在Ubuntu VPS(14.04.1 LTS)上使用mono,为什么我的HTTPS HttpListener从未接收上下文?

我正在运行安装了Ubuntu 14.04.1 LTS x64的VPS。我已经安装了mono-complete。我在尝试更大的事情之前尝试创建一个简单的HTTPS侦听器。这是我第一次使用Mono进行任何开发。

以下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) { }
    }
  }
}

编译代码并运行它(通过sudo以允许使用端口443)后,一切似乎都没问题。但是,当我打开Firefox并导航到VPS地址时,我收到消息&#34;连接被中断。&#34;

此外,正如评论中所述,永远不会调用OnContextReceived

我已经生成了用于测试的自签名证书,并将它们配置为以下列方式使用:

$ makecert -r -n "CN=outpost" -sv outpost.pkv outpost.cer
$ httpcfg -add -port 443 -cert outpost.cer -pvk outpost.pvk

并验证:

$ httpcfg -list
Port: 443 Thumbprint: 02F57058BB31783710E6836E5646601A5AEBEB48
$ ll ~/.config/.mono/httplistener
total 16
drwxrwxr-x 2 vps vps 4096 Sep 17 16:42 ./
drwxrwxr-x 3 vps vps 4096 Sep 17 15:35 ../
-rw------- 1 vps vps  425 Sep 17 16:40 443.cer
-rw------- 1 vps vps  620 Sep 17 16:40 443.pvk
$ 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sudo netstat -antp | grep 443;这是输出:

tcp    0     0 0.0.0.0:443         0.0.0.0:*           LISTEN      15961/cli

我尝试在本地连接到主机并获得 nothing 作为回报,这使得单声道不会拿起证书:

$ 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,单声道似乎忽略了NO输出

$ cat host.exe.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.diagnostics>
    <sources>
      <source name="System.Net" tracemode="includehex" maxdatasize="1024">

          <add name="System.Net"/>
        </listeners>
      </source>
      <source name="System.Net.Cache">
        <listeners>

      <source name="System.Net.WebSockets">
        <listeners>
          <add name="System.Net"/>
        </listeners>

        initializeData="network.log"
      />
    </sharedListeners>
    <trace autoflush="true"/>
  </system.diagnostics>
</configuration>

应该注意的是,使用普通HTTP(&#34; http:// *:80 /&#34;)根本没有 no 问题。一切正常。不幸的是,我将需要HTTPS来实现这个项目的最终目标。

此时我几乎把剩余的头发从头上拉了下来。我用Google搜索的所有内容都在Windows上解决了这个问题,但在Linux上没有任何用处。

这是单声道配置问题吗?我缺少一个步骤吗?我生成的证书错了吗?

1 个答案:

答案 0 :(得分:1)

解决方案是:

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

原因:我通过host.exe运行sudo以获得使用端口443的权限。因此,证书是从/root/.config/.mono/httplistener而不是/home/vps/.config/.mono/httplistener提取的。通过httpcfg运行sudo会将证书放在正确的位置。

这么简单的问题令人头疼。
