I\'m having a similar issue to the one discussed here.
I\'m attempting to post JSON to a server.
Here\'s the Objective-C code that should work, but
I'm using POST, so query strings are not involved. But maybe the limitation exists with POST data as well?
The limitation is not on POST, it's URL form encoding. I go on to say that you should encode as JSON, which you can do with the following configuration change to your manager:
manager.requestSerializer = [AFJSONRequestSerializer serializer];.
Also, unless you're actually constructing a multi-part request, don't use the constructingBodyWithBlock version of that method.
