Question

所以我差不多花了两个小时寻找答案，但没有任何工作。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cookie：

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

我的VB代码发送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，任何帮助都会受到赞赏，是的，我需要通过webbrowser对象发送它。我也浏览过MSDN数据库，甚至没有对这个问题有所了解。

所以我采用了InternetSetCookie方法并提出了制作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

http://pinvoke.net/default.aspx/wininet.InternetSetCookie

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

Answer 2

以下是我用来为VB.Net Webbrowser Control手动设置cookie的旧版本：

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

[...]

Dim CookieVal As String = "asdfghjkl12345"
Dim CookieNamestr As String = "sessionid"
Try
    Dim Result As Long = InternetSetCookie("https://www.url.com/", CookieNamestr, CookieVal )
Catch ex As Exception
End Try

在VB中通过WebBrowser发送Cookie
