新建一个api控制器，vs2015中的选择：

mvc结构中webapi的使用_json

App_Start/WebApiConfig.cs的修改：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http.Formatting;
using System.Web;
using System.Web.Http;
using System.Web.Http.WebHost;
using System.Web.Routing;
using System.Web.SessionState;

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

            GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
            //默认返回 json  
            GlobalConfiguration.Configuration.Formatters.JsonFormatter.MediaTypeMappings.Add(
                new QueryStringMapping("datatype", "json", "application/json"));
            //返回格式选择 datatype 可以替换为任何参数   
            GlobalConfiguration.Configuration.Formatters.XmlFormatter.MediaTypeMappings.Add(
                new QueryStringMapping("datatype", "xml", "application/xml"));

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

            //新加的规则  
            config.Routes.MapHttpRoute(
                name: "DefaultApi2",
                routeTemplate: "api/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            ); 

            //新加的规则  
            config.Routes.MapHttpRoute(
                name: "DefaultApi1",
                routeTemplate: "api/{controller}/{action}",
                defaults: new { id = RouteParameter.Optional }
            );

Global文件的修改：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using System.Web.Http;
using System.Web.Http.WebHost;
using System.Web.SessionState;

namespace sccod
{
    public class MvcApplication : System.Web.HttpApplication
    {
        public override void Init()
        {
            //注册事件
            this.AuthenticateRequest += WebApiApplication_AuthenticateRequest;
            base.Init();
        }
        void WebApiApplication_AuthenticateRequest(object sender, EventArgs e)
        {
            //启用 webapi 支持session 会话
            HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required);
        }

        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);//注册api路由

控制器程序：

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


namespace sccod.Controllers
{
    public class OperatorController : ApiController
    {
        [System.Web.Http.HttpGet]
        [System.Web.Http.HttpPost]
        public object test()
        {
            if (HttpContext.Current.Session["user"] == null)
            {
                HttpContext.Current.Session["user"] = System.Web.HttpContext.Current.Session.SessionID;
            }
            var tem = new
            {
                t1 = 1,
                t2 = "ddf",
                t3 = DateTime.Now.ToString(),
                t4 = true,
                t5= HttpContext.Current.Session["user"]

            };
            return tem;
