对我来说，最好的工作是设置initialState而不是state:

  const reducer = createReducer(initialState,
  on(proofActions.cleanAdditionalInsuredState, (state, action) => ({
    ...initialState
  })),

首先，在应用程序启动时，减速机的状态是新鲜的，并带有默认的InitialState。

我们必须添加一个动作，调用APP初始加载持续默认状态。

当注销应用程序时，我们可以简单地重新分配默认状态，reducer将像新的一样工作。

APP主容器

  componentDidMount() {   
    this.props.persistReducerState();
  }

主APP减速器

const appReducer = combineReducers({
  user: userStatusReducer,     
  analysis: analysisReducer,
  incentives: incentivesReducer
});

let defaultState = null;
export default (state, action) => {
  switch (action.type) {
    case appActions.ON_APP_LOAD:
      defaultState = defaultState || state;
      break;
    case userLoginActions.USER_LOGOUT:
      state = defaultState;
      return state;
    default:
      break;
  }
  return appReducer(state, action);
};

注销时调用重置状态的动作

function* logoutUser(action) {
  try {
    const response = yield call(UserLoginService.logout);
    yield put(LoginActions.logoutSuccess());
  } catch (error) {
    toast.error(error.message, {
      position: toast.POSITION.TOP_RIGHT
    });
  }
}

结合Dan Abramov的回答，Ryan Irilli的回答和Rob Moorman的回答，来解释保持路由器状态和初始化状态树中的其他所有东西，我最终得到了这样的答案:

const rootReducer = (state, action) => appReducer(action.type === LOGOUT ? {
    ...appReducer({}, {}),
    router: state && state.router || {}
  } : state, action);

丹·阿布拉莫夫的回答帮我破案了。然而，我遇到了一个案例，并不是整个州都需要清理。所以我是这样做的:

const combinedReducer = combineReducers({
    // my reducers 
});

const rootReducer = (state, action) => {
    if (action.type === RESET_REDUX_STATE) {
        // clear everything but keep the stuff we want to be preserved ..
        delete state.something;
        delete state.anotherThing;
    }
    return combinedReducer(state, action);
}

export default rootReducer;

在服务器中，有一个变量:global。isSsr = true 在每个reducer中，我都有一个const: initialState 要重置存储中的数据，我对每个Reducer执行以下操作:

appReducer.js的例子:

 const initialState = {
    auth: {},
    theme: {},
    sidebar: {},
    lsFanpage: {},
    lsChatApp: {},
    appSelected: {},
};

export default function (state = initialState, action) {
    if (typeof isSsr!=="undefined" && isSsr) { //<== using global.isSsr = true
        state = {...initialState};//<= important "will reset the data every time there is a request from the client to the server"
    }
    switch (action.type) {
        //...other code case here
        default: {
            return state;
        }
    }
}

最后在服务器的路由器上:

router.get('*', (req, res) => {
        store.dispatch({type:'reset-all-blabla'});//<= unlike any action.type // i use Math.random()
        // code ....render ssr here
});

onLogout () { this.props.history.push(' /登录');//发送用户到登录页面 window.location.reload ();//刷新页面 ｝
