DotNetOpenId —“此消息已被处理”错误（第 2 部分）

这已经被问过Here https://stackoverflow.com/questions/727838/dotnetopenid-this-message-has-already-been-processed-error，但不是我做的，OP接受了一个对我没有帮助的答案。到目前为止，我已经尝试从不同的浏览器登录、更改 Web 配置、清除 cookie 以及从外部计算机加载。

事实上，我最终发现这个问题是我自己的机器特有的；当我发布到另一台机器时，它工作得很好。关于在哪里寻找解决方案有什么建议吗？我故意使用了我能想到的最简单的测试代码，一个干净的空 aspx 页面和一个简单的Page_Load功能。

Edit：为了澄清，就像原始问题的作者一样，我收到“此消息已被处理”错误。这是打印到屏幕上的Response.Write(response.Exception.ToString());。我相信这个问题与配置相关，与其他作者不同，因为症状只出现在我的本地机器上。请注意，这些症状与我是否在运行代码的同一机器上进行测试无关。

    protected void Page_Load(object sender, EventArgs e)
    {
        using (OpenIdRelyingParty openid = new OpenIdRelyingParty())
        {
            IAuthenticationResponse response = openid.GetResponse();
            if (response != null)
            {
                try
                {
                    Response.Write(response.Exception.ToString());
                }
                catch (Exception)
                {
                }
                return;
            }
        }

        using (OpenIdRelyingParty openid = new OpenIdRelyingParty())
        {
            IAuthenticationRequest request = openid.CreateRequest(@"https://www.google.com/accounts/o8/id");
            request.RedirectToProvider();
        }

    }

在某些版本的 dotnetopenauth 中，您还可以获得：

此消息已经 处理。这可能表明 重放攻击正在进行中。

如果您的 maxAuthenticationTime 值太低（这显然与错误没有任何关系 - 但这是一个不同的问题）。我今天就经历过这个。

要增加此值，请编辑配置条目，如下所示https://github.com/DotNetOpenAuth/DotNetOpenAuth/wiki/Configuration https://github.com/DotNetOpenAuth/DotNetOpenAuth/wiki/Configuration（我建议设置为 0:10）。
