检查Swift中的互联网访问(而不仅仅是网络连接)

import Foundation

func checkInternetAccess() {
    guard let url = URL(string: "https://www.example.com") else {
        print("Invalid URL")
        return
    }
    
    let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
        if let error = error {
            print("Internet access failed: \(error.localizedDescription)")
        } else if let httpResponse = response as? HTTPURLResponse {
            if httpResponse.statusCode == 200 {
                print("Internet access is available")
            } else {
                print("Internet access failed with status code: \(httpResponse.statusCode)")
            }
        }
    }
    
    task.resume()
}
