我想从 Internet Explorer 获取 cookie。所以我遵循网络上的代码。我登录到一个网站，比如 bodis.com，然后我尝试读取 cookie

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总是0。我知道有cookie。我输入 sURL="http://google.com" 以确保每个人都明白我想要 google.com cookie。我已经登录到 google.com 并且确实有 cookie。

我尝试了很多其他网站。http://bodis.com http://www.bodis.com等。没有工作。
