我正在运行一个安装了Ubuntu 14.04.1 LTS x64的VPS。我已经安装了mono complete。我正在尝试创建一个简单的HTTPS侦听器,然后再进行更大的操作。这是我第一次使用Mono进行开发

下面是我的测试应用程序的完整代码:

namespace jvs
{
  using System;
  using System.Net;
  using System.Text;
  using System.Linq;
  using System.IO;

  class Host
  {
    public HttpListener Server { get; set; }
    public TextWriter Log { get; set; }

    public Host()
    {
      this.Server = null;
      this.Log = Console.Out;
    }

    public Host(TextWriter log)
    {
      this.Server = null;
      this.Log = log;
    }

    public void Start()
    {
      this.Server = new HttpListener();
      this.Server.Prefixes.Add("https://*:443/");
      this.Server.AuthenticationSchemes = AuthenticationSchemes.Basic;
      this.Server.Start();
      this.Server.BeginGetContext(this.OnContextReceived, this.Server);
      Log.WriteLine("Host started; listening on:");
      foreach (var prefix in this.Server.Prefixes)
      {
        Log.WriteLine("  {0}", prefix.ToString());
      }
    }

    public void Stop()
    {
      this.Server.Stop();
      this.Server = null;
    }

    private void OnContextReceived(IAsyncResult ar)
    {
      // This function is NEVER called
      var server = ar.AsyncState as HttpListener;
      var context = this.Server.EndGetContext(ar);
      var identity = context.User.Identity as HttpListenerBasicIdentity;
      var response = context.Response;
      Log.WriteLine("Connection received");
      Log.WriteLine("  User: {0}\n  Password: {1}", identity.Name, identity.Password);
      server.BeginGetContext(this.OnContextReceived, server);
      using (var ms = new MemoryStream())
      using (var w = new StreamWriter(ms) { AutoFlush = true })
      {
        w.WriteLine(
        @"<html>
        <head>
        <title>Vorpalnet</title>
        </head>
        <body>
        <div style=""text-align: center; vertical-align: middle; width: 100%; height: 80%"">
        it worked.
        </div>
        </body>
        </html>");
        var buffer = ms.ToArray();
        response.ContentLength64 = buffer.Length;
        response.OutputStream.Write(buffer, 0, buffer.Length);
        response.OutputStream.Close();
      }

    }

    public static void Main(string[] args)
    {
      Host host = new Host();
      host.Start();
      Console.Error.WriteLine("PID {0}", System.Diagnostics.Process.GetCurrentProcess().Id);
      while (true) { }
    }
  }
}
并核实:

$ httpcfg -list

$ sudo ./host.exe
Host started; listening on:
  https://*:443/
PID 15961
当它运行时,我打开了另一个会话并运行了
sudonetstat-antp | grep443
;这是输出:

tcp    0     0 0.0.0.0:443         0.0.0.0:*           LISTEN      15961/cli
我试图在本地连接到主机,但没有得到任何回报,这让我觉得mono没有获取证书:

$ openssl s_client -connect outpost:443
CONNECTED(00000003)
2348096:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:177:

我甚至通过host.exe.config启用了网络跟踪日志记录,mono似乎忽略了该日志记录,因为没有写入任何输出

应该注意,使用普通HTTP(“HTTP://*:80/”)根本没有问题。一切正常。不幸的是,我将需要HTTPS来实现此项目的最终目标

此时我几乎把头上剩下的头发都拔了出来。我在谷歌上搜索到的所有东西都有解决这个问题的Windows解决方案,但在Linux上没有什么有用的

这是单声道配置问题吗?有我错过的一步吗?我是否生成了错误的证书?

解决方案是:

$ sudo httpcfg -add -port 443 -cert outpost.cer -pvk outpost.pvk
原因:我正在通过
sudo
运行
host.exe
,以获得使用端口443的权限。因此,从
/root/.config/.mono/httplistener
而不是
/home/vps/.config/.mono/httplistener
中提取证书。通过
sudo
运行
httpcfg
,将证书放在正确的位置

这么简单的问题真让人头疼

$ sudo httpcfg -add -port 443 -cert outpost.cer -pvk outpost.pvk
