C# 尝试通过oauth进行身份验证时拒绝访问

我可以通过从浏览器获取身份验证令牌并稍后使用“获取…”来获得访问权限。 但是我想在没有用户干预的情况下完成它。 我决定使用服务帐户。 但当我试图进入时， 我总是收到“拒绝访问”。 我正在使用

var oAuth2Provider =
                (user.OAuthProvider as AdsOAuthProviderForServiceAccounts);
        oAuth2Provider.GenerateAccessTokenForServiceAccount();

oAuth2Provider的属性包括：

JwtCertificatePassword“notasecret”
JwtCertificatePath“D://xxxxx-privatekey.p12”
PrnEmail“jrusearchbroadtwomycc@gmail.com“//这是我的mcc帐户 已批准的开发令牌
ServiceAccountEmail“2222222-ckvf630rcccn3j7jjuf4fmujnbiotett@developer.gserviceaccount.com"

下面是错误的堆栈跟踪

然后我读到了关于谷歌应用程序账户的需求。 我已经注册，从我的服务帐户添加到它的帐户cliend id

22222222-CKVF630RCCCN3J7JJUF4FMUJNBiottet.apps.googleusercontent.com 范围：

但我再次被拒绝访问

然后我尝试使用另一个lib `

那我就试着

oAuth2Provider.AccessToken = access_token;

但再次拒绝接收访问

我已经试着解决这个问题一个星期了。

你真正想要完成的不是100%明显，但是如果你需要代表用户进行脱机访问，你可能需要的是一个“刷新令牌”，这样你可以在初始令牌过期时获得一个新的访问令牌。信息位于

我正在尝试在没有用户干预的情况下访问。它将每晚在我们的服务器上启动。所以我没有访问权，也没有机会手动获取访问令牌。有人能帮我解决我的问题吗？？？你找到解决方案了吗？我解决了。我现在正在使用google apps帐户检索api的访问权限。我已将此帐户注册为我的客户中心。我也是，但有一个不同的问题：将范围设置为

https://adwords.google.com/api/adwords

不带尾随斜杠，如图所示。结果证明，后面的斜杠是个大问题。

var result = GetAccessToken(SERVICE_ACCOUNT_EMAIL, SERVICE_ACCOUNT_PKCS12_FILE_PATH, SCOPE_ANALYTICS_READONLY);
            string access_token;
            result.TryGetValue("access_token", out access_token);

oAuth2Provider.AccessToken = access_token;
