.net MVC中使用forms验证

文件夹的分部是这样子的

首先在Web.config中设置

authentication和authorization 节点
 <system.web> <authentication mode="Forms"> <forms loginUrl="~/Login/Index" timeout="2880" defaultUrl="~/Home/Index"/> </authentication> <anonymousIdentification enabled="true"/> <authorization> <deny users="?"/> <!--拒绝匿名访问--> </authorization> <compilation debug="true" targetFramework="4.5" /> <httpRuntime targetFramework="4.5" /> <httpModules> <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" /> </httpModules> </system.web>

如果在Login文件夹还有不需要匿名访问,或者在LoginController中除了登陆还有方法可以匿名访问,

那么我们需要在加上这一个节点

 <location path="Login"> <!--这里的意思就是LoginController下的方法可以匿名访问--> <system.web> <authorization> <allow users="*" /> <!--允许匿名访问--> </authorization> </system.web> </location>

登陆的方法贴出一部分代码,仅供参考

 public bool ValidateUser(LoginVO model) { string encodePassword = MD5(model.PassWord);//加密 string sql = "select * from User_Users where ([email protected] or [email protected]) and [email protected]"; var user = Context.Data.Query<UsersPO>(sql, new {UserName = model.LoginName, JobNumber = model.LoginName, PassWord = encodePassword}).SingleOrDefault(); if (user == null) return false; DateTime expiration = model.IsRememberLogin //是否记住密码 ? DateTime.Now.AddDays(14) : DateTime.Now.Add(FormsAuthentication.Timeout); var ticket=new FormsAuthenticationTicket( 1,//指定版本号:可随意指定 user.UserName,//登录用户名:对应 Web.config 中 <allow users="Admin" … /> 的 users 属性 DateTime.Now, //发布时间 expiration,//失效时间 true,//是否为持久 Cookie user.UserId.ToString(), //用户数据:可用 ((System.Web.Security.FormsIdentity)(HttpContext.Current.User.Identity)).Ticket.UserData 获取 FormsAuthentication.FormsCookiePath //指定 Cookie 为 Web.config 中 <forms path="/" … /> path 属性,不指定则默认为“/” ); var encryptedTicket = FormsAuthentication.Encrypt(ticket); if (HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName] != null) { HttpContext.Current.Request.Cookies.Remove(FormsAuthentication.FormsCookieName); } var loginIdentify=new HttpCookie(FormsAuthentication.FormsCookieName); if (model.IsRememberLogin) { loginIdentify.Expires = DateTime.Now.AddDays(7); } loginIdentify.Value = encryptedTicket; HttpContext.Current.Response.AppendCookie(loginIdentify);//添加Cookie return true; } /// <summary> /// 加密 /// </summary> /// <param name="str"></param> /// <param name="encoding"></param> /// <param name="toUpper"></param> /// <param name="isReverse"></param> /// <param name="count"></param> /// <returns></returns> private string MD5(string str, Encoding encoding=null, int count = 1) { if (encoding == null) { encoding = Encoding.Default; } var bytes = new MD5CryptoServiceProvider().ComputeHash(encoding.GetBytes(str)); var md5 = string.Empty; for (int i = 0; i < bytes.Length; i++) { md5 += bytes[i].ToString("x").PadLeft(2, '0'); } if (count <= 1) { return md5; } return MD5(md5, encoding, --count); }
