報表串流

透過集合功能整理內容 你可以依據偏好儲存及分類內容。

有三種方法可用來擷取實體,以及使用 Google Ads API 製作報表。

本指南主要著重於從 GoogleAdsService 串流資料。以下是三個資料擷取方法的高階差異:

GoogleAdsService.SearchStream Google 廣告服務.Search GET 要求
適合用於實際工作環境程式碼 No (僅供偵錯使用)
服務 GoogleAdsService GoogleAdsService 資源專屬服務 (例如 CampaignService)
情境 擷取物件和報表 擷取物件和報表 正在擷取物件
回應 GoogleAdsRow 個物件的串流 GoogleAdsRow 物件的頁面 一個物件 (例如 Campaign)
回應欄位 僅限查詢中指定的項目 僅限查詢中指定的項目 已填入所有欄位
每日使用時間上限 根據存取層級設定的每日上限 根據存取層級設定的每日上限 每日 1,000 個要求

雖然 Search 可傳送數個分頁要求來下載整份報表,但 SearchStream 會傳送一個要求,並開始與 Google Ads API 建立永久連線 (無論報表大小為何)。

SearchStream 而言,資料封包會立即下載,而資料緩衝區已快取整個結果。您的程式碼會開始讀取緩衝資料,而不必等待整個串流完成。

透過消除應用程式的Search回應中個別頁面要求所需的往返網路時間 (視應用程式而定),SearchStream 可提供比分頁更佳的效能 (特別是在大型報表中)。

範例

以包含 100,000 列的報表為例,下表說明這兩種方法的會計差異。

搜尋訊息串 搜尋
頁面大小 不適用 每頁 10,000 列
API 要求數量 1 項要求 10 個要求
API 回應數量 1 個連續串流 10 則回覆

效能因素

一般來說,我們建議將 SearchStream 設為 Search,原因如下:

  • 針對單頁報表 (少於 10,000 列):這兩種方法之間沒有顯著的效能差異。

  • 針對多個網頁報告:SearchStream 通常速度較快,因為能避免執行多次來回作業,而從磁碟快取讀取/寫入的因素較少。

頻率限制

上述兩種方法的每日上限均遵循開發人員權杖的標準限制和存取層級。無論結果是經過分頁或串流,單一查詢或報表都只會計為一次作業。
