Переадресация входа в Auth0 на страницу продолжает загружаться при использовании Firefox в качестве браузера - PullRequest

/ 30 марта 2020

Я использую логин Auth0, который обрабатывает логин для моей платформы после входа в систему, перенаправляет вас на платформу. С chrome это работает отлично, но в Firefox происходит перезагрузка страницы перенаправления. Я использовал стандартный код auth0 для реализации логики c на моей странице. Я не уверен, что идет не так, и даже где начать искать решение? Кто-нибудь когда-нибудь сталкивался с такой же ошибкой и может помочь мне исправить проблему, а также объяснить, что происходит?

файл auth.ts:

export class AuthService {
  // Create an observable of Auth0 instance of client
  auth0Client$ = (from(
    createAuth0Client({
      domain: authConfig.domain,
      client_id: authConfig.clientId,
      redirect_uri: `${window.location.origin}`,
      audience: authConfig.audience,
    })
  ) as Observable<Auth0Client>).pipe(
    shareReplay(1), // Every subscription receives the same shared value
    catchError(err => throwError(err))
  );

  // Manage Acces Token
  // Observable method to retrieve access token and make it available for use in application
  getTokenSilently$(options?): Observable<string> {

      concatMap((client: Auth0Client) => from(client.getTokenSilently(options)))
    );
  }

  // Define observables for SDK methods that return promises by default
  // For each Auth0 SDK method, first ensure the client instance is ready
  // concatMap: Using the client instance, call SDK method; SDK returns a promise
  // from: Convert that resulting promise into an observable

        }
        // If not authenticated, return stream that emits 'false'
        return of(loggedIn);
      })
