创建和访问定期报告

您可以使用 Google Display & Video 360 界面或 API 创建并安排定期生成报告。例如，最终用户可以设置显示昨天的展示次数的每日报告，或显示总支出的每月报告。

创建定期生成的报表

在 Display & Video 360 报告界面中或使用 queries.create API 方法创建新的定期生成报告。如需详细了解 Display & Video 360 的报告功能以及如何创建新报告，请访问 Display & Video 360 支持网站。

您可以在创建报告时使用界面中的 Repeats 字段和 API 中的 schedule 字段安排定期生成报告。这些字段应设置为适当的时间间隔。

设置适当的字段后，此报告将按该时间表运行，随后生成的报告便可供下载。

访问定期生成的报告

定期生成的报告是作为简单的 CSV 文件生成的，会自动安全地存储在 Google Cloud Storage 中。但是，您无法直接访问包含这些文件的 Google Cloud Storage 存储分区。不过，您可以从 Display & Video 360 界面手动下载这些文件，也可以使用从 API 中获取的预授权网址以编程方式检索这些文件。

下面的示例展示了如何使用 API 下载报告文件。在此示例中，将 queries.reports.list 与 orderBy 参数搭配使用，以检索某个查询下的最新报告。然后，使用 Report.reportMetadata.googleCloudStoragePath 字段查找报告文件并将其内容下载到本地 CSV 文件中。
