示例：创建站点

本示例介绍了如何根据用户提供的值（主站点管理员帐户、配置存储位置和服务器目录的根位置）创建 ArcGIS Server 站点。这些值与在 ArcGIS Server 管理器中手动创建站点时要求用户输入的值完全相同。

通过简单传入所需的主站点管理员的用户名和密码以及服务器名称和端口号，仅使用较少代码即可调用 ArcGIS REST API 中的 createNewSite 操作。在下例中，可灵活地定义所需配置存储位置和根服务器目录位置。大多数代码与创建目录相关联。

通过编程方式定义服务器目录时，必须将用于详细描述目录属性的大量 JavaScript 对象表示法 (JSON) 传入 createNewSite 操作。在下例中，将使用 Python 字典配置目录属性。然后，通过使用 Python 的 json.dumps() 函数将这些字典序列化到 JSON 中。这有助于保持示例的可读性。

下面所使用的目录属性与创建站点时 ArcGIS Server 管理器应用的默认属性完全相同。您可根据喜好修改这些属性。
