我无法在func中正确检查来自URLSession的响应状态。斯威夫特

let session = URLSession(configuration: .default, delegate: self, delegateQueue: nil)

extension YourClass: URLSessionDelegate {
    func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive response: URLResponse, completionHandler: @escaping (URLSession.ResponseDisposition) -> Void) {
        // 在这里检查响应状态
        if let httpResponse = response as? HTTPURLResponse {
            let statusCode = httpResponse.statusCode
            // 根据状态码进行相应处理
            if statusCode == 200 {
                completionHandler(.allow)
            } else {
                completionHandler(.cancel)
            }
        }
    }
    
    func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) {
        // 在这里处理错误
        if let error = error {
            print("请求出错：\(error.localizedDescription)")
        }
    }
}

func makeRequest() {
    guard let url = URL(string: "https://example.com") else { return }
    let task = session.dataTask(with: url)
    task.resume()
}
