用最简单的Session方式记录用户登录状态
1.添加DefaultController控制器,重写OnActionExecuting方法,每次访问控制器前触发

public class DefaultController : Controller { protected override void OnActionExecuting(ActionExecutingContext filterContext) { base .OnActionExecuting(filterContext); var controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName; var userName = Session[ "UserName" ] as String; if (String.IsNullOrEmpty(userName)) { //重定向至登录页面 filterContext.Result = RedirectToAction( "Index" , "Login" , new { url = Request.RawUrl}); return ; } } } |
2.登录控制器

public class LoginController : Controller { // GET: Login public ActionResult Index( string ReturnUrl) { if (Session[ "UserName" ] != null ) { return RedirectToAction( "Index" , "Home" ); } ViewBag.Url = ReturnUrl; return View(); } [HttpPost] public ActionResult Index( string name, string password, string returnUrl) { /* 添加验证用户名密码代码 */ Session[ "UserName" ] = name; if (Url.IsLocalUrl(returnUrl) && returnUrl.Length > 1 && returnUrl.StartsWith( "/" ) && !returnUrl.StartsWith( "//" ) && !returnUrl.StartsWith( "/\\" )) { return Redirect(returnUrl); } else { return RedirectToAction( "Index" , "Home" ); } } // POST: /Account/LogOff [HttpPost] public ActionResult LogOff() { Session[ "UserName" ] = null ; return RedirectToAction( "Index" , "Home" ); } } |
3.需要验证的控制器继承DefaultController

public class HomeController : DefaultController { public ActionResult Index() { return View(); } } |
这种方式适合比较小的项目
优点:简单,易开发
缺点:无法记录登录状态,而且Session方式容易丢失
