我已经用谷歌搜索了'今天这个问题的生命没有解决!

我正在尝试使用服务帐户构建一个非常简单的Google Analytics数据请求控制台应用。我已在Google Developers Console中设置了所有必需的详细信息,但我收到以下错误:

An unhandled exception of type 'Google.Apis.Auth.OAuth2.Responses.TokenResponseException'          
occurred in Google.Apis.dll

Additional information: Error:"invalid_grant", Description:"", Uri:""

以下是我的控制台应用程序中的代码(隐藏了密钥):

using System.Security.Cryptography.X509Certificates;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Analytics;
using Google.Apis.Analytics.v3;
using Google.Apis.Analytics.v3.Data;
using System;

namespace GoogleAnalyticsAPI
{

public class Program
{

    public static void Main(string[] args)
    {

        string profileId = "12345678";
        string serviceAccountEmail = "123456789abcdefghijklmnopq@developer.gserviceaccount.com";
        X509Certificate2 certificate = new X509Certificate2(@"PrivateKey.p12", "mypassword", X509KeyStorageFlags.Exportable);

        // Create credentials
        ServiceAccountCredential credential = new ServiceAccountCredential(
           new ServiceAccountCredential.Initializer(serviceAccountEmail)
           {
               Scopes = new[] { AnalyticsService.Scope.Analytics }
           }.FromCertificate(certificate));

        // Create the service
        var service = new AnalyticsService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = "Google Analytics API"

        });

        string startDate = "2014-07-01";
        string endDate = "2010-07-31";


        DataResource.GaResource.GetRequest request = service.Data.Ga.Get(string.Format("ga:{0}", profileId), startDate, endDate, "ga:visits, ga:newVisits");
        request.Dimensions = "ga:city";
        GaData data = request.Execute();

    }

}
}

非常感谢任何帮助!

事实证明,如果其他人有同样的问题我有错误的凭据:

  1. 仔细检查您是否使用服务帐户电子邮件结尾“@ developer.gserviceaccount.com”
  2. 检查下载的.p12文件是否位于您的调试文件夹中,并提供正确的私钥密码(在您创建服务帐户时提供给您)。
