在Facebook上發表評論

我想在成功登錄後使用以下代碼發表評論。在Facebook上發表評論

public void postOnWall(String msg) { 
     Log.d("Tests", "Testing graph API wall post"); 
     //byte[] by_new = msg.getBytes(); 
     try { 
       String response = mFacebook.request("me"); 
       Bundle parameters = new Bundle(); 
       parameters.putString("message", msg); 
       parameters.putString("description", "test test test"); 
       response = mFacebook.request("me/feed", parameters, 
         "GET"); 
       Log.d("Tests", "got response: " + response); 
       if (response == null || response.equals("") || 
         response.equals("false")) { 
        Log.v("Error", "Blank response"); 
       } 
     } catch(Exception e) { 
      e.printStackTrace(); 
     } 
    }

logcat的：

06-01 17:51:44.042: DEBUG/Tests(623): got response: {"data":[]}

但是，當我使用GET方法我接收到空白響應和當我用POST方法我接收到以下的反應。

對此行的評論String response = mFacebook.request（「me」）;並檢查它，因爲我已經回答 – Khan

@Akki謝謝，但現在回覆：06-01 18：33：46.452：調試/測試（843）：得到的迴應：{「error」：{「message」：「（＃200）用戶沒有授權應用程序執行此操作「，」type「：」OAuthException「，」code「：200}} –

試試這個，我認爲如u已經把「GET」，而不是「POST」

String response = facebook.request("me/feed", parameters,"POST");

我嘗試了GET和POST。使用POST錯誤發生在上面發佈。 –

對此行的評論String response = mFacebook.request（「me」）;而不是像我回答那樣檢查它 – Khan
