您可以通过两种方法使用 Search Ads 360 Reporting API 检索实体和报告数据。

• SearchAds360Service.SearchStream
• SearchAds360Service.Search

本指南主要介绍如何处理来自 SearchAds360Service 的数据流。以下是这两种数据检索方法之间的概要区别：

SearchStream 与 Search

虽然 Search 可以发送多个分页请求来下载整个报告，但 SearchStream 只会发送一个请求，并与 Search Ads 360 Reporting API 建立持久连接（无论报告大小如何）。

对于 SearchStream，数据包会立即开始下载，整个结果会缓存在数据缓冲区中。您的代码可以开始读取缓冲数据，而无需等待整个数据流完成。

通过消除请求 Search 响应的每个单独页面所需的往返网络时间，SearchStream 的性能可以比分页更出色，具体取决于您的应用，尤其是对于较大的报告。

示例

例如，假设有一个包含 100,000 行的数据报告。下表详细说明了两种方法之间的会计差异。

性能因素

一般来说，我们建议您使用 SearchStream，而不是 Search，原因如下。

• 对于单页报告（少于 10,000 行）：这两种方法的性能没有明显差异。

• 对于多页报告：SearchStream 通常速度更快，因为它可以避免多次往返，并且从磁盘缓存读取/写入的影响较小。

速率限制

这两种方法的每日限制均遵循标准的 API 限制和配额。无论结果是分页还是流式传输，单个查询或报告都计为一次操作。
