How to post data to Google App Engine for python with jQuery

jQuery side:

$.post(

"http://xxxxxxxxxxxxxxxxx.appspot.com/introdata",

{"viewerid": viewerid, "fromid": from, "toid": to, "introreason": reason},

function(data, status) {

$("#oktext").css('font-size', '12px').css("font-weight", "bold").css("color", "red").fadeIn(2000);

$("#oktext").fadeOut(5000);

}

);

GAE side:

from django.utils import simplejson

...

class AddHandler(webapp.RequestHandler):

       ...

def post(self):

viewerid = self.request.get('viewerid')

data = introData(viewerid=viewerid)

data.fromid = self.request.get('fromid')

data.toid = self.request.get('toid')

data.introreason = self.request.get('introreason')

data.unreadflag = '1'

data.put()

...

def main():

application = webapp.WSGIApplication(

[

('/introdata',AddHandler),

...

],

debug=True)

wsgiref.handlers.CGIHandler().run(application)

if __name__ == '__main__':

main()
