Question

我用Nancy创建了一些自托管，然后我希望应用程序作为服务运行。所以我用topshelf来构建它。然后，当我调试我的程序或运行.exe时，程序运行良好。但是当我安装.exe作为服务并启动服务时。我无法调用我用nancy创建的API（仅在浏览器中＃34;等待localhost ..＆＃34;不返回错误或成功）。是因为工作目录，线程还是其他什么？谢谢

这是我的代码： Program.cs

public class Program
{
    [STAThread]
    public static void Main()
    {
        var thread = new Thread(WorkerMethod);
        thread.SetApartmentState(ApartmentState.STA);
        thread.IsBackground = false;
        thread.Start();
    }

    public static void WorkerMethod(object state)
    {
        HostFactory.Run(x =>
        {
            x.Service<HostingAPI>(s =>
            {
                s.ConstructUsing(name => new HostingAPI());
                s.WhenStarted(tc => tc.Start());
                s.WhenStopped(tc => tc.Stop());
            });

            x.RunAsLocalSystem();
            x.SetDescription("Hardware hosting API");
            x.SetDisplayName("Hosting Services for Hardware");
            x.SetServiceName("Hardware Services");
        });
    }
}

CDM_Module（南希模块）

public class CDM_Module : NancyModule
{
    public CDM_Module()
    {
        try
        {
            Get["/CDM/Machine/Start"] = parameters =>
            {
                var ins = HostingAPI.Instance;
                bool result = ins.InitCDM_Thread();

                return Response.AsJson(result);
            };

            Get["/CDM/Machine/OpenGate"] = parameters =>
            {
                var ins = HostingAPI.Instance;
                bool result = ins.StartProcess_Thread();

                return Response.AsJson(result);
            };

            Get["/CDM/Machine/CloseGate"] = parameters =>
            {
                var ins = HostingAPI.Instance;
                bool result = ins.StopProcess_Thread();

                return Response.AsJson(result);
            };
        }
        catch
        {
        }
    }
}

HostingAPI.cs（启动和停止功能以及一个为API调用的函数）

编辑

已经尝试捕捉异常，但没有人抓住。我尝试评论Dummy.m_autoreset.WaitOne（）和Dummy.m_autoreset.Set（）。现在API工作但是InitCDM（）内的函数没有执行？在该功能中，我将一些库称为机器，而不是机器直接或通过事件处理程序提供反馈。我认为我使用AddEventCDM（）创建的eventhandler无法通过库访问，因为该线程不再可用？有什么建议吗？

Answer 1

尝试在Start（）方法中的新线程上启动NancyHost。在我的情况下，Start（）方法没有返回，因此无法作为Windows服务启动。

拥有Topshelf的Nancy在作为服务运行时不起作用？ C＃
