我需要发布用户信息，但是我丢失了刷新信息。如何设置 isAuthenticated变量，我们在刷新时不会失去价值吗？ 也许您无需查看大部分代码，只是告诉我如何立即修复它 您需要的一部分我的代码：

组件：

  getState: Observable<any>;
  isAuthenticated: false;
  user = null;
  errorMessage = null;
  globalisAuthenticated = null;
  constructor(public dialog: MatDialog,private store: Store<AppState>) {
    this.getState = this.store.select(selectAuthState);
   }
  ngOnInit() {
    this.getState.subscribe((state) => {
      this.isAuthenticated = state.isAuthenticated;
      this.user = state.user;
      this.errorMessage = state.errorMessage;
      // console.log("is",this.isAuthenticated)
      localStorage.setItem("isAuthenticated",state.isAuthenticated);
    });

减速器：

export interface State {
  // is a user authenticated?
  isAuthenticated: boolean;
  // if authenticated,there should be a user object
  user: User | null;
  // error message
  errorMessage: string | null;
}

export const initialState: State = {
  isAuthenticated: false,user: null,errorMessage: null
};

    export function reducer(state = initialState,action: All): State {
      switch (action.type) {
        case AuthactionTypes.LOGIN_SUCCESS: {
          return {
            ...state,isAuthenticated: true,user: {
              token: action.payload.token,email: action.payload.email
            },errorMessage: null
          };
        }
        case AuthactionTypes.LOGIN_FAILURE: {
          return {
            ...state,errorMessage: 'Incorrect email and/or password.'
          };
        }
        default: {
          return state;
        }
      }
    }

效果：

  @Effect()
LogIn: Observable<any> = this.actions
  .ofType(AuthactionTypes.LOGIN)
  .map((action: LogIn) => action.payload)
  .switchMap(payload => {
    return this.authService.logIn(payload.email,payload.password)
      .map((user) => {
        console.log(user);
        return new LogInSuccess({token: user.token,email: payload.email});
      })
      .catch((error) => {
        console.log(error);
        return Observable.of(new LogInFailure({ error: error }));
      });
  });

  @Effect({ dispatch: false })
LogInSuccess: Observable<any> = this.actions.pipe(
  ofType(AuthactionTypes.LOGIN_SUCCESS),tap((user) => {
    console.log("User",user);
    localStorage.setItem('token',user.payload.token);
    this.snackBar.open("Uspesno ste ste prijavili.",null,{
      duration: 5000,verticalPosition: 'bottom',horizontalPosition: 'right'
   });
  })
);

状态：

export interface AppState {
  authState: auth.State;
}

export const reducers = {
  auth: auth.reducer
};

export const selectAuthState = createFeatureSelector<AppState>('auth');

您能告诉我一种避免刷新时丢失数据的方法吗？ 如果您需要更多信息，请问我。 现在一切正常。但是当我刷新时，我丢失了所有东西，但令牌在本地存储中。

UPDATE UPDATE UPDATE 我被添加了，但再次没有工作

  import { StoreModule,actionReducerMap,actionReducer,MetaReducer } from '@ngrx/store';
  import { localStorageSync } from 'ngrx-store-localstorage';
  import { reducers } from './reducers';


  // const reducers: actionReducerMap<IState> = {todos,visibilityFilter};

  export function localStorageSyncReducer(reducer: actionReducer<any>): actionReducer<any> {
    return localStorageSync({keys: ['todos']})(reducer);
  }
  const metaReducers: Array<MetaReducer<any,any>> = [localStorageSyncReducer];
