作爲頁面發佈在facebook頁面上不是用戶

Question

我試圖以管理員身份發佈到facebook頁面。該帖子總是以用戶身份出現，而不是該帖子由頁面持有。

這裏是代碼，我參加了一個樣品上張貼的用戶牆，並添加manages_page權限和改變我/飼料PAGE_ID

Java文件：

public class MainFragment extends Fragment { 

private static final String TAG = "MainFragment";

    @Override 
    public void call(final Session session, final SessionState state,

     onSessionStateChange(session, state, exception); 
    }

顯然你不獲取頁面訪問令牌，並使用用戶訪問令牌代替。請求manage_pages權限是做正確的事，但事後你需要撥打電話到

/me/accounts 

拿到個人頁面的訪問令牌。然後，你必須使用此訪問令牌，使您的要求

{page_id}/feed
