ArcGIS Enterprise 预先配置了来自 ArcGIS Online 的底图集合。不支持在离线工作流中使用这些底图。例如，您无法在 Collector for ArcGIS 中离线使用预配置底图。
以下 python 脚本采用默认 ArcGIS Online 底图并将其作为地图项目添加到门户中。可离线使用底图地图项目并将其用于离线工作流中。为运行脚本，您需要提供 ArcGIS Online 帐户凭据。
运行此脚本时，您需要指定以下信息：
- 用于访问 Portal for ArcGIS 的 URL。该 URL 可以是 ArcGIS Web Adaptor URL （例如 https://webadaptorhost.domain.com/webadaptorname），也可以是托管门户的计算机 URL（例如 https://portal.domain.com:7443/arcgis）。指定 URL 时必须将计算机的完全限定域名包括在内。
- 门户中帐户的用户名和密码。
- 将创建新地图项目的文件夹的名称。如果未提供此文件夹，则会在您的根文件夹中创建地图项目。
- ArcGIS Online 帐户的用户名和密码。此脚本会将您的 ArcGIS Online 凭据嵌入到新地图项目中，这将启用底图的离线功能。
以下示例将在您的根文件夹中创建底图集合。这些底图中包括您的 ArcGIS Online 凭据，这样诸如 Collector for ArcGIS 等应用程序便可在离线工作流中使用这些底图。
