我使用表单例份验证 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);
如何取回添加的 cookie 和用户详细信息 (authTicket)？
最佳答案
您可以检索 FormsAuthenticationTicket使用类似于以下的代码:
// 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);
}
上面的代码引用了诸如 txtUserName.Text 之类的东西，所以这是一个完整的 .ASPX 页面，您可以将其粘贴到一个空的 ASP.NET 网络表单中以查看它是如何工作的:

<%@ Import Namespace="System.Web.Security" %>

<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,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, 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);
}
}
}
