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 请求失败。请更新客户端使用的端点身份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 获得了一个令牌，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 上重现了该问题，代理上使用的证书在我的 PC 上是受信任的。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与我的问题很接近但不再适用（我在.Net 4.5中运行示例和服务器）： https: //support.microsoft.com/ zh-CN/kb/2564823

我错过了什么？

这是代码：

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

        TestServiceClient client = CreateClient(serverUrl, token);

        try
        {
            client.SearchSomething();

            Console.WriteLine("SearchSomething succeeded");
        }

正如我对问题所评论的那样：在花费大量时间寻找解决方案之后，由于服务器身份检查，具有安全模式“消息”的 WS2007FederationHttpBinding 似乎不适合在此上下文中使用。仍然可以在 SSL 卸载程序和服务标识上使用相同的证书。

这是我选择保留安全模型并解决我的问题的解决方案
