WebAPI enables session function

The first step: simply create two classes to modify the routing method of WebApi The

first class, SessionRouteHandler, inherits from HttpControllerHandler, and implements the IRequiresSessionState interface. In fact, IRequiresSessionState has no internal methods, so there is no need to write anything.

public class SessionRouteHandler : HttpControllerHandler,IRequiresSessionState
 {
         public SessionRouteHandler(RouteData routeData) : base(routeData)
         {
         }
 }

The second class, SessionControllerRouteHandler, inherits from HttpControllerRouteHandler

public class SessionControllerRouteHandler : HttpControllerRouteHandler
 {
         protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
         {
             return new SessionRouteHandler(requestContext.RouteData);
         }
 }

After completing these two classes, you can move on to the next step.

Step 2: Modify WebApiConfig, give a hint to the novice, this class can be seen in Global, WebApiConfig.Register(... is in progress here. In general, in the App_Start directory. Since we want to make WebApi can obtain the Session set in the Controller in MVC, so this configuration needs to be changed.

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

             //Pass Session on Route
             RouteTable.Routes.MapHttpRoute(
                 name: "DefaultApi",
                 routeTemplate: "api/{controller}/{id}",
                 defaults: new {id = RouteParameter.Optional}).RouteHandler = new SessionControllerRouteHandler();

Well, after all is completed, it can be compiled. At this time, you can create a Session in the Controller in the normal way, for example:

Session["ValidCode"]="Session Test"
Then you can get it in WebApi:

HttpContext.Current. Session["ValidCode"].ToString() is
