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
});

From a security perspective, the safest thing to do when logging a user out is to reset all persistent state (e.x. cookies, localStorage, IndexedDB, Web SQL, etc) and do a hard refresh of the page using window.location.reload(). It's possible a sloppy developer accidentally or intentionally stored some sensitive data on window, in the DOM, etc. Blowing away all persistent state and refreshing the browser is the only way to guarantee no information from the previous user is leaked to the next user.

(当然，作为共享计算机上的用户，你应该使用“私人浏览”模式，自己关闭浏览器窗口，使用“清除浏览数据”功能，等等，但作为开发人员，我们不能期望每个人都总是那么勤奋)

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
  })),

只需将注销链接清除会话并刷新页面。您的商店不需要额外的代码。当您想要完全重置状态时，页面刷新是一种简单且易于重复的处理方法。

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);
