C# ASP.NET MVC项目内使用ApiController

1.在App_Start文件夹新建WebApiConfig.cs文件，建立webApi路由的注册方法。

using System.Web.Http;

namespace PrivilegeManager
{
    public class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.MapHttpAttributeRoutes();

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

2.修改Global.asax启动项，注册webApi路由（注意要在MVC路由之前注册）。

using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;

namespace PrivilegeManager
{
    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);//api路由注册要在mvc前面

            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);//mvc路由注册
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
    }
}

3.建立API Controller

using System;
using System.Collections.Generic;
using System.Web.Http;

namespace PrivilegeManager.Controllers
{
    public class DataApiController : ApiController
    {

        [HttpPost]
        //此方法实际访问地址：ip地址/api/DataApi/GetTest
        public Object GetTest(QueryCommon query)
        {
            //入参是json格式，会自动转成实体。返参的实体也会自动转成json格式
            list = List<实体>();
            return list;
        }


    }
}
