Now you have a simple REST interface.
$ curl http://localhost:8888/_ah/api/superheroes/v1/superheroes { "items": [ { "knownAs" : "Champion of the Obvious", "realName" : "Brad Abrams" }, { "knownAs" : "Mr. Justice", "realName" : "Chris Ramsdale" }
Real result = superheroes.list().execute();
GTLQuerySuperHeroesV1 *query = [GTLQuerySuperHeroesV1 queryForSuperHeroesList]; [service executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLSuperHeroes *object, NSError *error) { NSArray *items = [object items]; }];
// ... var ROOT = 'https://' + window.location.host + '/_ah/api'; gapi.client.load('superheroes', 'v1', loadSuperheroesCallback, ROOT); // Get the list of superheroes gapi.client.superheroes.superheroes.list().execute(function(resp) { displaySuperheroesList(resp); });
