vb.net - 在VB中通过WebBrowser发送Cookie

Question

所以我已经发送了近两个小时来寻找答案，但没有任何效果。我需要通过我的 webbrowser 对象发送一些 cookie，但由于某种原因，我的 PHP 文件没有读取这些 cookie:

<?php die('Your username is '.$_COOKIE['user']); ?>

和我的 VB 代码来发送 cookie:

For i = 0 To 4
uploadBoxes(i).Navigate("about:blank")
uploadBoxes(i).Document.Cookie = "user=" & username.Text
uploadBoxes(i).Navigate("http://*****/uploader/app.php")
Next i

同样，任何帮助将不胜感激，是的，我确实需要通过 webbrowser 对象发送它。我也浏览过 MSDN 数据库，即使这样也没有说明这个问题。

所以我采用了 InternetSetCookie 方法并想出了这段用于制作 cookie 的代码:

Imports System.Runtime.InteropServices

   ' No more data is available.
    Const ERROR_NO_MORE_ITEMS = 259

    ' The data area passed to a system call is too small.
    Const ERROR_INSUFFICIENT_BUFFER = 122

    Private Declare Function InternetSetCookie Lib "wininet.dll" _
     Alias "InternetSetCookieA" _
     (ByVal lpszUrlName As String, _
     ByVal lpszCookieName As String, _
     ByVal lpszCookieData As String) As Boolean

Private sub something()
              Dim bRet As Boolean
                bRet = InternetSetCookie("http://*****/uploader/app.php", _
                 "user", "admin")
                If bRet = False Then
                    MsgBox("Failed")
                End If
                uploadBoxes(i).Navigate("http:/*****/uploader/app.php")
End sub

  <DllImport("wininet.dll", CharSet:=CharSet.Auto, SetLastError:=True)> _
      Public Shared Function InternetSetCookie(lpszUrl As String, _
      lpszCookieName As String, lpszCookieData As String) As Boolean
     End Function

Imports System.Runtime.InteropServices
Sub InternetSetCookiePseudoCode()
'`CookieCollection` was populated using HttpWebRequest/Response calls
Dim i As Integer = 0
InternetSetCookie("https://www.url.com/", Nothing, CookieCollection(i).ToString() & "; expires = Sun, 01-Jul-2014 00:00:00 GMT")
'repeat for however many cookies you've got

browser.Navigate("https://www.url.com/", True)
End Sub
