webapi用session

在
Global.asax重写init函数（webapi默认不启用session）

public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
GlobalConfiguration.Configure(WebApiConfig.Register);

}
//启用session
public override void Init()
{
this.PostAuthenticateRequest += (sender, e) => HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required);
base.Init();
}
}

设置全局session

HttpContext.Current.Session.Add("userid", “hello”);
//HttpContext.Current.Session["userid"]="hello";

获取全局session

var lianglaing = HttpContext.Current.Session["userid"];
