AFNetworking 500 response body

Question

I\'ve been using AFNetworking 2.0 in my app. I\'ve noticed that if my web-service returns a 500 status code I do not get the body of the response.

Here is an example

UPDATE: I have created a github repository to contain the latest code I am using. All changes will be posted there. https://github.com/Hackmodford/HMFJSONResponseSerializerWithData

The answer comes from this issue on github. https://github.com/AFNetworking/AFNetworking/issues/1397

gfiumara is the dev who came up with this. I have only slightly modified his subclass of AFJSONResponseSerializer to include an actual string instead of the NSData

//MSJSONResponseSerializerWithData.h

#import "AFURLResponseSerialization.h"

/// NSError userInfo key that will contain response data
static NSString * const JSONResponseSerializerWithDataKey = @"JSONResponseSerializerWithDataKey";

@interface MSJSONResponseSerializerWithData : AFJSONResponseSerializer

@end

//  MSJSONResponseSerializerWithData.m

#import "MSJSONResponseSerializerWithData.h"

@implementation MSJSONResponseSerializerWithData

- (id)responseObjectForResponse:(NSURLResponse *)response
                           data:(NSData *)data
                          error:(NSError *__autoreleasing *)error
{
    if (![self validateResponse:(NSHTTPURLResponse *)response data:data error:error]) {
        if (*error != nil) {
            NSMutableDictionary *userInfo = [(*error).userInfo mutableCopy];
            userInfo[JSONResponseSerializerWithDataKey] = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
            NSError *newError = [NSError errorWithDomain:(*error).domain code:(*error).code userInfo:userInfo];
            (*error) = newError;
        }

        return (nil);
    }

    return ([super responseObjectForResponse:response data:data error:error]);
}

@end

Here is an example of how I use it in the failure block.

} failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"%@",[error.userInfo objectForKey:@"JSONResponseSerializerWithDataKey"]); 
    }];
