DotnetopenAuth拋出一個「的ProtocolException

Question

我想實現OpeinID登錄與ASP.NET MVC。我試圖按照http://blog.nerdbank.net/2008/04/add-openid-login-support-to-your-aspnet.html

下面是我設置的web.config

<dotNetOpenAuth> 
<messaging> 
    <untrustedWebRequest> 
     <whitelistHosts> 
      <add name="localhost" /> 
     </whitelistHosts> 
    </untrustedWebRequest> 
</messaging> 
<reporting enabled="false" /> 

給出的步驟

<system.net> 
<defaultProxy useDefaultCredentials="true"> 
    <proxy autoDetect="True" usesystemdefault="True"/> 
</defaultProxy> 

我得到 '的ProtocolException' 的說法當我嘗試創建請求時，'找不到openId end point'。

try 
{ 
    //ProtocolException is thrown 
    IAuthenticationRequest request = openID.CreateRequest(openid_identifier); 
    request.RedirectToProvider(); 
} 
catch (ProtocolException) 
{ 
    throw; 
} 

由Dotnetopenauth生成的日誌文件。 （我已經取代我的有效的用戶ID與<myopenid>）

    at DotNetOpenAuth.OpenId.RelyingParty.AuthenticationRequest.Create(Identifier userSuppliedIdentifier, OpenIdRelyingParty relyingParty, Realm realm, Uri returnToUrl, Boolean createNewAssociationsAsNeeded) 

然後我和提琴手檢查，我看到越來越不產生請求得到URI。似乎dotnetopenauth無法生成請求，並在那裏失敗。

任何人都可以幫我在這裏嗎？任何我缺少的東西？

我正在代理之後工作。

Answer 1

我所能建議的只是編寫一個簡單的C＃控制檯應用程序，它使用HttpWebRequest從您輸入到DotNetOpenAuth的OpenID URL下載頁面，以便您自己查看失敗並診斷防火牆出了什麼問題/代理設置。

Answer 2

我和你有同樣的問題，如果我刪除代理自動檢測，它工作。因此，在web.config中system.net部分，只有：

這種配置讓我從背後企業代理服務器以及與使用招工作。
