c# - 来自 WCF 服务的 HttpWebRequest 失败并显示 - 请求已中止 : Could not create SSL/TLS secure channel

Question

我阅读了有关错误“请求已中止:无法创建 SSL/TLS 安全通道”的所有相关线程，但没有一个适用于我的情况。

我有一组针对 Splunk HTTP 事件收集器 REST API 执行的代码。如果我在我的机器上本地从控制台 C# 应用程序执行完全相同的代码，一切都会很好。

当我在 WCF 服务中执行它时，它失败并出现上述错误。由于 Splunk Light Cloud 服务使用的证书是自签名证书，因此我在执行代码之前设置了以下内容。

ServicePointManager.Expect100Continue = true;
ServicePointManager.CheckCertificateRevocationList = false;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
ServicePointManager.ServerCertificateValidationCallback = new
RemoteCertificateValidationCallback(
     delegate { return true; }
     );

我还尝试了 ServicePointManager.SecurityProtocol 下的不同选项，也选择了 SecurityProtocolType.Tls12，但没有成功。

错误似乎总是相同的。我启用了 System.Net 诊断跟踪，但这似乎没有帮助。我对其进行了修剪，以适应 stackoverflow 上的帖子限制。

值得注意的是，上述成功和失败的 SSL 跟踪的主要区别如下:

失败代码:

InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=IllegalMessage).

成功代码:

System.Net Information: 0 : [17520] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=ContinueNeeded).

知道无法向基于 https 的 RESTful 服务发出 HttWebRequest 的 WCF 服务有什么特别之处吗？

提前致谢!

Answer 1

我终于能够解决这个问题并为 future 的人们更新此页面。 为了理解这个问题，我集中调查了 3 个可能导致 IllegalMessage 响应的区域(Win32 SChannel native 错误代码:0x80090326)

1. Splunk 站点是否在其应用程序中使用了 ECC(椭圆曲线加密技术) 证书和我的服务器无法支持它
2. SSL 重新协商是否不起作用
3. 我的计算机生成的密码是否与证书预期不匹配

wireshark和microsoft消息分析器帮了一点忙，但是由于我没有Splunk证书的私钥，所以我无法解密很多内容。 Fiddler 和中间人代理也给了我一些有用的数据。

最终，#1 不再是问题。 #2 是一个问题，我发现 https://support.microsoft.com/en-us/help/2745582/.net-framework-4.5-hotfix-resolves-httpwebrequest-and-sslstream-issues 。考虑到这一点，我将计算机更新到 .NET 4.6.2

一旦我克服了所有其他问题，#3 就成了我的问题。根据这篇文章，https://technet.microsoft.com/en-us/library/dn786419(v=ws.11).aspx 、Windows Server 2012 R2 和 Win2k16 支持相同的 TLS 和密码套件。经过大量调试后，我发现我们的域策略有一个组策略，它限制了可用的密码，并根据您使用的操作系统要求特定的顺序。经过手动试验和错误后，我能够准确地找到 Splunk Light 公共(public)端点用于 HTTP 事件收集所需的 3 个密码:

TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P256 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P384 TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P384

事实上，我从 WCF 服务执行代码最终没有发挥任何作用。
