ASP.NET MVC form验证

网站结构

webconfig

设置为form验证, 并拒绝所有的匿名用户

    <authentication mode="Forms">

      <forms loginUrl="~/Account/Index" timeout="2880" path="/" />

    </authentication>

    <authorization>

      <deny users="?"/>

    </authorization>

如果我们徐凯开放首页比如说Home/Index,那么做如下配置. 如果是Home文件夹下所有的页面都能访问, 那么 path=”Home”即可
<location path="Home/Index">
    <system.web>
      <authorization>
        <allow users="*" />
      </authorization>
    </system.web>
  </location>

cookie

启动程序, 来到登录页面. 如果登录成功, 那么我们需要写入cookie.

登陆页面

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<mvc安全验证.Models.User>" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>Index</title>

</head>

<body>

    <div>

         <% using( Html.BeginForm()){%>

         登录

         <%: Html.TextBoxFor(m => m.UserName, new { @class = "log" })%>

         <%: Html.TextBoxFor(x => x.RealName) %><br />

         <input type="submit" value="login" />

         <%};%>

    </div>

</body>

</html>

处理方法

[HttpPost]
        public ActionResult Index(Models.User model) {
            if (model.UserName == "admin")
            {
                //创造票据
                FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(model.UserName, false, 1);
                //加密票据
                string ticString = FormsAuthentication.Encrypt(ticket);
                //输出到客户端
                Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName, ticString));
                //跳转到登录前页面
                return Redirect(HttpUtility.UrlDecode( Request.QueryString["ReturnUrl"]));
            }
            return View();
        }
退出.
通过 new FormsAuthenticationTicket(model.UserName, false, 时长); 设置.AXPXAUTH过期时长. 但是如果newHttpCookie(FormsAuthentication.FormsCookieName, ticString) 这个cookie对象没有设置过期时间, 那么上面设置的时长再长, cookie的生命周期还是浏览器的生命周期.

public ActionResult Logout() {
            FormsAuthentication.SignOut();
            return Redirect(FormsAuthentication.LoginUrl);
        }
