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 ArcGIS Enterprise 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),也可以是托管门户的计算机 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包括在内。
  • 具有门户 A 管理权限的帐户的用户名和密码。
  • 拥有将从门户 A 复制到门户 B 的内容的帐户的用户名,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),也可以是托管门户的计算机 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包括在内。
  • 具有门户 B 管理权限的帐户的用户名和密码。
  • 将拥有从门户 (A) 复制到门户 (B) 的内容的帐户的用户名,例如 robert
  • 将从中复制内容的门户 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
