oauthService.getAccessToken（）在angular-oauth2-oidc中返回null

下面给出了使用angular-oauth2-oidc使用AD FS验证angular SPA的代码

  initializeOAuthService(): void {

    this.oauthService.configure({
      redirectUri: window.location.origin + '/app/search',
      requireHttps: true,
      scope: 'openid profile email',
      responseType: 'id_token token',
      oidc: true,
      clientId: environment.adfsClientId,
      loginUrl: environment.adfsUrl + '/oauth2/authorize',
      issuer: environment.adfsUrl,
      logoutUrl:
        environment.adfsUrl +
        '/ls/?wa=wsignoutcleanup1.0&wreply=' +
        location.protocol +
        '//' +
        location.hostname +
        (location.port ? ':' + location.port : ''),
      postLogoutRedirectUri:
        location.protocol +
        '//' +
        location.hostname +
        (location.port ? ':' + location.port : ''),
    });

    this.oauthService.tokenValidationHandler = new JwksValidationHandler();
    this.oauthService.setStorage(localStorage);

    if (!this.oauthService.hasValidAccessToken()) {
      console.log('no access token available');
      this.oauthService
        .loadDiscoveryDocumentAndTryLogin()
        .then(() => {
          if (!this.oauthService.hasValidAccessToken()) {
            this.oauthService.initImplicitFlow();
          }
        })
        .catch((error) => {
          console.log(error);
        });
    }

    // this.oauthService.setupAutomaticSilentRefresh();
  }

我可以成功登录到应用程序，并且可以在URL中看到访问和id标记

但当我调用“oauthService.getAccessToken（）或”this.oauthService.getIdentityClaims（）”时，结果是null

谁能告诉我我错过了什么

注意：我已经从登录组件的构造函数调用了上述方法。登录页面和AD FS重定向到的页面不同
