CryptographicException avec le fichier de service p12

Question

J'essaie de m'authentifier auprès de mon compte Google Analytics à l'aide d'un fichier de compte de service p12. Le code ci-dessous doit s'authentifier auprès de mon compte Google Analytics et demander les données dont j'ai besoin, mais je reçois une erreur avec le X509Certificate2 lorsque j'exécute le code ci-dessous. J'ai mis mon fichier p12 dans le dossier bin/debug de mon projet avec des informations d'identification données.

var certificate = new X509Certificate2(keyFilePath, keyPassword, X509KeyStorageFlags.Exportable); 

Je reçois l'erreur suivante:

Aidez-moi à ce sujet. Ce qui me manque ici. Toute aide est appréciée.

Answer 1

J'ai vu des problèmes avec le fichier P12 dans le passé. Je dois encore être en mesure de diagnostiquer complètement le problème. Parfois, il est simplement plus facile de charger le fichier .json du compte de service à la place. Google appelle p12 rétrocompatible de toute façon afin qu'ils puissent éventuellement cesser d'utiliser les fichiers p12.

C'est la méthode que j'utilise pour authentifier un compte de service. Il va déterminer lui-même quel type de fichier d'informations d'identification vous l'envoyez.

/// <summary> 
    /// Authenticating to Google using a Service account 
    /// Documentation: https://developers.google.com/accounts/docs/OAuth2#serviceaccount 
    /// </summary> 
    /// <param name="serviceAccountEmail">From Google Developer console https://console.developers.google.com</param> 
    /// <param name="serviceAccountCredentialFilePath">Location of the .p12 or Json Service account key file downloaded from Google Developer console https://console.developers.google.com</param> 
    /// <returns>AnalyticsService used to make requests against the Analytics API</returns> 
    public static AnalyticsService AuthenticateServiceAccount(string serviceAccountEmail, string serviceAccountCredentialFilePath) 
    { 
     try 
     { 
      if (string.IsNullOrEmpty(serviceAccountCredentialFilePath)) 
       throw new Exception("Path to the service account credentials file is required."); 
      if (!File.Exists(serviceAccountCredentialFilePath)) 
       throw new Exception("The service account credentials file does not exist at: " + serviceAccountCredentialFilePath); 
      if (string.IsNullOrEmpty(serviceAccountEmail)) 
       throw new Exception("ServiceAccountEmail is required."); 

      // These are the scopes of permissions you need. It is best to request only what you need and not all of them 
      string[] scopes = new string[] { AnalyticsReportingService.Scope.Analytics };    // View your Google Analytics data 

      // For Json file 
      if (Path.GetExtension(serviceAccountCredentialFilePath).ToLower() == ".json") 
      { 
       GoogleCredential credential; 
       using (var stream = new FileStream(serviceAccountCredentialFilePath, FileMode.Open, FileAccess.Read)) 
       { 
        credential = GoogleCredential.FromStream(stream) 
         .CreateScoped(scopes); 
       } 

       // Create the Analytics service. 
       return new AnalyticsService(new BaseClientService.Initializer() 
       { 
        HttpClientInitializer = credential, 
        ApplicationName = "Analytics Authentication Sample", 
       }); 
      } 
      else if (Path.GetExtension(serviceAccountCredentialFilePath).ToLower() == ".p12") 
      { // If its a P12 file 

       var certificate = new X509Certificate2(serviceAccountCredentialFilePath, "notasecret", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.Exportable); 
       var credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmail) 
       { 
        Scopes = scopes 
       }.FromCertificate(certificate)); 

       // Create the Analytics service. 
       return new AnalyticsService(new BaseClientService.Initializer() 
       { 
        HttpClientInitializer = credential, 
        ApplicationName = "Analytics Authentication Sample", 
       }); 

      } 
      else 
      { 
       throw new Exception("Unsupported Service accounts credentials."); 
      } 

     } 
     catch (Exception ex) 
     {

Utilisation:

var service = AnalyticsService AuthenticateServiceAccount(.....); 
DataResource.GaResource.GetRequest request = service.Data.Ga.Get(
       "ga:" + websiteCode, 
       DateTime.Today.AddDays(-15).ToString("yyyy-MM-dd"), 
       DateTime.Today.ToString("yyyy-MM-dd"), 
       "ga:sessions"); 
      request.Dimensions = "ga:year,ga:month,ga:day"; 
      var data = request.Execute(); 

      foreach (var row in data.Rows) 
      { 
       visitsData.Add(new ChartRecord(new DateTime(int.Parse(row[0]), int.Parse(row[1]), int.Parse(row[2])).ToString("MM-dd-yyyy"), int.Parse(row[3]))); 
      }
