我有全球服务 userAuthService

用户身份验证服务:

  private identity = new BehaviorSubject(<Identity>{});
  public identity$ = this.identity.asObservable();

  private isValidToken = new BehaviorSubject<boolean>(false);
  public isValidToken$ = this.isValidToken.asObservable();

  constructor(
    private store: Store<AppState>,
    private router: Router,
    private apiService: ApiService,
  ) {
    this.store.select('tokens').subscribe((tokens: AuthToken) => {
      this.tokens = tokens;
      if (tokens && this.hasValidToken()) {
        this.isValidToken.next(true);
      } else {
        this.isValidToken.next(false);
      }
    });

    this.store.select('identity').subscribe((identity: any) => {
      if (identity.identity) {
        this.setIdentity(identity.identity);
      } 
    });
  }  

  setIdentity(identity: Identity) {
    this.identity.next(identity);
  }

  getIdentity() {
   this.store.dispatch(new identityActions.GetIdentityAction());
  }

  constructor(
    private store: Store<AppState>,
    private userAuthService: UserAuthService,
  ) {
    this.storeSub = this.store.select('tokens').subscribe((tokens: AuthToken) => {
      this.validToken = this.userAuthService.hasValidToken();
    });

    this.tokenSub = this.userAuthService.isValidToken$.subscribe((bool: boolean) => {
      this.validToken = bool;
      if (bool) {
        this.userAuthService.getIdentity();
      }
    });
  }

profile.component.ts文件:

  constructor(
    private userAuthService: UserAuthService
  ) {
    this.idenSub = this.userAuthService.identity$.subscribe((res: Identity) => {
      this.identity = res;
      console.log(this.identity);
    });
  }

profile.component.html文件:

<div>{{identity?.email}}</div>
