action.type = 'USER_LOGOUT'){
        state = undefined;
    }

    return rootReducer(state, action);
};

存储和持久化

const persistedReducer = persistReducer(persistConfig, logoutReducer);
export const store = createStore(persistedReducer, applyMiddleware(thunk));
export const persistor = persistStore(store);

问题

运行应用程序后,我将获得来自<Loader/>中的PersistGate的加载信息:

<Provider store={store}>
    <PersistGate loading={<Loader/>} persistor={persistor}>
        ...
    </PersistGate>
</Provider>

可能的原因

现在我想是因为我通过了logoutReducer,而该参考仅引用其他reducer,这就是配置失败的原因。如何保持用户信息并保持退出清除技巧?还有其他解决方案吗?任何帮助将不胜感激♥

答案

在研究此问题期间,我发现了this个问题,其中发帖人也有类似的问题。解决方案在这篇文章的最后一条评论中,即: react-reset 。 这是我对上述问题的解决方案:

const appReducer = combineReducers({productsReducer, auth: accessReducer, usersReducer});

const persistConfig = {
    key: 'root',
    storage,
    whitelist: ['auth']
};

const enHanceCreateStore = compose(
    applyMiddleware(thunk),
    reduxReset()
)(createStore);

const persistedReducer = persistReducer(persistConfig, appReducer);
export const store = enHanceCreateStore(persistedReducer);
export const persistor = persistStore(store);

然后,您只需执行redux-reset发出的注销调度操作:

store.dispatch({
  type: 'RESET'
})
