AFNetworking 2 - get error json body [duplicate]

Question

This question already has answers here:

AFNetworking 2.0 Get JSON from code 400 in failure block (4 answers)

Closed 8 years ago.

I'm using latest AFNetworking for my app which speaks with REST API server.

When I get some 500 error from it with JSON body something like

{ "message": "my error message" },

I cannot retrieve this message from NSError which lib responds to me:

[api setupUser:data success:^(AFHTTPRequestOperation *operation, id responseObject) {
   // some success handle
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
   // cannot get json response of error :(
}];

How do you workaround it?

Answer 1

The answer was simple - operation.responseObject in failure callback contains json data as well. Sweet ^.^
