我有一个类,我用Castle Dynamic Proxy代理它.我想为代理方法添加一些自定义属性(未在代理类中定义).这可能吗.
我想要这个,因为我想为我的应用程序的服务层生成ASP.NET Web API层.我代理服务(继承自ApiController和其他IMyService接口),它工作得很好但我想将WebAPI特定属性添加到这个新创建的Dynamic类中,因此Web API框架可以读取它们.
编辑:
如果有人想知道我想要什么,我想详细解释一下.
- public interface IMyService
- {
- IEnumerable<MyEntity> GetAll();
- }
- public class MyServiceImpl : IMyService
- {
- public IEnumerable<MyEntity> GetAll()
- {
- return new List<MyEntity>(); //TODO: Get from database!
- }
- }
- public class MyServiceApiController : ApiController,IMyService
- {
- private readonly IMyService _myService;
- public MyServiceApiController(IMyService myService)
- {
- _myService = myService;
- }
- public IEnumerable<MyEntity> GetAll()
- {
- return _myService.GetAll();
- }
- }
认为我有一个由MyServiceImpl实现的IMyService.我想让一个Api控制器能够从网上使用这项服务.
但是如你所见,api控制器只是实际服务的代理.那么,为什么我要写呢?我可以使用城堡windsor动态创建它.
这是我的想法,几乎在我的新项目(https://github.com/hikalkan/aspnetboilerplate)中完成.但是,如果我需要为api控制器的GetAll方法添加一些属性(例如Authorize),该怎么办呢?我不能直接添加,因为没有这样的类,它是城堡动态代理.
再次看到那个项目

我也想知道如何,以便我可以在IService和Route on Action上定义RoutePrefix.
幸运的是,我终于知道如何为代理定义自定义属性.
