【问题描述】：

我正在尝试使用 ASP.NET MVC 实现 OpeinID 登录。我正在尝试按照http://blog.nerdbank.net/2008/04/add-openid-login-support-to-your-aspnet.html

中给出的步骤进行操作

下面是我的设置 web.config

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

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

我在尝试创建请求时收到“ProtocolException”提示“未找到 openId 端点”。

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

Dotnetopenauth 生成的日志文件。（我已将我的有效用户 ID 替换为 <myopenid>）

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

然后我检查了提琴手，我发现没有生成获取 URI 的请求。似乎 dotnetopenauth 无法生成请求并且在那里失败。

有人可以帮我吗？有什么我遗漏的吗？

我在代理后面工作。

【解决方案1】：

我只能建议您编写一个简单的 C# 控制台应用程序，该应用程序使用 HttpWebRequest 从您输入到 DotNetOpenAuth 的 OpenID URL 下载页面，这样您就可以自己查看故障，并诊断您的问题所在防火墙/代理设置。

【讨论】：

绝对是一件好事...不幸的是又发现了另一个问题:)

【解决方案2】：

我遇到了和你一样的问题，如果我删除了代理自动检测，它就可以工作。因此，在 web.config system.net 部分，只有：

此配置允许我在公司代理服务器后面工作以及使用 Fiddler。
