asp.net mvc项目创建WebApi简单例子

1、创建默认路由的映射。

namespace RedisDemo.App_Start
{
    public class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional });
        }
    }
}

2、在Global.asax的 Application_Start 方法中注册路由。（注册要在默认路由之前，WebApiConfig在RouteConfig之前）

public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            WebApiConfig.Register(GlobalConfiguration.Configuration);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
    }

3、新建ApiController，并访问http://localhost:47337/api/demo/getlist

public class DemoController : ApiController
    {
        public List<User> GetList()
        {
            var list = new List<User>
            {
                new Models.User { Id=, Age="", Name="张三", Sex=, UID= },
                new Models.User { Id=, Age="", Name="张四", Sex=, UID= },
                new Models.User { Id=, Age="", Name="张五", Sex=, UID= },
                new Models.User { Id=, Age="", Name="张六", Sex=, UID= }
            };
            return list;
        }
    }
