未设置OAuth2Client clientId和clientSecret

我已经设置了一个可工作的IdentityServer 3，除了我试图添加的刷新令牌外，一切都很好。

我避免报告整个代码，因为我认为我发现了错误

var tokenClient = new OAuth2Client(new Uri("https://myServer/myIdentityServer/connect/token"), "clientId", "secretWord");
var response = await tokenClient.RequestAuthorizationCodeAsync(n.Code, n.RedirectUri);

我在第二行中得到一个错误，在调试中我发现tokenClient变量包含一些设置为null但不应该是的私有属性

_地址：{https://myServer/myIdentityServer/connect/token}

_authenticationStyle：无

_客户端：｛System.Net.Http.HttpClient｝

_clientId:空

_clientSecret：空

为什么_clientId和_clientSecret设置为null？我直接把这两个参数给了OAuth2Client构造函数，我是不是做错了什么？

更新：根据Scott Brady的建议，我也尝试了IdentityModel中的TokenClient类。没有任何更改，response变量报告HttpError"Internal Server Error"。

从IdentityServer方面来看，一切似乎都很好，请求第一部分的日志是好的

IdentityServer方面的响应还可以，我不明白为什么客户端出现内部服务器错误。
