是否可以更新FormsAuthentication cookie值？

Question

我必须在登录时设置FormsAuthenticationcookie值(FormsAuthentication.SetAuthCookie(UserDesignation, false)).现在我需要提供指定更改选项.因此,当用户更改其名称时,我需要将FormsAuthenticationcookie值从旧指定更新为新指定.

有可能吗？

如果是的话,我该怎么做？

Answer 1

您可以修改cookie数据,如下所示,但我最好将角色保存在单独的cookie中并使用FormsAuthentication cookie对其进行身份验证

HttpCookie cookie = FormsAuthentication.GetAuthCookie(Username, true);
var ticket = FormsAuthentication.Decrypt(cookie.Value);

var newticket = new FormsAuthenticationTicket(ticket.Version,
                                              ticket.Name,
                                              ticket.IssueDate,
                                              ticket.Expiration,
                                              true, //persistent 
                                              "user data,designation",
                                              ticket.CookiePath);

cookie.Value = FormsAuthentication.Encrypt(newticket);
cookie.Expires = newticket.Expiration.AddHours(2);
HttpContext.Current.Response.Cookies.Set(cookie);
