【问题描述】：
我意识到以前有人问过这个问题，但几乎没有示例代码，所以我再次问，但至少有一点方向。
经过几个小时的搜索，我想出了以下部分实现。
namespace GoogleAnalyticsAPITest.Console
{
using System.Security.Cryptography.X509Certificates;
using DotNetOpenAuth.OAuth2;
using Google.Apis.Analytics.v3;
using Google.Apis.Analytics.v3.Data;
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
class Program
{
static void Main(string[] args)
{
log4net.Config.XmlConfigurator.Configure();
string Scope = Google.Apis.Analytics.v3.AnalyticsService.Scopes.Analytics.ToString().ToLower();
string scopeUrl = "https://www.googleapis.com/auth/" + Scope;
const string ServiceAccountId = "nnnnnnnnnnn.apps.googleusercontent.com";
const string ServiceAccountUser = "nnnnnnnnnnn@developer.gserviceaccount.com";
AssertionFlowClient client = new AssertionFlowClient(
GoogleAuthenticationServer.Description, new X509Certificate2(@"7039572692013fc5deada350904f55bad2588a2a-privatekey.p12", "notasecret", X509KeyStorageFlags.Exportable))
{
Scope = scopeUrl,
ServiceAccountId = ServiceAccountId//,ServiceAccountUser = ServiceAccountUser
};
IAuthorizationState state = AssertionFlowClient.GetState(client);
AnalyticsService service = new AnalyticsService(authenticator);
string profileId = "ga:xxxxxxxx";
string startDate = "2010-10-01";
string endDate = "2010-10-18";
string metrics = "ga:visits";
DataResource.GaResource.GetRequest request = service.Data.Ga.Get(profileId, startDate, endDate, metrics);
request.Dimensions = "ga:date";
GaData data = request.Fetch();
}
}
}
我有几个问题。对 AssertionFlowClient.GetState(client) 的调用会导致“invalid_scope”响应，如在
2012-10-19 13:27:36,272 (GMT-4) [8] 信息 DotNetOpenAuth - DotNetOpenAuth，版本=4.0.0.11165，文化=中性，PublicKeyToken=2780ccd10d57b246（官方） 2012-10-19 13:27:36,284 (GMT-4) [8] 调试 DotNetOpenAuth.Messaging.Channel - 准备发送 AssertionFlowMessage (2.0) 消息。 2012-10-19 13:27:36,294 (GMT-4) [8] 信息 DotNetOpenAuth.Messaging.Channel - 为https://accounts.google.com/o/oauth2/token 准备传出 AssertionFlowMessage (2.0) 消息： grant_type：断言 断言类型：http://oauth.net/grant_type/jwt/1.0/bearer 断言：（这里是一堆编码字符）

我尝试指定 ServiceAccountId 和 ServiceAccountUser 中的一个或两个，但没有成功。
其次，即使我获得了 IAuthorizationState，我也不确定如何获得可以传递给 AnalyticsService 构造函数的 IAuthenticator。
以下是我用来启用 DotNetOpenAuth 日志记录的 web.config。
