android post json, app engine gives 404

Im trying to learn more about webbbservices and python at the same time. So if you got ideas or solution, explain to me like Im 5. :)

So I want to send a string to the server and just store it in a database (guestbook). I've managed to do this with a webpage but now I want to access and store a string by phone, this is the python code:

import os
import urllib
import json

from google.appengine.ext import ndb

import jinja2
import webapp2


JINJA_ENVIRONMENT = jinja2.Environment(
    loader=jinja2.FileSystemLoader(os.path.dirname(__file__)),
    extensions=['jinja2.ext.autoescape'],
    autoescape=True)

DEFAULT_GUESTBOOK_NAME = 'default_guestbook'
GUESTBOOKS_NAME = 'guestbook'

def guestbook_key(guestbook_name=DEFAULT_GUESTBOOK_NAME):
    return ndb.Key('Guestbook', guestbook_name)


class Guestbook(ndb.Model):
    identity = ndb.StringProperty(indexed=True


class Chat(webapp2.RequestHandler):
    def get(self):

        guestbook = Guestbook(parent=guestbook_key(GUESTBOOKS_NAME))
        guestbook.identity=self.request.get("content") 
        guestbook.put()
        self.response.headers['Content-Type'] = "text/plain"
        self.response.out.write("ok")

application = webapp2.WSGIApplication([
    (r'/chat', Chat),
], debug=True)

and this is the android code:

private void sendData(){

        try {
            JSONObject jsonobj = new JSONObject();
            jsonobj.put("content", "asdf1234");

            DefaultHttpClient httpclient = new DefaultHttpClient();
            HttpPost httppostreq = new HttpPost("http://<myappid>.appspot.com/chat/");

            StringEntity se = new StringEntity(jsonobj.toString());

            se.setContentType("application/json;charset=UTF-8");
            se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));

            httppostreq.setEntity(se);

            HttpResponse httpresponse = httpclient.execute(httppostreq);

            Log.d("Debug", "Response: " + EntityUtils.toString(httpresponse.getEntity()));

        } catch (JSONException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (Exception e){
            Log.d("Debug", "Exception: " + e.getMessage());
        }


    }

In your routing table : (r'/chat/(\d+)', Chat), this line maps the url to the handler.

which is handled by mapping the (\d+) to product_id in the get function of the handler.

valid urls

  • /chat/1
  • /chat/302490205

invalid urls

  • /chat
  • /chat/jedi

edit

since your posting your need a post method in your handler

def post(self):
    #do stuff
