带iOS Passkey的电容如何获取注册数据

Question

我正在为我的 Ionic 应用程序实现 Passkey，但我找不到任何插件，所以我正在构建自己的插件。一切正常，直到触发本机 iOS 上的密钥，但我无法从 iOS 获取注册数据。如何从 AppDelegate 获取数据？我的代码基于Apple官方文档示例：https://developer.apple.com/documentation/authenticationservices/connecting_to_a_service_with_passkeys。

在示例中，它需要 AppDelegate 来获取注册数据委托，但是我无法使我的 Capacitor 插件使用主 AppDelegate。因此，授权控制器在密钥注册后不会运行。从 webview 获取挑战并将其传递到本机并触发 iOS 设备上的密钥提示一切都已经正常，只是无法获取注册结果数据。

PasskeyPlugin.swift

@objc(PasskeyPlugin)
public class PasskeyPlugin: CAPPlugin {

    private let implementation = Passkey()
    
    @objc func create(_ call: CAPPluginCall) {
        let challenge: Data? = call.getString("challenge")!.data(using: .utf8)
        
        DispatchQueue.main.async {
            let signInViewController = SignInViewController(challenge: challenge!)
            self.bridge?.viewController?.present(signInViewController, animated: true, completion: nil)
        }
            
        call.resolve([
            "platform": "iOS Native Passkey",
        ])
    }
}

SignInViewController.swift

class SignInViewController: UIViewController {
    var challenge: Data!

    init(challenge: Data) {
        self.challenge = challenge
        print(self.challenge! as NSData)
        super.init(nibName: nil, bundle: nil)
    }

override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)

        signInObserver = NotificationCenter.default.addObserver(forName: .UserSignedIn, object: nil, queue: nil) {_ in
            self.didFinishSignIn()
        }

        signInErrorObserver = NotificationCenter.default.addObserver(forName: .ModalSignInSheetCanceled, object: nil, queue: nil) { _ in
            self.showSignInForm()
        }

        guard let window = self.view.window else { fatalError("The view was not in the app's view hierarchy!") }
        
        let userName = "Name"
        
        let accountManager = AccountManager()
        accountManager.signUpWith(userName: userName, challenge: self.challenge, anchor: window)
        
        // I cannot use the AppDelegate with errors
        // (UIApplication.shared.delegate as? AppDelegate)?.accountManager.signUpWith(userName: userName, challenge: self.challenge, anchor: window)
    }
}

AccountManager.swift

extension NSNotification.Name {
    static let UserSignedIn = Notification.Name("UserSignedInNotification")
    static let ModalSignInSheetCanceled = Notification.Name("ModalSignInSheetCanceledNotification")
}


class AccountManager: NSObject, ASAuthorizationControllerPresentationContextProviding, ASAuthorizationControllerDelegate {
    let domain = "com.domain.my"
    var authenticationAnchor: ASPresentationAnchor?
    var isPerformingModalReqest = false

    func signUpWith(userName: String, challenge: Data, anchor: ASPresentationAnchor) {
        self.authenticationAnchor = anchor
        
        if #available(iOS 15.0, *) {
            let publicKeyCredentialProvider = ASAuthorizationPlatformPublicKeyCredentialProvider(relyingPartyIdentifier: domain)
            
            // The userID is the identifier for the user's account.
            // Hard coded for example purposes
            let userID = "d0a4bc91-2def-4567-8983-9188a4ca2048".data(using: .utf8)!

            let registrationRequest = publicKeyCredentialProvider.createCredentialRegistrationRequest(challenge: challenge,
                                                                                                      name: "Some name", userID: userID)

            let authController = ASAuthorizationController(authorizationRequests: [ registrationRequest ] )

如何让authorizationController在本机设备上出现密码提示后运行？预先感谢您。

您能告诉我如何从自动填充凭据扩展中获取密码吗 如果我在 webauthn.io 上，那么我的应用程序会显示创建密钥弹出窗口，但然后什么也不起作用

请帮助我
