Clip token protected WCS layer

GiacomoFavaron — Mon, 01 Jul 2024 14:22:27 GMT

I am trying to create a geoprocessing service that let you created a buffer and use that buffer to clip a WMS service I published on my Portal.

The WMS service is protected and I managed to get to the service using a token but I cannot find a way to download the data.

This is my code, what am I doing wrong?

import arcpy
from arcpy import env
import requests
import json
from json import loads, dumps

env.outputCoordinateSystem = arcpy.SpatialReference(4326)

#Buffer
Point = arcpy.GetParameterAsText(0)
Buffer ="in_memory/Buffer"
Dist = 100
Distance = str(Dist) + " Meters"

outBuffer = arcpy.Buffer_analysis(Point, Buffer, Distance)

arcpy.SetParameter(1, outBuffer)

for row in arcpy.da.SearchCursor(outBuffer, ["SHAPE@"]):
   extent = row[0].extent
   XMin = str(extent.XMin)
   YMin = str(extent.YMin)
   XMax = str(extent.XMax)
   YMax = str(extent.YMax)

coordinates = XMin + "," + YMin + "," + XMax + "," + YMax
arcpy.AddMessage(coordinates)

resp = requests.post("https://xyzxyzxy.com/arcgis/sharing/rest/generateToken?f=json",
data={"username":"xyzxy", "password":"xyzxy",
"referer":"https://xyzxyzxy.com"})

tokenCode = str(json.dumps(resp.json()["token"]))
arcpy.AddMessage(tokenCode)

mapService = "https://xyzxyzxy.com/arcgis/services/MapServices/NameofLayer/MapServer/WCSServer?SERVICE=WCS&VERSION=1.1.1&REQUEST=GetCoverage&COVERAGE=NameofLayer&CRS=EPSG:4326&BBOX=" + coordinates + "&FORMAT=GTiff" + "?f=json&token=" + tokenCode
arcpy.AddMessage(mapService)

arcpy.SetParameter(2, mapService)

I think I have problems building the request. After looking at the results I received back from the server I changed the request to:

https://xyzxyzxy.com/arcgis/services/MapServices/NameofLayer/MapServer/WCSServer?SERVICE=WCS&VERSION=1.0.0&REQUEST=GetCoverage&COVERAGE=NameofLayer&BOUNDINGBOX=-1.16,52.29,-1.15,52.30,urn:ogc:def:crs:EPSG::4326&FORMAT=geotiff?f=json&token=

However I get the error message that " parameter COVERAGE is invalid" even if passed the name of the layer.
