使用python从地图服务中提取数据

arcgis server 发布的wmts服务，可以下载为lyr 文件，想转为shapefile。

数据不在文件内的，复制要素，另存都无效

import urllib.parse, urllib.request, os, arcpy

url = "http://ydt.haxxxxumap.g080/arcgis/rest/services/ghg_2021/MapServer/8/query?"

params = {'where': 'objectid<=2000 and objectid>1000',
'geometryType': 'esriGeometryEnvelope',
'spatialRel': 'esriSpatialRelIntersects',
'relationParam': '',
'outFields': '*',
'returnGeometry': 'true',
'geometryPrecision':'',
'outSR': '',
'returnIdsOnly': 'false',
'returnCountOnly': 'false',
'orderByFields': '',
'groupByFieldsForStatistics': '',
'returnZ': 'false',
'returnM': 'false',
'returnDistinctValues': 'false',
'f': 'pjson'
}

encode_params = urllib.parse.urlencode(params).encode("utf-8")

response = urllib.request.urlopen(url, encode_params)
json = response.read()

with open("mapservice.json", "wb") as ms_json:
    ms_json.write(json)

ws = os.getcwd() + os.sep
arcpy.JSONToFeatures_conversion("mapservice.json", ws + "mapservice.shp")
