如何通过URLSession请求获取cookie？

import Foundation

let url = URL(string: "https://example.com")
var request = URLRequest(url: url!)
request.httpMethod = "GET"

let session = URLSession.shared
let task = session.dataTask(with: request) { (data, response, error) in
    if let httpResponse = response as? HTTPURLResponse {
        if let cookies = HTTPCookieStorage.shared.cookies(for: url!) {
            for cookie in cookies {
                print("Cookie: \(cookie.name) = \(cookie.value)")
            }
        }
    }
}

task.resume()
