ABP之动态WebAPI(一)

ABP的动态WebApi实现了直接对服务层的调用（其实病没有跨过ApiController,只是将ApiController公共化，对于这一点的处理类似于MVC，对服务端的 调用没有跨过HttpHandler一样），这样不仅减少了ApiController的开发，也更能体现驱动领域设计的层结构。

 

AbpWebApiModule是Abp.Web.Api的模块类，该类中定义InitializeAspNetServices，InitializeRoutes两个方法，并且在模块的Initialize方法中执行，这两个方法分别是对WebApi的服务的替换与路由的配置，。这两处对WebApi的变更才使得直接调用服务层成为可能。

 

 

        private static void InitializeAspNetServices()
        {
            GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerSelector), new AbpHttpControllerSelector(GlobalConfiguration.Configuration));
            GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpActionSelector), new AbpApiControllerActionSelector());
            GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerActivator), new AbpControllerActivator());
        }

        private static void InitializeRoutes()
        {
            DynamicApiRouteConfig.Register();
        }

        public static void Register()
        {
            //Dynamic Web APIs (with area name)
            GlobalConfiguration.Configuration.Routes.MapHttpRoute(
                name: "AbpDynamicWebApi",
                routeTemplate: "api/services/{*serviceNameWithAction}"
                );
        }
