In C#/Mono, nicht in der Lage, mit Google Cloud-Speicher zu kommunizieren

Question

Ich entwickle gerade eine C# -App, die auf Linux-Instanzen über Mono läuft. Sie müssen Bilder in Google Cloud Storage speichern, wenn sie verarbeitet wurden.

Ich habe die Authentifizierung Credentials-Setup und die .NET-Client-Bibliothek kann das StorageService-Objekt einrichten (d. H. Die JSON-Datei finden und alles validieren). Als ich versuchte hochzuladen, passierte nichts. In meiner SetupConnection() Funktion habe ich versucht, den einzelnen Bucket, den ich in meinem Projekt habe, abzufragen. Ich habe diesen Fehler:

Unhandled Exception:

Hier ist mein Setup-Code:

public static void SetupGCSConnection() 
{ 
    var credentials = Google.Apis.Auth.OAuth2.GoogleCredential.GetApplicationDefaultAsync().Result; 

    if (credentials.IsCreateScopedRequired) 
     credentials = credentials.CreateScoped(new[] { StorageService.Scope.DevstorageFullControl }); 

    var serviceInitializer = new BaseClientService.Initializer() 
    { 
     ApplicationName = "MyApp", 
     HttpClientInitializer = credentials 
    }; 

    storage = new StorageService(serviceInitializer); 

    // Error is thrown here 
    var buckets = storage.Buckets.List(Config.GoogleProjectID).Execute(); 
    foreach (var b in buckets.Items) { 
     Console.WriteLine(b.ToString()); 
    } 
} 

Ich habe in der Lage gewesen, bevor C# sprechen GCS, aber das war, als ich in einer Windows-Umgebung arbeitete, mit Microsoft .NET vm. Ich habe vorher ein wenig recherchiert und es könnte einige Probleme damit geben, wie Mono mit CAs im Gegensatz zu Microsofts VM zurechtkommt.

Answer 1

Ihr Problem kommt normalerweise von den Stammzertifikaten, die nicht aktualisiert werden.

Befolgen Sie die Anweisungen here, um Ihre Stammzertifikate zu aktualisieren.

Wenn das nicht dann hilft Ihnen, einen Delegierten zu

ServicePointManager.ServerCertificateValidationCallback 

einstellen und übernehmen Sie alle Zertifikate. Wenn das funktioniert, dann wissen Sie, dass das Problem bei der Zertifikatsüberprüfung liegt und Sie können eine andere Lösung ausprobieren. (Ich würde NIEMALS empfehlen, den Rückruf zu verwenden, um alle Zertifikate in der Produktion zu akzeptieren, verwenden Sie es einfach, um Ihr Problem zu debuggen).

Answer 2

Ich habe das Problem behoben.

Ich verwendete die Standard-Mono-Version, die mit Ubuntu geliefert wurde, und es war veraltet. Ich wechselte zu den offiziellen Mono-Repositories hier: http://www.mono-project.com/docs/getting-started/install/linux/

Und dann installiert das ca-certificates-mono Paket auch. (Weitere Details hier: http://www.mono-project.com/docs/faq/security/)

Dank Lex Li für die Hilfe.
