FormsAuthenticationTicket没有存储UserData

Question

我对.NET比较陌生，正在尝试了解FormsAuthentication。我已经看过几个不同的教程，每次我都遇到同样的问题。由于某些原因，UserData没有存储在票证中。当我在Global.aspx.cs中的票证上设置分隔符时，UserName在那里，但UserData是一个空字符串，并且当它被指定为1时，版本被设置为2。另一件奇怪的事情是，当web.config指定只有管理员可以访问我的Admin_Content文件夹中的页面时，每个经过身份验证的用户都可以访问。

Login.aspx

UserFull user = ManageUsers.login(loginTemplate.UserName, loginTemplate.Password);
if (user != null)
{
    string[] roles = { user.role };

    FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(
        1,
        userName,
        DateTime.Now,
        DateTime.Now.AddDays(30),
        true,
        roles[0],
        FormsAuthentication.FormsCookiePath
    );

    string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
    FormsAuthentication.SetAuthCookie(encryptedTicket, true);

    Response.Redirect("Admin_Content/Admin.aspx");
 }

Global.aspx.cs Application_AuthenticateRequest

if (HttpContext.Current.User != null)
{
    if (HttpContext.Current.User.Identity.IsAuthenticated)
    {
        if (HttpContext.Current.User.Identity is FormsIdentity)
        {
            FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity;
            FormsAuthenticationTicket ticket = (id.Ticket);
            if (!string.IsNullOrEmpty(ticket.UserData))
            {
                string userData = ticket.UserData;
                string[] roles = userData.Split(',');
                HttpContext.Current.User = new System.Security.Principal.GenericPrincipal(id, roles);
            }
        }
    }
}

主web.config

<configuration>
<system.web>
  <compilation debug="true" targetFramework="4.0" />
  <roleManager enabled="true"></roleManager>
  <authentication mode="Forms">
    <forms name="AOTMP_Demo" loginUrl="Login.aspx"
    protection="All" path="/" cookieless="UseCookies"/>
  </authentication>
  <authorization>
    <allow users="*"/>
  </authorization>
</system.web>
<configuration>

Admin_Content文件夹的web.config

<configuration>  
  <system.web>
    <authorization>
      <allow roles="Administrator"/>
      <deny users="?"/>
    </authorization>
  </system.web>
</configuration>

Answer 1

你不应该这样做...因为它创建了一个新的授权票证。

FormsAuthentication.SetAuthCookie();

相反，显式设置cookie

var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
cookie.Expires = authTicket.Expiration;
Request.Cookies.Add(cookie);

然后它将在global.asax中可用

var userData = ((FormsIdentity)HttpContext.Current.User.Identity).Ticket.UserData;

Answer 2

试着改变

string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
FormsAuthentication.SetAuthCookie(encryptedTicket, true);

至

HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(authTicket));
Response.Cookies.Add(cookie);

我相信FormsAuthentication.SetAuthCookie已经在内部调用了FormsAuthentication.Encrypt，所以您可能会得到一个格式错误的cookie。
