Angular 无法使用角度中的ngrx获取最新状态值

大家好，我是新来的。这些天来，我正在努力学习美国的国家管理。好吧，我试着遵循一些教程，但他们的一些代码已经贬值，所以我有点陷入了一个问题。即使在订阅ts文件后，我也无法获取该文件中的最新状态值

//Action File
import { Action } from '@ngrx/store';

export enum CategoriesActionTypes {
  LoadCategoriess = '[Categories] Load Categoriess',
  LoadCategoriessSuccess = '[Categories] Load Categoriess Success',
  LoadCategoriessFailure = '[Categories] Load Categoriess Failure',
}

export class LoadCategoriess implements Action {
  readonly type = CategoriesActionTypes.LoadCategoriess;
}

export class LoadCategoriessSuccess implements Action {
  readonly type = CategoriesActionTypes.LoadCategoriessSuccess;
  constructor(public payload: { data: any }) { }
}

export class LoadCategoriessFailure implements Action {
  readonly type = CategoriesActionTypes.LoadCategoriessFailure;
  constructor(public payload: { error: any }) { }
}

export type CategoriesActions = LoadCategoriess | LoadCategoriessSuccess | LoadCategoriessFailure;

//减速器锉

import { CategoriesActions, CategoriesActionTypes } from '../Actions/categories.actions';
import { Action } from '@ngrx/store';


export const categoriesFeatureKey = 'categoriesState';

export interface State {
categories :any,
error: any
}

export const initialState: State = {
  categories:[{name:'name'}],
  error :null,
};

export function reducer(state = initialState, action: CategoriesActions): State {
  
  switch (action.type) {
    case CategoriesActionTypes.LoadCategoriess:
    return{
      ...state
    }
    case CategoriesActionTypes.LoadCategoriessSuccess:
      // debugger
      console.log(action.payload.data);
      
      return {
        ...state,
        categories: action.payload.data,
        error: ''
      }

    case CategoriesActionTypes.LoadCategoriessFailure:
      return {
        ...state,
        categories: [],
        error: action.payload.error
      }
    default:
      return state;
  }
}

//效果文件

import { FrontserveiceService } from './../front/frontserveice.service';
import { Injectable } from '@angular/core';
import { Actions, Effect, createEffect, ofType } from '@ngrx/effects';

import { Observable, of } from 'rxjs';
import { Action } from '@ngrx/store';
import * as CategoriesActions from './../Actions/categories.actions';
import { mergeMap, map, catchError } from 'rxjs/operators';

@Injectable()
export class CategoriesEffects {



  constructor(private actions$: Actions,private service:FrontserveiceService) {}


  // @Effect()
  loadCategories$: Observable<any> = createEffect(() =>
  this.actions$.pipe(
    ofType(CategoriesActions.CategoriesActionTypes.LoadCategoriess),
    mergeMap(
      action => this.service.CategoryList({ image: true }).pipe(
        map(users => {
          return (new CategoriesActions.LoadCategoriessSuccess({ data: users }));
        }),
        catchError(err => of(new CategoriesActions.LoadCategoriessFailure({ error: err })))
      )
    )
  ));
  
}

//选择器

import { State } from './../Reducerss/categories.reducer';
import { createFeatureSelector, createSelector } from '@ngrx/store';

const getCategoryFeatureState = createFeatureSelector<State>('categoriesState');

export const getUsers = createSelector(
    getCategoryFeatureState,
    state => state.categories
)

export const getError = createSelector(
    getCategoryFeatureState,
    state => state.error
)

从“/../reducers/categories.reducer”导入{State}；
从'@ngrx/store'导入{createFeatureSelector，createSelector}；
常量getCategoryFeatureState=createFeatureSelector（'categoriesState'）；
export const getUsers=createSelector(
getCategoryFeatureState，
state=>state.categories
)
export const getError=createSelector(
getCategoryFeatureState，
state=>state.error
)

我现在拿到了。我试图访问一部分不允许访问的状态，这就是我无法访问订阅中状态的原因。

您可以共享您的订阅吗？另外，状态截图（redux开发工具）将有助于理解问题OK让我编辑我的问题，您可以共享您的选择代码吗？上传的选择代码

import { State } from './../Reducerss/categories.reducer';
