一旦过期，我无法刷新访问令牌。我不确定错误是什么，我按照文档的说法进行了操作。我正在使用WCF服务并获得以下错误。

                    }

我得到了解决方案。以下是更改...此外，我们必须在最初获取访问令牌时获取刷新令牌。

                    if (result.StatusCode == HttpStatusCode.OK)
                    {
                        var smessage = result.Content.ReadAsAsync<UserCredentials>(new[] { new JsonMediaTypeFormatter() }).Result;

                        if (smessage != null)
                        {

                            newToken = smessage.AccessToken;
                            expTime = smessage.ExpiresIn;
                            scope = smessage.Scope;
                            type = smessage.TokenType;
                            refToken = smessage.RefreshToken;
                        }
                    }
