 Сбой приложения только на iOS после успешного обратного вызова WebAuthenticator через Universal App Link

Сообщение Anonymous »

Я переношу поток авторизации iOS .NET MAUI с того, который обрабатывает перенаправление с использованием устаревшей пользовательской схемы URL-адресов, на тот, который использует универсальную ссылку на приложение, проверенную с помощью файла apple-app-site-association, размещенного в Firebase.
Обратный вызов работает. Код получен успешно. Проблема в том, что приложение аварийно завершает работу после возврата из потока авторизации WebAuthenticator. Это проблема только iOS, а не Android, который отлично работает при использовании ссылки на приложение Android, обслуживаемой файлом assetslinks.json на том же сервере.
Короткий вопрос
У вас получилось? В этом случае пропустите все трудоемкие детали и объясните мне все! В противном случае вот...

Что я пробовал

  • Проверить ссылку на универсальное приложение с помощью настроек разработчика на iPhone.

  • При подключенном отладчике приложения введите URL-адрес в Safari со специальной страницы «теста перенаправления» на нашем сервере. Убедитесь, что достигнута точка останова в ContinueUserActivity. Убедитесь, что приложение не аварийно завершает работу при использовании универсальной ссылки на приложение таким образом.
< ol start="3">
[*]Установка точки останова для проверки возвращенного кода авторизации. Затем немедленно вернитесь, чтобы избежать каких-либо других исключений.

buttonLogin.Clicked += async (sender, e) =>
{
var clientId = "123456789012-1ok9rauo969og7aljrnri1gesrr7l1b3.apps.googleusercontent.com";
var redirectUrl = "https://myfirebasedomain.com/auth";
var scopes = "profile%20openid%20email";
var authUrl = $"https://accounts.google.com/o/oauth2/au ... pe=offline";

Uri authUri = new Uri(authUrl);
Uri callbackUri = new Uri(redirectUrl);

WebAuthenticatorResult result;
try
{
result = await WebAuthenticator.AuthenticateAsync(new WebAuthenticatorOptions
{
Url = authUri,
CallbackUrl = callbackUri,
PrefersEphemeralWebBrowserSession = true
});
}
catch (TaskCanceledException)
{
// 'Not' an error. The user simply cancelled this op.
return;
}
catch (Exception ex)
{
Debug.Fail(ex.Message);
return;
}

// Exchange the authorization code for an access token

var payload = new
{
code = result.Properties["code"],
redirectUri = redirectUrl,
clientId = clientId,
key = "web",
};
var jsonPayload = JsonConvert.SerializeObject(payload, Formatting.Indented);
var content = new StringContent(jsonPayload, Encoding.UTF8, "application/json");
using var httpClient = new HttpClient();
HttpResponseMessage? response = null;
string? error = null;

try
{
// Exchange token using secret stored on server.

// We are unable to attempt this. The async post causes this
// method to return, and when it does, the app crashes.
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
if (response != null)
{
error = await response.Content.ReadAsStringAsync();
}
Debug.Fail(error ?? "null");
}
};

Значение jsonPayload указывает на успех
{
"code": "4/0AanRRrte8fELNx0CyzgsPzrGCo46TLvkp_JhQaG0ao8DMmVLySwN4_8KIfAXNiouGAqkrQ",
"redirectUri": "https://myfirebasedomain.com/auth",
"clientId": "123456789012-1ok9rauo969og7aljrnri1gesrr7l1b3.apps.googleusercontent.com",
"key": "web"
}

  • Поднимаемся на уровень выше, чтобы обернуть ContinueUserActivity для исключений. Я могу установить точку останова для возвращаемого результата. Сбой происходит, если этому методу разрешен запуск с этого момента.
[Register("AppDelegate")]
public class AppDelegate : MauiUIApplicationDelegate
{
protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();
public override bool ContinueUserActivity(UIApplication application, NSUserActivity userActivity, UIApplicationRestorationHandler completionHandler)
{
bool result = false;
try
{
// Calling the BC is what causes the AuthenticateAsync task to complete.
result = base.ContinueUserActivity(application, userActivity, completionHandler);
}
catch (Exception)
{
// NO exception being caught here.
}
return result;
}
}


Мой вопрос:
AFAIK Я все делаю правильно, но может ли кто-нибудь указать причину сбоя? ? Я склонен зарегистрировать это как ошибку в WebAuthenticator для iOS, но прежде чем я сделаю что-нибудь глупое, пожалуйста, «проверьте мою работу!»
