圖Facebook將不會檢索數據

我試圖從Facebook使用圖Facebook檢索數據，就像Profile Pic, Gender, Age, Name, ID & Link，我得到Facebook Profile Pic只成功，但其他不會檢索。請幫忙！圖Facebook將不會檢索數據

@Martijn彼得讓我看到重複的問題，它爲什麼標記爲重複。 –

您對多個問題發佈了相同的答案;你認爲你對自己問題的回答也回答了另一個問題，很明顯你感到自己的答案適用於兩者。我現在看到你的答案太薄而不能支持這個結論，我已經重新開放了這個結論。 –

將來，如果您能夠更詳細地回答您的問題，這將會很有幫助;就像在什麼版本中被棄用一樣。 –

就消失了棄用功能。
