NSDictionary *parameters = [NSDictionary dictionaryWithObject:json forKey:@"json"];

[httpClient postPath:@"/xxx/yyyy/zzzz" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"success parsing %@",responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"failure parsing  %@",error);
    }];
