Ejemplo: Inicie el servicio de geometría

En este ejemplo se obtiene un token administrativo y luego se inicia el servicio de geometría. Se trata de una secuencia de comandos de prueba, ya que todos los sitios de ArcGIS 10.1 for Server incluyen un servicio de geometría llamado Geometría que se detiene por defecto. Además, esta solicitud solo necesita dos parámetros: el token y la respuesta formato.

Iniciar un servicio requiere privilegios administrativos, de modo que debe proporcionarse un nombre de usuario y la contraseña con privilegios de administrador al ejecutar esta secuencia de comandos.
