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)

如果你想重置一个减速机

例如

const initialState = { isLogged:假 ｝ //这将是你的行动 export const resetReducer = () => { 返回{ 类型:“重置” ｝ ｝ 导出默认值(state = initialState， { 类型, 有效载荷 }) => { 开关(类型){ //你的行动会报应到她头上 例“重置”: 返回{ initialState… ｝ ｝ ｝ //从你的前端 调度(resetReducer ())

npm install redux-reset
import reduxReset from 'redux-reset'
...
const enHanceCreateStore = compose(
    applyMiddleware(...),
    reduxReset()  // Will use 'RESET' as default action.type to trigger reset
  )(createStore)
const store = enHanceCreateStore(reducers)

为了将状态重置为初始状态，我编写了以下代码:

const appReducers = (state, action) =>
   combineReducers({ reducer1, reducer2, user })(
     action.type === "LOGOUT" ? undefined : state,
     action
);

简单回答一下丹·阿布拉莫夫的问题:

const rootReducer = combineReducers({
    auth: authReducer,
    ...formReducers,
    routing
});


export default (state, action) =>
  rootReducer(action.type === 'USER_LOGOUT' ? undefined : state, action);

除了Dan Abramov的回答之外，我们是否应该明确地将action设置为action = {type: '@@INIT'}以及state = undefined。采用上述动作方式，各减速器均返回初始状态。
