from google.appengine.ext import webapp
from google.appengine.ext.webapp import util
from xml.dom import minidom
from google.appengine.ext.webapp.util import run_wsgi_app
import httplib, json
import cgi
class MainPage(webapp.RequestHandler):
def get(self):
self.response.out.write("""
<html>
<head>
<title>Simple Url Shortener</title>
<body>
Url shortener using Google URL Shortener API. Masukkan url

</body>
</html>""")
class Cari(webapp.RequestHandler):
def post(self):
url = self.request.get('url')
conn = httplib.HTTPSConnection('www.googleapis.com')
conn.connect();
short = '"'+url+'"'
body = '{"longUrl": %s}' % short
headers = {'content-type':'application/json'}
conn.request('POST', '/urlshortener/v1/url', body, headers)
response = json.loads(conn.getresponse().read())
self.response.out.write('<html><title>Simple Url
Shortener</title><body>Url yang sudah dipendekin dari ', url, '
:<pre>')
self.response.out.write(response["id"])
self.response.out.write('</pre></body></html>')
application = webapp.WSGIApplication([('/', MainPage), ('/hasil',
Cari)], debug=True)
def main():
run_wsgi_app(application)
if __name__ == '__main__':
main()
and its get error message :

TypeError: escape_encode() argument 1 must be str, not unicode
anybody knows what should i do to troubleshoot this?
i use httplib module to make a connection and request.
