是否有可能在获取报头后，在开始获取数据之前中断NSURLSessionDownloadTask？

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let url = URL(string: "https://example.com/largefile.zip")!
        let request = URLRequest(url: url)
        
        let session = URLSession(configuration: .default, delegate: self, delegateQueue: OperationQueue.main)
        let dataTask = session.dataTask(with: request)
        
        dataTask.resume()
    }
}

extension ViewController: URLSessionDelegate {
    func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive response: URLResponse, completionHandler: @escaping (URLSession.ResponseDisposition) -> Void) {
        // 获取报头信息
        print("Headers: \(response.allHeaderFields)")
        
        // 取消任务
        dataTask.cancel()
        
        completionHandler(.cancel)
    }
}
