Question

我在cookie中存储了一些UserData。它在铬和mozilla中工作正常。但是在IE中它无法获取cookie。我正在使用IE版本10.请帮帮我吗？

在登录表单中：

        Dim Mydtt As String = "my custom data "
        Dim authTicket = New FormsAuthenticationTicket(2, usrid, Date.Now, Date.Now.AddDays(7), True, Mydtt, "/")

        Dim cookie As New HttpCookie("usrlg", FormsAuthentication.Encrypt(authTicket))
        Response.Cookies.Set(cookie)
        Response.Redirect("~/phed/reports")

在会话开始时：

        Dim LastLoginCookie As HttpCookie
        LastLoginCookie = HttpContext.Current.Request.Cookies.Get("usrlg") ' Return Nothing in IE '
        Dim LastLgTicket As FormsAuthenticationTicket = FormsAuthentication.Decrypt(LastLoginCookie.Value)
        Dim Mydtt As String = LastLgTicket.UserData

Answer 1

您可能希望在解密之前检查空值。

Dim LastLoginCookie = HttpContext.Current.Request.Cookies("usrlg")

If LastLoginCookie IsNot Nothing Then
   Dim LastLgTicket As FormsAuthenticationTicket = 
      FormsAuthentication.Decrypt(LastLoginCookie.Value)
   Dim Mydtt As String = LastLgTicket.UserData
End If

Answer 2

我记得cookie.Secure必须正确设置，例如HTTP为false，HTTPS为true。您可以使用Request对象自动检测协议：

cookie.Secure = Request.IsSecureConnection;
Response.Cookies.Set(cookie);

希望这有帮助。
