我得到25個結果列表postsList 我如何循環現在asgain下一個25個結果獲得下一個頁面，並在添加到postsList和循環一遍又一遍，直到沒有更多的結果？如何使用facebook api爲下一個25頁的結果循環？
我想要做的是每50分鐘自動刪除最後25個帖子。 在我項目的其他課上，我每分鐘都會自動發貼到我的牆上。 50分鐘後，我想刪除最後的25個帖子，所以我的牆上只有25個帖子。

海洋的權利，這是我的意思的邏輯。但是，我如何將它添加到FOR循環的代碼中，這樣它每次都會自動提高偏移量25，直到結果爲0，這樣我就不會再發布任何文章了？ –
您希望獲得之前的所有帖子嗎？這基本上可以是無限的，你確定這是你想要的嗎？解決方案是添加一個按鈕來加載下一頁。然後，只需使用表示您所在頁面的屬性（** offset **）即可。 – Oceans
這是一個非常動態的解決方案......但你是對的，獲得所有以前的帖子甚至可能讓你達到api限制，因爲這可能是很多電話。 – luschn
