将结果分页

Search Ads 360 Reporting API 支持通过 Search 方法对查询结果进行分页,方法是在请求中指定 page_size。这会将查询的结果集分为多个响应,其中每个响应最多可包含 page_size 个对象。如果未指定 page_size,系统会自动将其设置为页面大小上限(即 10,000 行)。

例如,使用以下查询:

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

如果您的账号包含 5 万个关键字,且 page_size 设置为 1,000,则结果集中第一个响应中将包含 1,000 个 SearchAdsRow 对象,以及一个 next_page_token。要检索下一批 1,000 行,只需使用相同的页面大小设置再发送一次请求即可,不过要将请求中的 page_token 更新为前一响应的 next_page_token。在后续的每次请求中,page_size 的值可能都会不同。

我们的客户端库会自动处理分页。您只需遍历响应的行即可。在返回当前页面中的所有行后,客户端库会代表您自动获取新的行页面,直到检索了整个数据集为止。如果使用 REST 取代 gRPC,那么您必须对每个新的页面明确地发出请求。

Search Ads 360 Reporting API 会在内部缓存整个数据集,因此后续请求的速度会比第一个请求快。根据您的用例,您可以将 page_size 设置为 1 到 10,000 之间的任何值。一般来说,为了加快整体的性能速度,您应该使用较大的 page_size,因为可减少响应中的往返次数。
