我正在尝试将HTTPS支持添加到我的简单Mono HTTP服务器中.它在大多数情况下都能正常运行，但是当发生SSL异常(例如客户端取消握手)时，应用程序将崩溃.显然，这样的事情不会完全崩溃，所以我需要以某种方式捕获该异常.
I'm trying to add HTTPS support to my simple Mono HTTP server. It works perfectly most of the time, but the application crashes when an SSL exception occurs, such as the client canceling the handshake. Obviously something like that shouldn't completely crash it, so I need to catch that exception somehow.
代码:
static void Main(string[] args) { try { var listener = new HttpListener(); string prefix = "*:8443/"; listener.Prefixes.Add(prefix); Console.WriteLine("Starting HTTP server at " + prefix); listener.Start(); while (true) { try { var context = listener.GetContext(); Console.WriteLine(context.Request.Url); } catch (Exception e) { Console.ForegroundColor = ConsoleColor.Red; Console.WriteLine("Exception processing request: " + e); Console.ResetColor(); } } } catch (Exception e) { Console.ForegroundColor = ConsoleColor.Yellow; Console.WriteLine("Exception caught! " + e); } }这是我遇到一个笨拙的客户端尝试连接时的日志:
Here's the log when I get a wonky client trying to connect:

并不是一个解决方案，但是我可以通过使用nginx创建本地反向代理并将单声道服务器设置为仅侦听127.0来解决此问题. .0.1
Not quite a solution, but I was able to work around the problem by creating a local reverse proxy with nginx, and setting the mono server to only listen on 127.0.0.1
