vba如何读取和存储LTPA？

Question

我正在尝试使用WinHTTP或xmlHTTP从Excel表单开始到我们的Intranet建立“静默”连接。

我刚刚编写了打开IE，登录，传递数据，编译表单并获取所需信息的代码。现在，我想不打开IE会话就做同样的事情。

我已经写了一些代码，可以达到登录并“导航”到下一页的目的，但是我无法继续。我认为LTPA令牌有问题。我之前在论坛上问过一个更通用的帖子。

这是我的代码

' Takes a string of the form "JSESSIONID=40DD2DFCAF24A2D64544F55194FCE04E;path=/pamsservices;HttpOnly"
' and returns only the portion "JSESSIONID=40DD2DFCAF24A2D64544F55194FCE04E"
Public Function GetJsessionIdCookie(setCookieStr As String) As String
    'JSESSIONID=40DD2DFCAF24A2D64544F55194FCE04E;path=/pamsservices;HttpOnly

    Dim jsessionidCookie As String

    Dim words() As String
    Dim word As Variant

    words = Split(setCookieStr, ";")
    For Each word In words
        If InStr(1, word, "JSESSIONID") > 0 Then
            jsessionidCookie = word
        End If
    Next word

    GetJsessionIdCookie = jsessionidCookie
End Function

Public Sub Login()
    Dim JUserid, userid As String
    Dim JPassword, password As String

    userid = "xxxxxx"
    password = "yyyyyyy"
    JUserid = "j_username=" & userid
    JPassword = "j_password=" & password

    Dim postReq, getReq, cookies
    Dim p0 As Integer, p1 As Integer, temp As String
    Dim result As String, respHead As String
    Dim http As Object

    Set http = CreateObject("WinHttp.WinHttpRequest.5.1") 'initialize  other CreateObject("MSXML2.serverXMLHTTP.6.0") or 'CreateObject("MSXML2.serverXMLHTTP.6.0")

我为我的英语不好和我犯的“严重错误”表示歉意。
