为什么我没有得到饼干？

Question

我想从Internet Explorer获取cookie。所以我按照网络上的代码。我登录了一个网站，比如说bodis.com，然后我试着读取cookies

Private Declare Function InternetGetCookieEx Lib "wininet.dll" Alias "InternetGetCookieExA" (url As String, cookieName As String, cookieData As System.Text.StringBuilder, ByRef size As Integer, dwFlags As Int32, lpReserved As IntPtr) As Boolean
Private Const InternetCookieHttponly As Int32 = &H2000

Public Function GetUriCookieContainer1(uri As Uri) As System.Net.CookieContainer
    Dim cookies As System.Net.CookieContainer = Nothing
    ' Determine the size of the cookie
    Dim datasize As Integer = 8192 * 16
    Dim cookieData As New System.Text.StringBuilder(datasize)
    Dim sURL = uri.ToString
    sURL = "http://google.com" ' for simplicity sake
    If Not InternetGetCookieEx(sURL, Nothing, cookieData, datasize, InternetCookieHttponly, IntPtr.Zero) Then
        If datasize < 0 Then 'always return 0 even though I am sure there is cookies
            Return Nothing
        End If

...

为什么datasize始终为0.我知道有cookie。我把sURL =“http://google.com”放在一起，以确保每个人都明白我想要google.com cookies。我已经登录google.com，确实有cookies。

我尝试了很多其他网站。 http://bodis.com http://www.bodis.com等等。没有用。
