ASP.NET Identity教程三：（用户授权2）注销

在登录分布局更改方法路由

    using (Html.BeginForm("LogOff", "User", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))

　

在User控制器中增加方法

		//POST: /Account/LogOff
		[HttpPost]
		[ValidateAntiForgeryToken]
		public ActionResult LogOff()
		{

			AuthenticationManager.SignOut(DefaultAuthenticationTypes.ApplicationCookie);
			return RedirectToAction("Index", "Home");
		}


		// 用于在添加外部登录名时提供 XSRF 保护
		private const string XsrfKey = "XsrfId";

		private IAuthenticationManager AuthenticationManager
		{
			get
			{
				return HttpContext.GetOwinContext().Authentication;
			}
		}
