Accessing ArcGIS Online REST Services through a proxy with Python
Hello All,
I'm trying to run a script to access an ArcGIS Online REST web service and am behind an orginizational firewall, so I need to go over an authenticated proxy. My understanding is that urllib2 is supposed to pull the proxy settings from my system automatically so I shouldn't need to add any code dealing with that, but I keep getting a socket timeout error (60010) right after the script attempts to establish a connection -- I think this has to do with the proxy, but maybe I'm wrong. Has anyone else run into this problem and found a sollution? I tried importing the'socket' module and setting the timout value to 'NONE', as well as setting the expiration to a larger value, but the error keeps appearing after 1 minute. I've attached the part of my code dealing with the connection to the service -- does anyone out there have any ideas? Any feedback would be highly appreciated!
import json, urllib, urllib2 import sys, os import arcpy import shutil class GetToken(object): # find feature service attachments, send to directory def urlopen(self, url, data=None): # open url, send response referer = "http://www.arcgis.com/arcgis/rest" req = urllib2.Request(url) req.add_header('Referer', referer) if data: response = urllib2.urlopen(req, data) else: response = urllib2.urlopen(req) return response def gentoken(self, username, password, referer = 'www.arcgis.com', expiration=60): # gets token from referrer query_dict = {'username': username, 'password': password, 'expiration': str(expiration), 'client': 'referer', 'referer': referer, 'f': 'json'} query_string = urllib.urlencode(query_dict) token_url = "https://www.arcgis.com/sharing/rest/generateToken" token_response = urllib.urlopen(token_url, query_string) token = json.loads(token_response.read()) if "token" not in token: print token['messages'] exit() else: return token['token']
