change how AFJSONRequestSerializer encodes JSON

Question

I am using AFNetworking. The AFHTTPRequestOperationManager requestSerializer is set to use AFJSONRequestSerializer.

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager] manager.requestSerializer = [AFJSONRequestSerializer serializer];

HTTP Body with current setup: {"key" : "http:\/\/myURL.com\/}

Desired HTTP Body: {"key" : "http://myURL.com/}

How can I prevent / from being escaped with \?

In order to resolve this issue I subclassed AFJSONRequestSerializer and overrode requestBySerializingRequest:withParameters:error:

- (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request withParameters:(nullable id)parameters error:(NSError *__autoreleasing  _Nullable * _Nullable)error {
    NSURLRequest *myRequest = [super requestBySerializingRequest:request withParameters:parameters error:error];

    NSData *jsonData = myRequest.HTTPBody;

    if (jsonData) {
        NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

        if (jsonString) {
            NSString *sanitizedString = [jsonString stringByReplacingOccurrencesOfString:@"\\/" withString:@"/" options: NSCaseInsensitiveSearch range: NSMakeRange(0, [jsonString length])];
            NSMutableURLRequest *mutableRequest = [myRequest mutableCopy];
            mutableRequest.HTTPBody = [sanitizedString dataUsingEncoding:NSUTF8StringEncoding];
            myRequest = mutableRequest;
        }
    }

    return myRequest;
}
