在我的google +頁面（.Net）中簡單插入（時刻）的錯誤

Question

晚安，

我嘗試添加參數作爲註釋，但無濟於事。 我得到了下面的代碼，但是現在的錯誤是現在...

ProtocolException as caught 
Error occurred while sending a direct message or getting the response. 

有人可以幫助我，因爲我幾乎以爲這是不可能的。

要編寫AppActivity，需要在配置Google+登錄按鈕時設置request-visible-actions參數。此參數指示您打算編寫哪個AppActivityType。您可以通過https://developers.google.com/+/web/app-activities/?hl=en或通過觀看Google+開發人員現場節目http://www.youtube.com/watch?v=cQC_EanIaUw#t=6m46s瞭解更多信息。
