Question

I’m having the strangest issue right now with google app engine. I’m sending a POST request from iOS and google app engine instead invokes the GET handler.

I’ve sandboxed this one situation for testing and can’t get it figured out. I have an iOS app that just sends a request. And I’ve commented out everything on GAE except for the service. The service only logs a parameter and returns.

The iOS app I’ve tried using two different ways of sending the request. Neither works.

iOS Code:

/*
NSURL * url = [NSURL URLWithString:@"http://beermonster-gngrwzrd.appspot.com/TestParameter"];
ASIFormDataRequest * _fdrequest = [[ASIFormDataRequest alloc] initWithURL:url];
[_fdrequest setPostValue:@"hello" forKey:@"testkey"];
[_fdrequest startAsynchronous];
*/

NSURL * __url = [NSURL URLWithString:@"http://beermonster-gngrwzrd.appspot.com/TestParameter"];
NSMutableURLRequest * __request = [NSMutableURLRequest requestWithURL:__url];
[__request setHTTPMethod:@"POST"];
NSString * post = [NSString stringWithFormat:@"testkey=hello"];
[__request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection sendSynchronousRequest:__request returningResponse:nil error:nil];

My App engine handler:

class TestParameter(webapp.RequestHandler):
def post(self):
    logging.debug(self.request.get("testkey"))
    self.response.out.write(self.request.get("testkey"))
    print self.request.get("testkey")
def get(self):
    logging.debug("get")
    logging.debug(self.request.get("testkey"))
    self.response.out.write(self.request.get("testkey"))

The output in the GAE logs shows the “get” code path which isn’t correct.

Any ideas why POST requests would come into GAE as a GET? Is there some configuration in GAE that I missed?

Thanks!

From what I can tell if you want to send POST requests to GAE. Make sure you do it on https. If you make the request on a non-https attempt, it sends back a 302 redirect to the https version of the request. But if whatever you’re using to send the request doesn’t correctly handle 302’s it might resend the request incorrectly.
