Python常见问题
我有36个服务运行在ArcGIS服务器上，并希望导出csv文件中每个服务的所有属性。我设法在ESRI帮助台http://resources.arcgis.com/en/help/main/10.2/index.html#//0154000005wt000000的帮助下编写了一个代码，在请求中添加了属性“maxImageHeight”和“maxImageWidth”。但是，如果我运行代码，它开始工作，写入前22个服务的属性，但是之后它突然停止并返回
回溯（最近一次呼叫）： 文件“D:\SCRIPTS\Py SCRIPTS\ArcPy\AGS-ArcPy\AGS_service_report_as_csv2.Py”，第436行，in 系统出口（主(系统argv[1:]）） 文件“D:\SCRIPTS\Py SCRIPTS\ArcPy\AGS-ArcPy\AGS_service_report_as_csv2.Py”，第201行，在main中 +“不适用”+“\n” KeyError:'最大高度'
这很奇怪，因为它为第一批服务提供了“maxImageHeight”属性。在
