Question

我正在尝试使用服务帐户p12文件向我的Google分析帐户进行身份验证。下面的代码应该对我的分析帐户进行身份验证并请求我需要的数据但是当我运行下面的代码时，我收到了X509Certificate2的错误。我已将我的p12文件放在我项目的bin / debug文件夹中，并带有给定的凭据。

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

我收到以下错误：

我的program.cs文件是

namespace GoogleAnalytics2
{
    class Program
    {
        static void Main(string[] args)
        {
           System.Console.WriteLine(ServiceAccountAuthExample.AuthenticateServiceAccount("analyticsdemo@ultimate-triode-151909.iam.gserviceaccount.com", "C:/Users/star/Downloads/CSharpApplication-9f9f557643f6.p12"));
        }
    }
}

对此有所帮助。我在这里失踪了什么。任何帮助表示赞赏。

Answer 1

过去我见过P12文件的问题。我还没有能够完全诊断出这个问题。有时它只是更容易下载服务帐户.json文件。 Google无论如何都在向后调用p12，因此他们最终可能会停止使用p12文件。

这是我用于验证服务帐户的方法。它会自行确定您发送的凭证文件类型。

    /// <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)
        {
            Console.WriteLine("Create service account AnalyticsService failed" + ex.Message);
            throw new Exception("CreateServiceAccountAnalyticsServiceFailed", ex);
        }
    }

从我的教程Google Service accounts with Json file

中删除了代码

用法：

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])));
            }

使用服务帐户p12文件的CryptographicException
