angular - 在解析器中使用重定向时，Angular 2 解析器会导致无限循环

Question

我有以下调用 api 服务的解析器。根据我回来的结果，我想将用户重定向到特定屏幕：

@Injectable()
export class TenantStatusResolver implements Resolve<any> {

  tenantStatus: OnboardStatusEnum = OnboardStatusEnum.TenantyType;

  constructor(
    private _httpClient: HttpClient,
    private _router: Router) {
  }

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<any> | Promise<any> | any {

    if (this.tenantStatus === OnboardStatusEnum.Completed) {
      return;
    }

    return new Promise((resolve, reject) => {
      this._httpClient.get(environment.api.onboarding.tenantStatus).subscribe((response: TenantOnboardStatusDto) => {
        this.tenantStatus = response.onboardStatus;
        this._router.navigate(["/main/onboarding/tenant-type"]);
        resolve();
      }, reject);
    });

  }
}

在我的 main.module.ts 我有

const routes = [
    {
      path: '',
      resolve: {
        tenantStatus: TenantStatusResolver
      },
      children: [
        {
          path        : 'onboarding',
          loadChildren: './onboarding/onboarding.module#OnboardingModule',
          canLoad: [AuthenticationRouteGuard]
        },

问题是解析器陷入无限循环。这里有什么问题？
