Twitter API с использованием Firebase: как получить твиттер accessToken для публикации от имени пользователя? Я уже вошел в систему

Question

Я использую firebase-UI для входа в систему с помощью твиттера, и теперь, как говорят документы, я должен получить токен доступа, используя метод private void handleTwitterSession(TwitterSession session). Вход работает нормально, но я не знаю, что отправить этой функции так называемому «сеансу». Как получить токен доступа от объекта mAb FirebaseAuth? ... Большое спасибо.

Answer 1

Я решил его использовать данные параметра firebase ui onActivityResult вместо того, чтобы пытаться использовать эту функцию handleTwitterSession, потому что firebase-ui уже обрабатывает этот loginWithCredentials, поэтому он будет избыточным. Изменение значения onActivityResult - вот что делает разницу в этом случае я размещаю рабочий код для справок:

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     if (requestCode == RC_SIGN_IN && resultCode == RESULT_OK) { 
      IdpResponse response = IdpResponse.fromResultIntent(data); 
      //twitter token 
      response.getIdpToken(); 
      //twitter secret 
      response.getIdpSecret(); 
     } 
    } 

Answer 2

Вы можете использовать setCallBack() получить TwitterSession

mLoginButton.setCallback(new Callback<TwitterSession>() { 
    @Override 
    public void success(Result<TwitterSession> result) { 
     Log.d(TAG, "twitterLogin:success" + result); 
     handleTwitterSession(result.data); 
    } 

    @Override 
    public void failure(TwitterException exception) { 
     Log.w(TAG, "twitterLogin:failure", exception); 
    } 
}); 

Взгляните на this вопрос тоже.
