概述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 = FormsAuthentic 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:
