Hello list
I am trying to do similar to http://www.openlayers.org/dev/examples/getfeatureinfo-popup.html example, but I could not done yet because feature did not view probably. I am using Openlayer and Geoext running in mapfish enviroment (but without any mapfish commends and library only run as env of mapfish). I put my example on http://131.175.143.99/form.html and when I click on the map, responses an errors as !/usr/bin/env python """This is a blind proxy that we use to get around browser restrictions that prevent the Javascript from loading pages not on the same server as the Javascript. This has several problems: it's less efficient, it might break some sites, and it's a security risk because people can use this proxy to browse the web and possibly do bad stuff with it. It only loads pages via http and https, but it can load any content type. It supports GET and POST requests.""" import urllib2 import cgi import sys, os # Designed to prevent Open Proxy type stuff. allowedHosts = ['131.175.143.99', 'localhost:8081'] method = os.environ["REQUEST_METHOD"] if method == "POST": qs = os.environ["QUERY_STRING"] d = cgi.parse_qs(qs) if d.has_key("url"): url = d["url"][0] else: url = "http://131.175.143.99"; else: fs = cgi.FieldStorage() url = fs.getvalue('url', "http://131.175.143.99";) try: host = url.split("/")[2] if allowedHosts and not host in allowedHosts: print "Status: 502 Bad Gateway" print "Content-Type: text/plain" print print "This proxy does not allow you to access that location (%s)." % (host,) print print os.environ elif url.startswith("http://";) or url.startswith("https://";): if method == "POST": length = int(os.environ["CONTENT_LENGTH"]) headers = {"Content-Type": os.environ["CONTENT_TYPE"]} body = sys.stdin.read(length) r = urllib2.Request(url, body, headers) y = urllib2.urlopen(r) else: y = urllib2.urlopen(url) # print content type header i = y.info() if i.has_key("Content-Type"): print "Content-Type: %s" % (i["Content-Type"]) else: print "Content-Type: text/plain" print print y.read() y.close() else: print "Content-Type: text/plain" print print "Illegal request." except Exception, E: print "Status: 500 Unexpected Error" print "Content-Type: text/plain" print print "Some unexpected error occurred.
