在使用 OAUTH 2.0 访问 Google Analytics 时尝试查找 ServiceAccountCredential.cs 文件的代码

Question

我正在尝试使用 OAUTH 2.0 身份验证访问 ga:visits 和 ga:transactions 的 Google Analytics（分析）数据。我已按照以下步骤操作：

1. 在https://code.google.com/apis/console/ 网站上启用了 Google Analytics API。另外，创建了一个客户端 ID 并保存了 .p12 密钥
2. 生成的电子邮件 ID 在 Analytics 网站上提供了读取和分析访问权限。
3. 我创建了一个 Windows 窗体应用程序，还使用 ​​package 命令下载了 NuGet 包：- Install-Package Google.Apis.Analytics.v3 包括 Google.Apis,Google.Apis.Analytics.v3,Google.Apis.Auth,Google.Apis.Auth.PlatformServices,Google.Apis.Core,Google.Apis.PlatformServices 在内的所有引用都添加到项目中

此外，在访问数据时遇到错误：-

查找来源 c:\code\google.com\google-api-dotnet-client\default\Tools\Google.Apis.Release\bin\Debug\test\default\Src\GoogleApis.Auth.DotNet4\OAuth2\ServiceAccountCredential.cs

当下面的代码行运行时：

var credential = new ServiceAccountCredential(new     ServiceAccountCredential.Initializer(serviceAccountEmail)         
 {    
    Scopes = new[] { AnalyticsService.Scope.AnalyticsReadonly }    
 }.FromCertificate(cert));   

你能帮我解决这个错误吗？ 请在下面找到使用的代码：-

        public Form1()

        }  

        private void Form1_Load(object sender, EventArgs e)
        {

            string keyFilePath = "C:\\Fetch GA Data-348e7435108b.p12";
            string serviceAccountEmail= "xx@developer.gserviceaccount.com";     
            string keyPassword = "notasecret";
            string websiteCode = "8482xxxx";     
            AnalyticsService service = null; 

            //loading the Key file     
            var certificate = new X509Certificate2(keyFilePath, keyPassword, X509KeyStorageFlags.Exportable);  

            //Add Scopes
            var scopes =     
            new string[] { AnalyticsService.Scope.Analytics,AnalyticsService.Scope.AnalyticsEdit,AnalyticsService.Scope.AnalyticsManageUsers,AnalyticsService.Scope.AnalyticsReadonly   
};       

            //create a new ServiceAccountCredential 
            var credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmail)     
            {
                //Scopes = scopes     
                Scopes = new[] { AnalyticsService.Scope.AnalyticsReadonly }

            }.FromCertificate(cert));    

            //Create a Service
            service = new AnalyticsService(new BaseClientService.Initializer()    
            {    
                HttpClientInitializer = credential    
            }); 


            DataResource.GaResource.GetRequest request = service.Data.Ga.Get(     
              "ga:" + websiteCode, "2015-05-27", "2015-05-27","ga:visits");     
            request.Dimensions = "ga:year,ga:month,ga:day";     
            var data = request.Execute();   

            }


        }
}

我不确定您从哪里获得该示例，但它甚至与您应该如何使用服务帐户来访问 Google Analytics（分析）api 的方式相差甚远。

 string[] scopes = 
          new string[] { 
             AnalyticsService.Scope.Analytics,                 // view and manage your Google Analytics data
             AnalyticsService.Scope.AnalyticsManageUsers};     // View Google Analytics data      

string keyFilePath = @"c:\file.p12" ;    // found in developer console
string serviceAccountEmail = "xx@developer.gserviceaccount.com";  // found in developer console
//loading the Key file
var certificate = new X509Certificate2(keyFilePath, "notasecret", X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential( new ServiceAccountCredential.Initializer(serviceAccountEmail)
                                                                  {
                                                                   Scopes = scopes
                                                                 }.FromCertificate(certificate));


AnalyticsService service = new AnalyticsService(new BaseClientService.Initializer()
            {
             HttpClientInitializer = credential,
             ApplicationName = "Analytics API Sample",
            });

从Google Analytics Authentication C#系列教程中翻录的代码

TIP 服务帐户设置

从 Google 开发者控制台获取服务帐户电子邮件地址，我们需要让此电子邮件地址访问我们的 Google Analytics（分析）数据。我们通过添加它来做到这一点，就像我们在 Google Analytics（分析）网站的管理部分中添加任何其他用户一样。将服务帐户电子邮件地址添加为帐户级别的用户，它必须是帐户级别。这将使您的服务帐户能够访问相关的 Google Analytics 帐户。我有没有提到它必须在帐户级别？
