有人能给我一个例子（或指点一下方向），如何在ASP.NET Membership cookie中存储自定义数据吗？
我需要添加一些自定义属性，例如UserID和URLSlug到cookie，并且能够以与检索用户名相同的方式检索信息。

当我在
Dim SerializedUser As String = SerializeUser(userData)处设置断点时，userData的值是正确的。它拥有我期望的所有属性。我现在遇到的问题是，当我到达
Dim userdata As String = authTicket.UserData（断点）时，值为""。我很想弄清楚我做错了什么。这是代码。
Imports System
Imports System.Web
Imports System.Web.Security
Namespace Utilities.Authentication
Public NotInheritable Class CustomAuthentication
Private Sub New()
End Sub
Public Shared Function CreateAuthCookie(ByVal userName As String, ByVal userData As Domain.Models.UserSessionModel, ByVal persistent As Boolean) As HttpCookie
Dim issued As DateTime = DateTime.Now
''# formsAuth does not expose timeout!? have to hack around the
''# spoiled parts and keep moving..
Dim fooCookie As HttpCookie = FormsAuthentication.GetAuthCookie("foo", True)
Dim formsTimeout As Integer = Convert.ToInt32((fooCookie.Expires - DateTime.Now).TotalMinutes)
Dim expiration As DateTime = DateTime.Now.AddMinutes(formsTimeout)
Dim cookiePath As String = FormsAuthentication.FormsCookiePath
Dim SerializedUser As String = SerializeUser(userData)
Dim ticket = New FormsAuthenticationTicket(0, userName, issued, expiration, True, SerializedUser, cookiePath)
Return CreateAuthCookie(ticket, expiration, persistent)
End Function
Public Shared Function CreateAuthCookie(ByVal ticket As FormsAuthenticationTicket, ByVal expiration As DateTime, ByVal persistent As Boolean) As HttpCookie
Dim creamyFilling As String = FormsAuthentication.Encrypt(ticket)
Dim cookie = New HttpCookie(FormsAuthentication.FormsCookieName, creamyFilling) With { _
.Domain = FormsAuthentication.CookieDomain, _
.Path = FormsAuthentication.FormsCookiePath _
}
If persistent Then
cookie.Expires = expiration
End If
Return cookie
End Function
Public Shared Function RetrieveAuthUser() As Domain.Models.UserSessionModel
Dim cookieName As String = FormsAuthentication.FormsCookieName
Dim authCookie As HttpCookie = HttpContext.Current.Request.Cookies(cookieName)
Dim authTicket As FormsAuthenticationTicket = FormsAuthentication.Decrypt(authCookie.Value)
Dim userdata As String = authTicket.UserData
Dim usersessionmodel As New Domain.Models.UserSessionModel
usersessionmodel = DeserializeUser(userdata)
Return usersessionmodel
End Function
Private Shared Function SerializeUser(ByVal usersessionmodel As Domain.Models.UserSessionModel) As String
Dim bf As New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim mem As New IO.MemoryStream
bf.Serialize(mem, usersessionmodel)
Return Convert.ToBase64String(mem.ToArray())
End Function
Private Shared Function DeserializeUser(ByVal serializedusersessionmodel As String) As Domain.Models.UserSessionModel
Dim bf As New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim mem As New IO.MemoryStream(Convert.FromBase64String(serializedusersessionmodel))
Return DirectCast(bf.Deserialize(mem), Domain.Models.UserSessionModel)
End Function
End Class
End Namespace
这里是我创造所有魔法的地方。这种方法在“BaseController”类中，继承了System.Web.Mvc.Controller。
Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker
If User.Identity.IsAuthenticated Then ''# this if statement will eventually also check to make sure that the cookie actually exists.
Dim sessionuser As Domain.Models.UserSessionModel = New Domain.Models.UserSessionModel(OpenIdService.GetOpenId(HttpContext.User.Identity.Name).User)
HttpContext.Response.Cookies.Add(UrbanNow.Core.Utilities.Authentication.CustomAuthentication.CreateAuthCookie(HttpContext.User.Identity.Name, sessionuser, True))
End If
End Function
以下是我尝试检索信息的方法。
Dim user As Domain.Models.UserSessionModel = CustomAuthentication.RetrieveAuthUser
Response.Cookies.Add没有起作用，因为它发生在错误的位置。Cookie 已经在身份验证步骤中创建了。我必须删除在 Auth 步骤中创建 Cookie 的代码，并将其替换为 CreateActionInvoker 方法中的代码。 - Chase Florell
