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);

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);
};

下面的解决方案对我很有效。

我添加了重置状态功能到元还原器。关键在于使用

return reducer(undefined, action);

将所有减速器设置为初始状态。返回undefined反而会导致错误，因为存储的结构已经被破坏。

/还原剂index.ts

export function resetState(reducer: ActionReducer<State>): ActionReducer<State> {
  return function (state: State, action: Action): State {

    switch (action.type) {
      case AuthActionTypes.Logout: {
        return reducer(undefined, action);
      }
      default: {
        return reducer(state, action);
      }
    }
  };
}

export const metaReducers: MetaReducer<State>[] = [ resetState ];

app.module.ts

import { StoreModule } from '@ngrx/store';
import { metaReducers, reducers } from './reducers';

@NgModule({
  imports: [
    StoreModule.forRoot(reducers, { metaReducers })
  ]
})
export class AppModule {}

一种方法是在应用程序中编写一个根减速器。

根减速机通常会将处理操作委托给combineReducers()生成的减速机。但是，无论何时它接收到USER_LOGOUT操作，它都会再次返回初始状态。

例如，如果你的根减速器是这样的:

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

你可以将它重命名为appReducer，并编写一个新的rootReducer委托给它:

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

const rootReducer = (state, action) => {
  return appReducer(state, action)
}

现在我们只需要教新的rootReducer返回初始状态以响应USER_LOGOUT操作。如我们所知，无论操作如何，当调用以undefined作为第一个参数时，约简器都应该返回初始状态。让我们用这个事实来有条件地剥离累积状态，当我们把它传递给appReducer:

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

  return appReducer(state, action)
}

现在，每当USER_LOGOUT触发时，所有减约器都将重新初始化。它们还可以返回与初始值不同的值，因为它们可以检查动作。也要打字。

重申一下，完整的新代码是这样的:

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

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

  return appReducer(state, action)
}

如果使用redux-persist，可能还需要清理存储空间。Redux-persist将您的状态副本保存在存储引擎中，刷新时将从那里加载状态副本。

首先，您需要导入适当的存储引擎，然后在将其设置为undefined并清除每个存储状态键之前解析状态。

const rootReducer = (state, action) => {
    if (action.type === SIGNOUT_REQUEST) {
        // for all keys defined in your persistConfig(s)
        storage.removeItem('persist:root')
        // storage.removeItem('persist:otherKey')

        return appReducer(undefined, action);
    }
    return appReducer(state, action);
};

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
);

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
    });
  }
}
