Python post request to Map Service with spatial filter

Question

Hi, i have used this script to call a Map Service an retrivethe geometry: URL = "http://server/arcgis/rest/services/services/MapServer/0/query" where = "1=1" fields = "*" query = "?where={}&outFields={}&returnGeometry=true&f=json".format(where, fields) fsURL = URL + query fs = arcpy.FeatureSet() fs.load(fsURL) ‍‍‍‍‍‍‍ Now i need to request this service with POST method by REST folder and pass it InpputGeometry with Spatial Relationship, so i can load only a subset of data. How i can do this? There is some example? Thanks

hi, James, thanks for your replay. Your response if that I needed and i have correct my script in this way : desc = arcpy.Describe(m) xmin = desc.extent.XMin xmax = desc.extent.XMax ymin = desc.extent.YMin ymax = desc.extent.YMax envelope = '{"xmin":%s,"ymin":%s,"xmax":%s,"ymax":%s}' % (xmin, xmax, ymin, ymax) line = arcpy.da.SearchCursor(m, ("SHAPE@JSON",)).next()[0] queryURL = "http://server/arcgis/rest/services/services/MapServer/1/query" params = urllib.urlencode({'f': 'json', 'geometryType': 'esriGeometryEnvelope', 'inSR':'4326', 'geometry':envelope, 'spatialRel': 'esriSpatialRelIntersects','relationParam': 'FFFTTT***', 'outFields': '*','outSR':'4326', 'returnGeometry': 'true'}) req = urllib2.Request(queryURL, params) response = urllib2.urlopen(req) jsonResult = json.load(response)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ but now i would like to create a in_memory feature of this result but fc = arcpy.CopyFeatures_management(jsonResult, r"in_memory\feature")‍ copy feature give me errorinstead with arcpy.Feature Set i could. I can create feature by the result of query Map Service? Thanks

Edit: Sorry, I misread/misunderstood what you were asking for. You will want to implement urlib2. approw[2] is the 'SHAPE@JSON' key of a SearchCursor of the feature class we are intersecting with the map service features. import urllib, urllib2 #process waterbody features #FDEP is the authoritative source and steward for this data and is accessed via thier published map service queryURL = "http://ca.dep.state.fl.us/arcgis/rest/services/OpenData/WBIDS/MapServer/0/query" params = urllib.urlencode({'f': 'json', 'geometryType': 'esriGeometryPolygon', 'geometry': approw[2], 'spatialRel': 'esriSpatialRelIntersects', 'where': '1=1', 'outFields': 'WBID,WATER_TYPE,WATERBODY_NAME,CLASS', 'returnGeometry': 'false'}) req = urllib2.Request(queryURL, params) response = urllib2.urlopen(req) print '*** req start ***' print str(approw[2]) print '*** req end ***' jsonResult = json.load(response) for feature in jsonResult['features']: wbdy = feature['attributes']['WATERBODY_NAME'] wbdytype = feature['attributes']['WATER_TYPE'] wbid = feature['attributes']['WBID'] wbdyclass = feature['attributes']['CLASS'] #print wbdy, wbdytype, wbid values = {'WATERBODYID': wbid, 'WATERBODYNAME': wbdy, 'WATERBODYTYPE': wbdytype, 'WATERBODYCLASS': wbdyclass } waterbodieslst.append(values) data.update({'WATERBODIES': waterbodieslst}) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
