Hello everyone,
I am able to call a  HTTP web service from Python using urllib, urllib2.
But now I need to add authentication adding the UserID and Password in order to call the another service.
This is the existing code:
import arcpy, urllib, urllib2,
url = r'https://wwww.example.com/GISAddress/Check.asmx/VerifyAddress'
 values = {'myAddress' : '100 SW 10 street'}
data = urllib.urlencode(values)
 req = urllib2.Request(url, data)
 response = urllib2.urlopen(req)
 the_page = response.read()
 t = ET.fromstring(the_page)
Thank you
