1、在web.config的system.web节点增加authentication节点,定义如下:
2,新增AccountController。
public class AccountController : Controller { // 用于初期表示用 public ActionResult Login() { return View(); } // 登录按钮 [HttpPost] public ActionResult Login(string username, string password, string returnUrl) { bool result = FormsAuthentication.Authenticate(username, password); if (result) { FormsAuthentication.SetAuthCookie(username, false); return Redirect(returnUrl ?? Url.Action("Index", "Admin")); } else { ModelState.AddModelError("", "Incorrect username or password"); return View(); } } }
@{ Layout = null;}@using (Html.BeginForm()) { @Html.ValidationSummary() }
4、浏览器输入http://localhost:44324/Account/Login,输入web.config中定义的用户名和密码,成功就会进入Admin/Index页面。
5、其他页面如何进行认证?
1)在action中加Request.IsAuthenticated判断
public class AdminController : Controller { // GET: Admin public string Index() { if (!Request.IsAuthenticated) { FormsAuthentication.RedirectToLoginPage(); } return "welcome to Admin page!"; } }
2)在action方法上加Authorize特性
public class AdminController : Controller { // GET: Admin [Authorize] public string Index() { return "welcome to Admin page!"; } }
3)在controller上加Authorize特性(所有的action都会应用上)
[Authorize] public class AdminController : Controller { // GET: Admin public string Index() { return "welcome to Admin page!"; } }
