Twitter的API：我如何獲得嘰嘰喳喳的accessToken張貼在代表用戶的？我已經登錄成功

Question

我使用火力的UI與Twitter登錄，現在作爲文檔說我得使用方法private void handleTwitterSession(TwitterSession session)訪問令牌。登錄工作正常，但我不知道發送給該功能的所謂的「會話」的內容。我如何從FirebaseAuth毛特對象??訪問令牌......非常感謝你。到文檔的鏈接是這個https://firebase.google.com/docs/auth/android/twitter-login

Answer 1

我解決它通過使用火力UI onActivityResult參數數據，而不是嘗試使用handleTwitterSession功能，導致火力的UI已經處理該loginWithCredentials所以這將是多餘.....改變onActivityResult是什麼讓差異在這種情況下，我張貼工作代碼以供將來參考：

@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

您可以使用setCallBack()得到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); 
    } 
}); 

看看this問題也。
