讓Web API支援Session存取

• 參照：
  • Adding Session support to ASP.NET Web API

• 檔案: App_Start\WebApiConfig.cs

using System;
using System.Web.Http;
using System.Web.SessionState;
using System.Web.Http.WebHost;
using System.Web.Routing;
using System.Web;
 
namespace MvcApp1
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            RouteTable.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
 
            ).RouteHandler = new SessionRouteHandler();
        }
    }
 
    public class SessionControllerHandler : HttpControllerHandler, IRequiresSessionState
    {
        public SessionControllerHandler(RouteData routeData)
            : base(routeData)
        { }
    }
 
 
    public class SessionRouteHandler : IRouteHandler
    {
        IHttpHandler IRouteHandler.GetHttpHandler(RequestContext requestContext)
        {
            return new SessionControllerHandler(requestContext.RouteData);
        }
    }
}

• 使用時用 System.Web.HttpContext.Current.Session["變數名稱"]

或是 System.Web.SessionState.HttpSessionState Session = System.Web.HttpContext.Current.Session;
