 App-Absturz nur auf iOS nach erfolgreichem WebAuthenticator-Rückruf über Universal App Link

Post by Guest »

Ich migriere einen .NET MAUI iOS-Autorisierungsfluss von einem, der die Weiterleitung mithilfe des inzwischen veralteten benutzerdefinierten URL-Schemas verarbeitet, zu einem, der einen universellen App-Link verwendet, der über eine auf Firebase gehostete Apple-App-Site-Association-Datei überprüft wird.
Der Rückruf funktioniert. Der Code wurde erfolgreich empfangen. Das Problem besteht darin, dass die App abstürzt, wenn sie vom WebAuthenticator-Autorisierungsfluss zurückkehrt. Dies ist nur ein Problem mit iOS, nicht mit Android, das perfekt funktioniert, wenn ein Android-App-Link verwendet wird, der von einer assetlinks.json-Datei auf demselben Server bereitgestellt wird.
Kurze Frage
Haben Sie das hinbekommen? In diesem Fall überspringen Sie alle mühsamen Details und führen Sie mich durch! Ansonsten ist hier...

Was ich versucht habe

  • Überprüfen den Universal App Link mithilfe der Entwicklereinstellungen auf dem iPhone.

  • Fügen Sie mit angeschlossenem App-Debugger die URL in Safari von einer speziellen „Redirect-Test“-Seite auf unserem Server ein. Stellen Sie sicher, dass ein Haltepunkt in ContinueUserActivity erreicht wird. Stellen Sie sicher, dass die App nicht abstürzt, wenn der Universal App Link auf diese Weise ausgeübt wird.
< ol start="3">
[*]Festlegen eines Haltepunkts zur Überprüfung des zurückgegebenen Autorisierungscodes. Dann kehren Sie sofort zurück, um die Möglichkeit weiterer Ausnahmen zu vermeiden.

Code: Select all

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/auth?client_id={clientId}&redirect_uri={redirectUrl}&prompt=consent&response_type=code&scope={scopes}&access_type=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");
}
};
Der Wert von jsonPayload zeigt den Erfolg an

Code: Select all

{
"code": "4/0AanRRrte8fELNx0CyzgsPzrGCo46TLvkp_JhQaG0ao8DMmVLySwN4_8KIfAXNiouGAqkrQ",
"redirectUri": "https://myfirebasedomain.com/auth",
"clientId": "123456789012-1ok9rauo969og7aljrnri1gesrr7l1b3.apps.googleusercontent.com",
"key": "web"
}
  • Eine Ebene nach oben gehen, um die ContinueUserActivity für Ausnahmen einzuschließen. Ich kann einen Haltepunkt für das Rückgabeergebnis festlegen. Der Absturz tritt auf, wenn diese Methode ab diesem Punkt ausgeführt werden darf.

Code: Select all

[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;
}
}
Meine Frage:
AFAIK Ich mache alles richtig, aber kann irgendjemand einen Grund für den Absturz erkennen? ? Ich neige dazu, es als Fehler gegen WebAuthenticator für iOS zu protokollieren, aber bevor ich etwas Dummes mache, „überprüfen Sie bitte meine Arbeit!“
