我想列出使用Azure服務管理REST API的所有託管服務。 msdn hlep解釋了列出託管服務的一種方法。我附上了msdn中給出的示例代碼。應使用哪種拇指列印來列出使用Windows azure管理API的託管服務
在代碼中，他們使用了Version，Thumbprint和SubscriptionId。
在windows azure門戶中，我們可以看到一個subcription有一個subcription Id。並且證書有一個指紋。在一個subcription中可能有許多託管服務，所以許多證書也是如此。那麼以下代碼提到的指紋是什麼？ 是否應該使用所有訂閱的指紋進行檢查，以列出所有託管服務的訂閱內容。
爲什麼我們不能使用subcriptionId來獲得所有的託管服務（是不是安全的？）還是有一個通用的證書（所以有一個指紋）的一個subcription？
請指導我，
謝謝。
