Swift: WKWebView需要身份验证。

class ViewController: UIViewController, WKNavigationDelegate {
    var webView: WKWebView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let webViewConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: view.bounds, configuration: webViewConfiguration)
        webView.navigationDelegate = self
        view.addSubview(webView)
        
        let url = URL(string: "https://example.com")
        let request = URLRequest(url: url!)
        webView.load(request)
    }
    
    // WKNavigationDelegate methods
    func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
        // 在这里进行身份验证逻辑的处理
        // ...
        
        // 完成身份验证
        completionHandler(.useCredential, credential)
    }
}
