若要使用區域端點 API 操作 (物件層級或資料平面操作)，您可以使用 CreateSession API 操作來建立和管理工作階段，這些工作階段經過最佳化，可提供低延遲的資料請求授權。您也可以使用 CreateSession 來減少記錄量。若要確定在工作階段期間執行了哪些區域 API 操作，您可以將 CreateSession 日誌檔案中 responseElements 下的 accessKeyId 與其他區域 API 操作日誌檔案中的 accessKeyId 進行比對。如需詳細資訊，請參閱CreateSession 授權。

下列範例顯示 CloudTrail 日誌檔案範例，其中示範了 CreateSession 已驗證的 GetObject API 操作。
