示例：复制内容
本示例将一个门户 (A) 成员拥有的全部内容复制到另一门户 (B)。内容的所有权从门户 A 转移到门户 B 的指定帐户。这对于有两个门户的组织很有用。例如，一个门户供内部使用，另一个门户供外部使用；对于实施开发和生产环境的组织，上述情况也同样有用。本脚本还可用于将内容从 Portal for ArcGIS 移至 ArcGIS Online，反之亦然。
运行此脚本时，您需要指定以下信息：
- 用于访问第一个门户 (A) 的 URL。该 URL 可以是 ArcGIS Web Adaptor URL，例如，https://webadaptorA.domain.com/arcgis 或托管门户的计算机 URL，例如，https://portalA.domain.com:7443/arcgis。指定 URL 时必须将计算机的完全限定域名称包括在内。
- 对门户 A 具有管理权限的帐户的用户名和密码。
- 将从门户 A 复制到门户 B 的内容的所有者帐户的用户名和密码，例如 sarah。
- 用于访问第二个门户 (B) 的 URL。该 URL 可以是 ArcGIS Web Adaptor URL，例如，https://webadaptorB.domain.com/arcgis 或托管门户的计算机 URL，例如，https://portalB.domain.com:7443/arcgis。指定 URL 时必须将计算机的完全限定域名称包括在内。
- 对门户 B 具有管理权限的帐户用户名和密码。
- 将拥有从门户 (A) 复制到门户 (B) 的内容的帐户的用户名和密码，例如，robert。
- 内容将被复制的门户 B 上的成员文件夹。该位置始终为根文件夹 (/)。无法将内容复制到根文件夹下的子文件夹中。
下面的示例会将门户 A 的成员 sarah 所拥有的全部内容复制给门户 B 的成员 robert：
python copyContent.py https://webadaptorA.domain.com/arcgis admin pass.word owner:sarah https://webadaptorB.domain.com/arcgis admin password robert /
#!/usr/bin/env python
# Requires Python 2.7+
# Sample Usage:
# python copyContent.py <sourcePortal> <sourceAdmin> <sourcePassword>
# <query> <destinationPortal> <destAdmin>
# <destPassword> <destOwner> <destFolder>
