QuickFIX/n - SSL 启动器无 stunnel

如何解决QuickFIX/n - SSL 启动器无 stunnel

一直在用头撞墙。

我正在尝试设置一个 quickfix 启动器来建立到 Bloomberg FIX 服务器的 SSL 连接。并且基于 docs，我认为这将相对直接实现。但是，我似乎无法弄清楚我哪里出错了。任何帮助将不胜感激。

注意事项：

• 我正在使用 dotnet cli 创建、构建和运行项目
• 彭博为我们提供了 3 种格式的证书：JKS、PEM 和 PKCS12
• 我已经使用 this S/O comment (Convert PFX to CER) 中描述的过程从提供的 PKCS12 证书生成了生成的 mycerts.cer 文件。但是，无论是否执行此步骤，错误信息都是相同的
• 可能还值得注意的是，我之前已经设法使用 python 版本的 quickfix 和 stunnel（处理 SSL 连接）建立并维护到bloomberg FIX 服务器的安全连接。但是我现在需要移除对 stunnel 的依赖，因此尝试切换到 quickfix/n

设置：

这是当前的 .csproj 文件

<Project Sdk="Microsoft.NET.Sdk">

  <ItemGroup>
    <ProjectReference Include="..\Heimdall.AppTest\Heimdall.AppTest.csproj" />
  </ItemGroup>

  <ItemGroup>
    <packagereference Include="QuickFIXn.Core" Version="1.10.0" />
    <packagereference Include="QuickFIXn.FIX4.4" Version="1.10.0" />
  </ItemGroup>

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <copy SourceFiles=".\FIX44.xml" DestinationFolder="$(TargetDir)" />
    <copy SourceFiles=".\bbgetomsClient.cfg" DestinationFolder="$(TargetDir)" />
    <copy SourceFiles=".\pkcs12\cert.pfx" DestinationFolder="$(TargetDir)" />
    <copy SourceFiles=".\openssl\mycerts.cer" DestinationFolder="$(TargetDir)" />
  </Target>

</Project>

这是启动器应用程序使用的实际 bbgetomsClient.cfg 文件（基于 this issue）

这是超级基本的 program.cs

using System;
using System.Collections.Generic;
using System.Text;
using QuickFix;
using QuickFix.Fields;
using QuickFix.Transport;
using System.Linq;

namespace Heimdall.App
{
    public class MyQuickFixApp : IApplication
    {
        public void FromApp(Message msg,SessionID sessionID) 
        {
            Console.WriteLine("IN:<FromApp>  " + msg); 
        }
        public void OnCreate(SessionID sessionID) { }
        public void Onlogout(SessionID sessionID) { }
        public void Onlogon(SessionID sessionID) { }
        public void FromAdmin(Message msg,SessionID sessionID) 
        {
            Console.WriteLine("IN:<FromAdmin>  " + msg); 
        }
        public void ToAdmin(Message msg,SessionID sessionID) 
        {
            Console.WriteLine("OUT:<ToAdmin>  " + msg); 
        }
        public void ToApp(Message msg,SessionID sessionID) 
        {
            Console.WriteLine("IN:<ToApp>  " + msg); 
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            SessionSettings settings = new SessionSettings("bbgetomsClient.cfg");
            IApplication myApp = new MyQuickFixApp();
            IMessageStoreFactory storeFactory = new FileStoreFactory(settings);
            ILogFactory logFactory = new FileLogFactory(settings);
            Socketinitiator initiator = new Socketinitiator(
                myApp,storeFactory,settings,logFactory);

            try
            {


                initiator.Start();
                while (true)
                {
                    System.Threading.Thread.Sleep(2000);
                }
                

            }
            catch (System.Exception e)
            {
                Console.WriteLine("==Fatal error==");
                Console.WriteLine(e.ToString());
                initiator.Stop();
            }

        }
    }
}

错误：

使用上面列出的设置运行项目时，观察到以下错误：

据我所知，我的错误可能与this issue (.NetCore3.1 and QuickFIXn problem #571)
