.net - WCF WS2007FederationHttpBinding 与 HTTPS

Question

我在尝试连接到 HTTPS 代理后面的 WCF API 时遇到以下错误:

名称为“CN=hostname”的服务器证书未能通过身份验证，因为其指纹(“X”)与端点身份(“Y”)中指定的指纹不匹配。因此，当前的 HTTPS 请求已失败。请更新客户端使用的端点标识或服务器使用的证书。

其中 X 是代理使用的证书的指纹，Y 是服务使用的证书的指纹

问题是我设法从 STS 获得了 token ，但之后我无法执行任何 Web 服务调用。

我通过使用本地 SSL 代理在我的 PC 上重现了这个问题，代理上使用的证书在我的 PC 上是可信的。使用 HTTP 时一切正常。

我搜索了几天的解决方案，我注意到这篇知识库文章接近我的问题但不再适用(我在 .Net 4.5 中运行示例和服务器):https://support.microsoft.com/en-us/kb/2564823

我错过了什么？

代码如下:

        Console.WriteLine("Token Received");
        Console.WriteLine(token);

        TestServiceClient client = CreateClient(serverUrl, token);

        try
        {
            client.SearchSomething();

            Console.WriteLine("SearchSomething succeeded");
        }
        catch (Exception e)

Answer 1

正如我对这个问题的评论:在花费大量时间搜索解决方案之后，由于服务器身份检查，似乎不打算在这种情况下使用安全模式为“消息”的 WS2007FederationHttpBinding。仍然可以在 SSL 卸载程序和服务身份上使用相同的证书。

这是我选择保留安全模型并解决我的问题的解决方案
