Ios MKNetworkKit如何使用会话cookie获取服务器响应头

我正在使用MKNetworkKit库

我的服务器似乎允许我使用HTTP Post进行身份验证，我从服务器上获取了一些JSON数据：

{auth: true}

但是，我想存储服务器生成的会话cookie，但我不知道如何使用 MKNetworkKit获取会话cookie

有人知道吗

最后，在仔细研究之后，得到如下响应标题：

-(void)login
{
    NSMutableDictionary *params = [[NSMutableDictionary alloc] init];

    [params setObject:@"testusername" forKey:@"username"];
    [params setObject:@"abcdef123" forKey:@"password"];

    MKNetworkOperation *op = [self.mkEngine operationWithPath:@"/auth/local.json" params:params httpMethod:@"POST"];

    [op addCompletionHandler:^(MKNetworkOperation *completedOperation)
    {
        NSLog(@"response headers: %@", completedOperation.readonlyResponse.allHeaderFields);
    } errorHandler:^(MKNetworkOperation *completedOperation, NSError *error) {
        NSLog(@"Server error: %@", [error localizedDescription]);
    }];

    [self.mkEngine enqueueOperation:op];
}

-_-!
