使用 GoogleAdsService 回報串流
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
如要擷取 Google Ads API 實體和報表資料,請使用下列任一方法:
這兩種方法的主要差異如下:
SearchStream
對Search
Search
可以傳送多個分頁要求來下載完整報表,但 SearchStream
只會傳送單一要求,並與 Google Ads API 建立持續連線,不受報表大小影響。
如果是 SearchStream
,資料封包會立即開始下載,整個結果會快取在資料緩衝區中。您的程式碼可以開始讀取緩衝資料,不必等待整個串流完成。
視應用程式而定,SearchStream
可省去要求 Search
回應中每個網頁所需的網路往返時間,因此與分頁功能相比,SearchStream
可提升效能,尤其是在處理較大的報表時。
範例
這個範例會查看包含 100,000
個資料列的報表。下表列出這兩種方法在會計上的差異。

在大多數情況下,我們建議使用 SearchStream
,而非 Search
,原因如下:
頻率限制
兩種方法的每日上限都必須遵守開發人員權杖的標準限制和存取層級。無論結果是否分頁或串流,單一查詢或報表都會計為一項作業。

Your code can start reading the buffered data\nwithout having to wait for the entire stream to finish.\n\nBy eliminating the round-trip network time required to request each individual\npage of a `Search` response, depending on your app, `SearchStream` can offer\nimproved performance over paging, especially for bigger reports.\n\n### Example\n\nThis example looks at a report that consists of `100,000` rows. The following\ntable breaks down the accounting differences between the two methods.\n\n| | SearchStream | Search |\n| Page size | Not Applicable | 10,000 rows per page |\n| Number of API requests | 1 request | 10 requests |\n| Number of API responses | 1 continuous stream | 10 responses |\n|-------------------------|---------------------|----------------------|\n\n### Performance factors\n\nFor most use cases, we recommend `SearchStream` over `Search` for the following\nreasons:\n\n- For single page reports (under 10,000 rows): No significant performance\n differences between the two methods.\n\n- For multiple page reports: `SearchStream` is typically faster since multiple\n round trips are avoided, and reading or writing from disk cache is less of a\n factor.\n\n### Rate limits\n\nDaily limits for both methods adhere to the standard limits and [access\nlevels](/google-ads/api/docs/access-levels) of your developer token. A single query or report\nis counted as one operation regardless of the result being paged or streamed."]]
