OpenID“1.0 OpenID提供程序不允许未经请求的断言”错误

Question

我们正在尝试使用OpenID jQuery插件(如StackOverflow)和DotNetOpenAuth来实现OpenID (作为依赖方)。

我们不能让AOL工作。DotNetOpenAuth重定向使用http://openid.aol.com/{username}很好，但是当我们成功身份验证并将其重定向回站点时，将运行以下代码：(缩写)

using (OpenIdRelyingParty openid = new OpenIdRelyingParty())
{
    // Not sure if we want to stick with this, just trying to get it to WORK once
    openid.SecuritySettings.MinimumRequiredOpenIdVersion = ProtocolVersion.V10;
    openid.SecuritySettings.RejectUnsolicitedAssertions = false;

    IAuthenticationResponse resp = openid.GetResponse();

    // Results:
    // resp.Status == AuthenticationStatus.Failed
    // resp.Exception == DotNetOpenAuth.Messaging.ProtocolException
    // resp.Exception.Message == "Unsolicited assertions are not allowed from 1.0 OpenID Providers."
}

有人知道是什么导致的吗？我发现很难去寻找一个不请自来的断言。或者是关于AOL支持的OpenID版本的文档。

编辑:请求的log4net日志，如下所示：

Answer 1

我相信这里发生的事情是，用于创建身份验证请求的OpenIdRelyingParty实例处于无状态(“哑”)模式。也就是说，将null传递给它的构造函数，或者在其中一个ASP.NET控件上设置Stateless="true"。但是当身份验证响应返回时，您将使用一个在有状态模式下创建的OpenIdRelyingParty实例来处理该响应(您没有显式地将null传递给它的构造函数)。

这会导致身份验证响应不兼容。创建请求的安全性级别较低，因为该额外安全性所需的状态不可用。但是，当身份验证响应返回时，状态是可用的，因此安全性要求更高，并且拒绝对低级请求的响应。

最好只创建一个OpenIdRelyingParty实例，将其存储在某个静态字段中，然后将其用于所有登录。它是线程安全的，专门为此设计的。它将帮助您避免这类问题在未来，并成为一个更多的表现。

顺便说一句，我还希望您在创建OpenIdRelyingParty实例之后显式地设置它，否则我不认为无状态模式会允许使用AOL。站点上的无状态模式RP和OpenID 1.1提供程序是一个低安全性的组合，DotNetOpenAuth默认拒绝它，因为该协议很容易被重放攻击。这样你就可以知道你在做什么(如果你真的在这样做的话)。

(哇哦。在原木上挖了很多.)

Answer 2

“未经请求的断言”意味着您的应用程序认为AOL发送了带有id_res消息的人，而您的应用程序从未为该标识符执行checkid_setup。我将让安德鲁来说明DotNetOpenAuth是如何处理这个或AOL的。

(因为它在Python中工作。)
