c# – 访问表单身份验证票证

我使用表单身份验证cookie存储用户详细信息.

FormsAuthenticationTicket authTicket = new  FormsAuthenticationTicket(1,userName,DateTime.Now,DateTime.Now.AddMinutes(Timeout)false};

string encryptedTicket = FormsAuthentication.Encrypt(authTicket);

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

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

如何获取添加的cookie和用户详细信息(authTicket)？

解决方法

您可以使用类似于以下内容的代码检索 FormsAuthenticationTicket：

// Retrieves the cookie that contains your custom FormsAuthenticationTicket.
HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];

// Decrypts the FormsAuthenticationTicket that is held in the cookie's .Value property.
FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);

// The "authTicket" variable now contains your original,custom FormsAuthenticationTicket,// complete with User-specific custom data.  You can then check that the FormsAuthenticationTicket's
// .Name property is for the correct user,and perform the relevant functions with the ticket.
// Here,we simply write the user-specific data to the Http Response stream.
if (authTicket.Name == txtUserName.Text)
{
    Response.Write(authTicket.UserData);
}

上面的代码引用了txtUserName.Text之类的东西,所以这里有一个完整的.ASPX页面,您可以将其粘贴到一个空的ASP.NET webform中以查看它是如何工作的：

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Web.Security" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">


    protected void Page_Load(object sender,EventArgs e)
    {
        double Timeout = 15.00;

        if (!IsPostBack)
        {
            FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1,txtUserName.Text,DateTime.Now.AddMinutes(Timeout),false,"This is my secret user-specific data");

            string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
            HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName,encryptedTicket);
            HttpContext.Current.Response.Cookies.Add(authCookie);
        }
        else
        {
            // Retrieves the cookie that contains your custom FormsAuthenticationTicket.
            HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];

            // Decrypts the FormsAuthenticationTicket that is held in the cookie's .Value property.
            FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);

            // The "authTicket" variable now contains your original,// complete with User-specific custom data.  You can then check that the FormsAuthenticationTicket's
            // .Name property is for the correct user,and perform the relevant functions with the ticket.
            // Here,we simply write the user-specific data to the Http Response stream.
            if (authTicket.Name == txtUserName.Text)
            {
                Response.Write(authTicket.UserData);
            }
        }
    }        
</script>
