手动注册WebApi控制器

我认为HttpControllerSelector是正确的方法。

Http控制器选择器:

public class HttpControllerSelector : IHttpControllerSelector
{
    private readonly HttpConfiguration _httpConfiguration;

    public HttpControllerSelector(HttpConfiguration httpConfiguration)
    {
        this._httpConfiguration = httpConfiguration;
    }

    public HttpControllerDescriptor SelectController(HttpRequestMessage request)
    {
        return new HttpControllerDescriptor(this._httpConfiguration, 
                                            nameof(ValuesController), 
                                            typeof(ValuesController));
    }

    public IDictionary<string, HttpControllerDescriptor> GetControllerMapping()
    {
        var mapping = new Dictionary<string, HttpControllerDescriptor>
        {
            {
                nameof(ValuesController),
                new HttpControllerDescriptor(this._httpConfiguration,
                                             nameof(ValuesController),
                                             typeof(ValuesController))
            }
        };
        return mapping;
    }
}

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services
        config.Services.Replace(typeof(IHttpControllerSelector), new HttpControllerSelector(config));

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

因此,在HttpControllerSelector中,您可以做任何您想做的事情。举个简单的例子,这里有一个控制器,它总是被选中的。在这一点上,你可以使用一个工厂或适合你的东西。

希望这能给你一个想法怎么做,快乐编码!
