Google app engine JSON/AJAX not working - ajax

Question

Here is my JS code:
<script>
$("#comments").click(function(event) {
$.ajax({
type: "GET",
url: '/localhost:8080/comment',
data: JSON.stringify(
{
'name': 'anon',
'subject': 'MY COMMENTS',
}),
contentType: 'application/json',
success: function(data,textStatus, jqXHR) {
console.log('POST response: ');
console.log(data);
}
});
});
</script>
and here is my Python Code:
class Guestbook(webapp2.RequestHandler):
def get(self):
Jguest_data = json.loads(self.request.body)
return self.response.out.write(json.dumps(Jguest_data))
I got the error 404 Resource not found. After digging around there is some issues with localhost . so I tried with JSONP as follows:
<script>
$("#comments").click(function(event) {
$.ajax({ // ajax call starts
url: "localhost:8080/comment", //
type: "GET",
data: JSON.stringify(
{
'name': 'anon',
'subject': 'MY COMMENTS',
}),
dataType: "jsonp", // Choosing a JSON datatype
success: function(data,textStatus,jqXHR)
{
console.log('POST response: ');
console.log(data);
}
});
});
</script>
That still does not work... I get "No JSON object could be decoded" Error.
I tried replacing JSON.loads with JSON.load... and that still errors out...
Can someone please let me know what the issue is?
Thanks a mil in advance

Answer 1

when you do a GET request with ajax you are using url parameters.
so there is no body in the request.
make a POST and change your get() to post()

Answer 2

You should edit your app.yaml file if there is one in your project, and if there is not one, add one.
Add this code to your file (app.yaml).
-url: /comment
script: <url-to-the-server-side-script>
You can see a more complete app.yaml documentation for use with python here.
