AFNetworking 2.0 Get JSON from code 400 in failure block

Question

I\'m using AFHTTPRequestOperationManager for a POST request. Now I\'m deliberately entering incorrect information to handle a 400 erro

Answer 1

You can do either of these solutions

1) Set the acceptableStatusCodes to accept your 400 statusCode, and you handle in the success block

manager.responseSerializer.acceptableStatusCodes = [NSIndexSet indexSetWithIndex:400];

2) Create a custom ResponseSerializer, like this JSONResponseSerializerWithData, to insert the responseObject into the NSError userInfo, and handle in the failure block

Pro tip: AFNetworking is opensource, just take a look at AFHTTPRequestOperation for methods

setCompletionBlockWithSuccess:failure:

responseObject

error
