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。

 const reducer = (state = initialState, { type, payload }) => {

   switch (type) {
      case RESET_STORE: {
        state = initialState
      }
        break
   }

   return state
 }

你也可以触发一个动作，由所有或部分还原器处理，你想重置到初始存储。一个动作可以触发你整个状态的重置，或者只是适合你的一部分。我相信这是最简单、最可控的方法。

这种方法非常正确:销毁任何特定状态“NAME”以忽略并保留其他状态。

const rootReducer = (state, action) => {
    if (action.type === 'USER_LOGOUT') {
        state.NAME = undefined
    }
    return appReducer(state, action)
}

使用Redux，如果应用了以下解决方案，它假设我已经在所有的reducers(例如{user: {name, email}})中设置了initialState。在许多组件中，我检查这些嵌套的属性，所以有了这个修复，我防止我的渲染方法在耦合属性条件上被破坏(例如if state.user。如果上面提到的解决方案，电子邮件将抛出一个错误用户是未定义的)。

const appReducer = combineReducers({
  tabs,
  user
})

const initialState = appReducer({}, {})

const rootReducer = (state, action) => {
  if (action.type === 'LOG_OUT') {
    state = initialState
  }

  return appReducer(state, action)
}

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)

使用Redux Toolkit和/或Typescript:

const appReducer = combineReducers({
  /* your app’s top-level reducers */
});

const rootReducer = (
  state: ReturnType<typeof appReducer>,
  action: AnyAction
) => {
/* if you are using RTK, you can import your action and use it's type property instead of the literal definition of the action  */
  if (action.type === logout.type) {
    return appReducer(undefined, { type: undefined });
  }

  return appReducer(state, action);
};
