万能的csdn，求OAuth2.0的问题？

Question

做过，但是好像客户端不需要实现IAuthenticationClient啊

Answer 1

请问您是怎么处理的呢？我随便写了几句代码，服务端是有反应了，不过提示是 
he callback URL (http://localhost:29638/Account/ExternalLogin?ReturnUrl=) is not allowed for this client.client的代码：
public void RequestAuthentication(HttpContextBase context, Uri returnUrl)
        {
            Client = new WebServerClient(authServerDescription, "123", "test456");
            // Check to see if we're receiving a end user authorization response.
            var authorization = Client.ProcessUserAuthorization(context.Request);
            if (authorization != null)
            {
                // We are receiving an authorization response.  Store it and associate it with this user.
                Authorization = authorization;                context.Response.Redirect(context.Request.Path); // get rid of the /?code= parameter
            }
            else
            {
                Client.RequestUserAuthorization();
            }            if (Authorization != null)
            {                if (Authorization.AccessTokenExpirationUtc.HasValue)
                {
                    TimeSpan timeLeft = Authorization.AccessTokenExpirationUtc.Value - DateTime.UtcNow;                }
            }
        }
