ASP.NET MVC4 Forms 登录验证

来源:转载

Web.config配置:

在<system.web>节下:

<authentication mode="Forms">

<forms loginUrl="~/Auth/Account/Login" timeout="2880" />

</authentication>

登录代码:

/// <summary>

/// 登录

/// </summary>

public static bool Login(string userName, string userPwd)

{

MySqlHelper dbHelper = new MySqlHelper();

sys_user userModel = dbHelper.FindBySql<sys_user>(string.Format("select * from Sys_User where UserName='{0}'", userName));

if (userModel != null)

{

if (userModel.userPwd.ToUpper() == MD5Helper.Encrypt(userPwd))

{

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(userName, false, 120);

string encryptedTicket = FormsAuthentication.Encrypt(ticket);

HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);

HttpContext.Current.Response.Cookies.Add(authCookie);

return true;

}

}

return false;

}

View Code

退出登录代码:

/// <summary>

/// 退出登录

/// </summary>

public static void LoginOut()

{

FormsAuthentication.SignOut();

}

View Code

判断用户是否登录:

/// <summary>

/// 判断是否登录

/// </summary>

public static bool IsLogin

{

get

{

return HttpContext.Current.User.Identity.IsAuthenticated;

}

}

View Code

获取登录用户:

/// <summary>

/// 获取登录用户

/// </summary>

public static sys_user LoginUser

{

get

{

if (HttpContext.Current.User.Identity.IsAuthenticated)

{

string cookieName = FormsAuthentication.FormsCookieName;

HttpCookie authCookie = HttpContext.Current.Request.Cookies[cookieName];

FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);

string userName = authTicket.Name;

MySqlHelper dbHelper = new MySqlHelper();

return dbHelper.FindBySql<sys_user>(string.Format("select * from SYS_USER where UserName='{0}'", userName));

}

return null;

}

}

View Code

Action跳过登录验证使用AllowAnonymous:

[AllowAnonymous]

public ActionResult Login()

{

return View();

}

View Code

需要登录验证的Controller使用Authorize,或者加在自己写的ControllerBase上:

[Authorize]

public class ControllerBase : Controller

View Code
