webapi支持session

首先创建两个保存会话状态的类：SessionableControlHandler，SessionStateRouteHandler

代码如下

using System.Web.Http.WebHost;
using System.Web.Routing;
using System.Web.SessionState;

namespace iAssistantAPI.Authentication
{
    public class SessionableControlHandler : HttpControllerHandler, IRequiresSessionState
    {
        public SessionableControlHandler(RouteData routeData)
            : base(routeData)
        {
        }
    }
}

using System.Web;
using System.Web.Routing;

namespace iAssistantAPI.Authentication
{
    public class SessionStateRouteHandler : IRouteHandler
    {
        IHttpHandler IRouteHandler.GetHttpHandler(RequestContext requestContext)
        {
            return new SessionableControlHandler(requestContext.RouteData);
        }
    }
}

然后注册自己的 Route

打开RouteConfig，在RegisterRoutes 方法中的代码下，代码如下

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

此时webapi就可以支持 session 了
