Search Ads 360 Reporting API 支援透過 Search
方法分頁查詢結果,方法是在要求中指定 page_size
。這會將查詢的結果集拆分為多個回應,每個回應最多包含 page_size
物件。如果未指定 page_size
,系統會自動將頁面大小上限設為 10,000 列。
例如,使用以下查詢:
SELECT
ad_group.id,
ad_group_criterion.type,
ad_group_criterion.criterion_id,
ad_group_criterion.keyword.text,
ad_group_criterion.keyword.match_type
FROM ad_group_criterion
WHERE ad_group_criterion.type = KEYWORD
如果帳戶包含 50,000 個關鍵字,且 page_size
設為 1,000
,則結果集會在第一個回應中包含 1,000 個 SearchAdsRow
物件,以及一個 next_page_token
。如要擷取下一千列,只要以相同的頁面大小再次傳送要求,但請將要求的 page_token
更新為回應的 next_page_token
。後續要求中的 page_size
值可能每次都不同。
我們的用戶端程式庫會自動處理分頁作業。您只需逐一檢查回應的資料列。當目前頁面中的所有資料列都已傳回後,用戶端程式庫會自動為您擷取新的資料列頁面,直到整個資料集都已擷取為止。如果您使用 REST 而非 gRPC,則必須明確提出每個新頁面的請求。
Search Ads 360 Reporting API 會在內部快取整個資料集,因此後續要求的速度會比第一個要求快。視使用情況而定,您可以將 page_size
設為 1 到 10,000 之間的任何值。一般來說,為了提升整體效能,您應使用較大的 page_size
,因為這樣回應的往返次數會減少。
