Network Programming in .NET

Labnol’s AppEngine Proxy is useful for viewing other pages requested via Google AppEngine, however, it does change the HTML, and doesn’t handle POST data. This is a code example in Google AppEngine Python showing how to implement a HTTP proxy in a similar way to Labnol.

from google.appengine.ext import webapp
from google.appengine.ext.webapp import util

import urllib2
import urllib
import re
import array
import urllib2


class MainHandler(webapp.RequestHandler):
	def get(self):	
		#self.response.out.write('[GET] The URL Requested was ' + self.request.query_string)
		response = urllib2.open(self.request.query_string)
		html = response.read()
		self.response.out.write(html)

	def post(self):	
		#self.response.out.write('[POST] The URL Requested was ' + self.request.query_string + "
")		
		args = self.request.arguments()
		strPostdata = ""
		for arg in args:
			strPostdata = strPostdata + arg + "=" + self.request.get(arg) + "&"		
		#self.response.out.write("[POST] The data was:" + strPostdata)
		request = urllib2.Request(self.request.query_string)
		request.add_data(str(strPostdata))
		response = urllib2.urlopen(request)
		html = response.read()
		self.response.out.write(unicode(html,"latin1"))

def main():
    application = webapp.WSGIApplication([('/', MainHandler)],
                                         debug=True)
    util.run_wsgi_app(application)


if __name__ == '__main__':
    main()
