ASP.NET MVC应用程序的自托管-Java 学习之路

我有一个完整的ASP.NET MVC应用程序（由5个程序集组成，.NET 4.5.1，ASP.NET MVC 5.2.2），它在Visual Studio（使用IISExpress）中运行良好 .

我现在想要一个控制台应用程序，它接受MVC应用程序并托管它（自托管） .

我尝试使用 Microsoft.Owin.Host.HttpListener 和 Nancy.Owin 但是当我得到404页面时，我的配置缺少映射到我的MVC应用程序 .

我有

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.UseNancy();
    }
}

和

static void Main(string[] args)
    {
        StartOptions so = new StartOptions("http://localhost:9000/");
        using (WebApp.Start<Startup>(so))
        {
            Console.WriteLine("Press Enter to Exit");
            Console.ReadLine();
        }
    }

但显然缺少从正在运行的MVC应用程序中使用 MyMvcApplication 的配置 . 怎么做？或者如何自我托管呢？

我在网上找到的答案是指旧版本，我希望今天有更简单的方法 .

由于ASP.NET vNext尚不可用且我的应用程序使用MVC5，我必须将MVC应用程序完全迁移到Nancy或类似的东西 . MVC5过于依赖IIS .

为了解决这个问题，我决定采用中间解决方案，因为性能不是问题：

我的控制台应用程序创建IIS配置文件并启动IIS express：

// start IIS
        bool systray = Debugger.IsAttached;
        ProcessStartInfo psi = new ProcessStartInfo(iisExecutable, String.Format("/config:\"{0}\" /site:Ecm2.Web /trace:info /systray:{1}", configFile, systray));
        psi.UseShellExecute = false;
        psi.RedirectStandardInput = false;
        psi.RedirectStandardOutput = true;
        psi.RedirectStandardError = true;
        psi.CreateNoWindow = true;

        if (this.iisProcess != null) throw new NotSupportedException("Multiple starts not supported");
        this.iisProcess = new Process();
        this.iisProcess.StartInfo = psi;
        this.iisProcess.ErrorDataReceived += OnErrorDataReceived;
        this.iisProcess.OutputDataReceived += OnOutputDataReceived;
        this.iisProcess.Start();
        this.iisProcess.BeginErrorReadLine();
        this.iisProcess.BeginOutputReadLine();

如果有人想，这是“停止”片段的一部分：

if (this.iisProcess == null) throw new Exception("Does not look like there was something started yet!");

        if (this.iisProcess.HasExited)
        {
            log.WarnFormat("IIS has already exited with code '{0}'", this.iisProcess.ExitCode);
            this.iisProcess.Close();
            return;
        }

        log.InfoFormat("Stopping IIS instance #{0}", this.instanceId);
        ProcessCommunication.SendStopMessageToProcess(this.iisProcess.Id);
        bool exited = this.iisProcess.WaitForExit(30000);
        if (!exited)
        {
            log.WarnFormat("Failed to stop IIS instance #{0} (PID {1}), killing it now", this.instanceId, this.iisProcess.Id);
            this.iisProcess.Kill();
        }

        this.iisProcess.Close();

要停止普通的iis进程，你应该向它发送WM_QUIT . 这可能对此有所帮助：

/// <summary>
    /// Sends a WM_QUIT message to another process.
    /// </summary>
    /// <param name="pid">PID of the other process</param>
    public static void SendStopMessageToProcess(int pid)
    {
        log.DebugFormat("Sending stop message to PID #{0}", pid);
        try
        {
            for (IntPtr ptr = NativeMethods.GetTopWindow(IntPtr.Zero); ptr != IntPtr.Zero; ptr = NativeMethods.GetWindow(ptr, 2))
            {
                uint num;
                NativeMethods.GetWindowThreadProcessId(ptr, out num);
                if (pid == num)
                {
                    HandleRef hWnd = new HandleRef(null, ptr);
                    NativeMethods.PostMessage(hWnd, 0x12, IntPtr.Zero, IntPtr.Zero);
                    return;
                }
            }
        }
        catch (ArgumentException ex)
        {
            log.Error(String.Format("Failed to send WM_QUIT to PID #{0}", pid), ex);
        }
    }

    /// <summary>
    /// Provides the native methods to post messages to other windows processes.
    /// </summary>
    internal class NativeMethods
    {
        // Methods
        [DllImport("user32.dll", SetLastError = true)]
        internal static extern IntPtr GetTopWindow(IntPtr hWnd);
        [DllImport("user32.dll", SetLastError = true)]
        internal static extern IntPtr GetWindow(IntPtr hWnd, uint uCmd);
        [DllImport("user32.dll", SetLastError = true)]
        internal static extern uint GetWindowThreadProcessId(IntPtr hwnd, out uint lpdwProcessId);
        [DllImport("user32.dll", SetLastError = true)]
        internal static extern bool PostMessage(HandleRef hWnd, uint Msg, IntPtr wParam, IntPtr lParam);
    }
