自托管AspNet WebAPI与不同项目中的控制器类

我使用Visual Studio 2012(.NET Framework 4.5)创建了一个SelfHosted AspNet WebAPI。我为WebAPI启用了SSL。当控制器在同一个项目中定义时,它可以正常工作。

但是当我添加另一个包含控制器的项目的引用时,它会给我以下错误:

No HTTP resource was found that matches the request URI 'https://xxx.xxx.xxx.xxx:xxxx/hellowebapi/tests/'.

我为HttpSelfHostConfiguration和MessageHandler创建了自定义类。

解决这个问题的任何帮助对我来说都是一个很好的时间。

提前感谢。

您可以编写一个简单的自定义程序集解析程序,以确保加载引用的程序集以使控制器探测工作。

以下是菲利普关于此的一篇不错的帖子:

样品:

class Program
{
    static HttpSelfHostServer CreateHost(string address)
    {
        // Create normal config
        HttpSelfHostConfiguration config = new HttpSelfHostConfiguration(address);

        // Set our own assembly resolver where we add the assemblies we need
        CustomAssembliesResolver assemblyResolver = new CustomAssembliesResolver();
        config.Services.Replace(typeof(IAssembliesResolver), assemblyResolver);

        // Add a route
        config.Routes.MapHttpRoute(
          name: "default",
          routeTemplate: "api/{controller}/{id}",
          defaults: new { controller = "Home", id = RouteParameter.Optional });

        HttpSelfHostServer server = new HttpSelfHostServer(config);
        server.OpenAsync().Wait();

        Console.WriteLine("Listening on " + address);
        return server;
    }

    static void Main(string[] args)
    {
        // Create and open our host
        HttpSelfHostServer server = CreateHost("http://localhost:8080");

        Console.WriteLine("Hit ENTER to exit...");
        Console.ReadLine();
    }
}

public class CustomAssembliesResolver : DefaultAssembliesResolver
{
    public override ICollection<Assembly> GetAssemblies()
    {
        ICollection<Assembly> baseAssemblies = base.GetAssemblies();

        List<Assembly> assemblies = new List<Assembly>(baseAssemblies);

        var controllersAssembly = Assembly.LoadFrom(@"C:\libs\controllers\ControllersLibrary.dll");

        baseAssemblies.Add(controllersAssembly);

        return assemblies;
    }
}
