我们有一个在服务器上运行的 Web 应用程序，它通过 XDomainRequest(由于 IE9)发布 http 请求。

有很多客户端计算机有一个控制台应用程序通过套接字监听器监听端口。客户端使用他们的打开 Web 应用程序 IE9 浏览器，当他们点击链接时，网页发送这样的请求:

"https://localhost:portNumber/applicationName/doSomething " “https://computerName:portNumber/applicationName/doSomething” "https://ipAddress:portNumber/applicationName/doSomething "

第二个和第三个请求是针对其他用户计算机的控制台应用程序发出的。

问题是，如果请求来自本地主机，控制台应用程序在读取传入数据和发回响应方面没有问题。但 如果请求带有计算机名称或 IP 地址，则浏览器会显示认证警告并希望用户单击 “继续访问此网站(不推荐)”链接。

我们想通过代码创建三个不同的证书。 但即使将 sslstream 与其中三个一起使用也是可能的，我们无法决定选择真正的认证，因为我们先进行身份验证，然后再接收数据。因此，当我们捕获传入请求时，身份验证必须已经完成。

另一种方法是强制套接字监听器或 sslstream 将所有这三个请求视为本地主机。因此，对于每一个身份验证，都将作为本地主机进行。但我找不到真正的方法。

这是代码。我给出代码是因为 SslStream 可能有一些错误的用法。

最佳答案

您的保安人员是对的。您尝试实现此目的的方式不适用于 SSL。

如果你有证书，它被设置为验证一个CN。因此，对于一个过于简单的例子。谷歌有证书。它验证 https://*.google.com。这意味着对 google.com 的任何请求都具有有效证书。你的浏览器很高兴。

现在打开命令提示符，ping google.com。获取 ip 地址(在我的例子中是 216.58.210.14)。输入 https://216.58.210.14 .您的浏览器提示该站点不安全等。原因是该服务器可能与您先前请求的服务器相同，但根据证书，您访问它的方式无效，因为 CN 不是谷歌。 com，而是一个 IP 地址。

因此，如果您有需要连接到(例如)127.0.0.1、10.92.1.4 和 myserver.com 的服务，您将需要一个对每种情况都有效的证书。
