示例:更新 web 地图服务的 URL

此示例更新 web 地图中引用服务的 URL。这尤其适用于服务的 URL 已经更改并且您不想要求用户移除或向所有 web 地图重新添加该服务的情况。有很多原因可造成服务 URL 发生更改。例如,服务可能迁移到了新的服务器,更改了服务名称,服务被移动到服务器的另一个文件夹中或服务器的域前缀已经更改。


  • 用于访问 Portal for ArcGIS 的 URL。该 URL 可以是 ArcGIS Web Adaptor URL,或托管门户的计算机 URL,例如,。指定 URL 时必须包含完全限定的机器域名。
  • 具有门户管理权限的帐户的用户名和密码。
  • 将更新的项目类型。指定“web 地图”以更新门户中的所有 Web 地图。
  • Web 地图中当前引用的服务 URL,例如,
  • Web 地图中将更新的服务的 URL,例如,

下面的示例将门户中所有 Web 地图的地图服务 URL 替换为地图服务 URL
