.net - 让 claim 响应与 DotNet OpenId 配合使用的秘诀是什么？

Question

让 ClaimsResponse 与 DotNetOpenId 配合使用的秘诀是什么？ ？

例如，在这段代码(来自 Scott Hanselman's blog )中，ClaimsResponse 对象应该有很多不错的小东西，例如“昵称”和“电子邮件地址”，但 ClaimsResponse 对象本身是“null”:

 OpenIdRelyingParty openid = new OpenIdRelyingParty();  
 if (openid.Response != null)  
 {  
    // Stage 3: OpenID Provider sending assertion response  
    switch (openid.Response.Status)  
    {  
       case AuthenticationStatus.Authenticated:  
          ClaimsResponse fetch = openid.Response.GetExtension(typeof(ClaimsResponse)) as ClaimsResponse;  
          string nick = fetch.Nickname;  
          string homepage = openid.Response.ClaimedIdentifier;  
          string email = fetch.Email;  
          string comment = Session["pendingComment"] as string;  
          string entryId = Session["pendingEntryId"] as string;  
          if (String.IsNullOrEmpty(comment) == false && String.IsNullOrEmpty(entryId) == false)  
          {  
             AddNewComment(nick, email, homepage, comment, entryId, true);  
          }  
          break;  
    }  
 }  

起初，我认为这是因为我没有使用“ClaimsRequest”重定向到提供程序...但使用此代码重定向到 OpenId 提供程序仍然没有帮助:

OpenIdRelyingParty openid = new OpenIdRelyingParty();  
IAuthenticationRequest req = openid.CreateRequest(openid_identifier.Text);  
ClaimsRequest fetch = new ClaimsRequest();  
fetch.Email = DemandLevel.Require;  
fetch.Nickname = DemandLevel.Require;  
req.AddExtension(fetch);  
req.RedirectToProvider(); 

我做错了什么？或者其他开发者也经历过同样的痛苦吗？

我不知道你是否解决了问题，但我经过几个小时的努力找到了解决方案。实际上，您需要更改 web.config 文件以声明电子邮件和全名这是适合我的 web.config 。我从 nerddinner 项目下载了它。实际上，我复制了除 web.config 之外的所有内容，但没有收到电子邮件字段。所以后来我发现还有什么不对劲的地方。我从 nerddinner 项目复制了 web.config，一切正常。

如果你不想去 nerddinner 项目，这里是文件。
