如何使用MVC获得attributeExchange和/或simpleregistration?

我的头撞在墙上想 AttributeExchange 或 SimpleRegistration 使用 3.2.0.9257 version of DotNetOpenAuth .

以下是我所做的:

1. 从Github下载了3.2.0.9257标签
2. 已打开DotNetOpenAuth Visual Studio解决方案
3. 对OpenIDrelyingPartyMVC示例进行了更改

这些更改都在用户控制器的身份验证方法中。

我换了44号线,

return openid.CreateRequest(Request.Form["openid_identifier"]).RedirectingResponse.AsActionResult();

包括以下内容:

var request = openid.CreateRequest(Request.Form["openid_identifier"]);

// Add SimpleRegistration requests for Email and FullName
var sr = new ClaimsRequest();
sr.Email = DemandLevel.Request;
sr.FullName = DemandLevel.Request;
request.AddExtension(sr);

// Add AttributeExchange requests for Email and FullName
var ax = new FetchRequest();
ax.Attributes.Add(new AttributeRequest(WellKnownAttributes.Contact.Email));
ax.Attributes.Add(new AttributeRequest(WellKnownAttributes.Name.FullName));
request.AddExtension(ax);

return request.RedirectingResponse.AsActionResult();

(我还添加了dotnetopenauth.openid.extensions.attributeexchange和dotnetopenauth.openid.extensions.simpleregistration命名空间。)

然后,在同样的方法中,在“阶段3认证”之后,我尝试获得响应:

var sr = response.GetExtension<ClaimsResponse>();
var ax = response.GetExtension<FetchResponse>();

但是,这些响应总是空的。我尝试过谷歌、雅虎和myopenid。在所有情况下,身份验证都正常工作,但不会返回SimpleRegistration或AttributeExchange数据。

我做错什么了?
