Question

我尝试使用以下VBA代码打开网站：

Dim IE As Object
Dim doc As Object
Dim strURL As String

Set IE = CreateObject("InternetExplorer.Application")

With IE '
    .Visible = True
    .navigate "https://Google.com"

    Do Until .readyState = 4
        DoEvents
    Loop

它适用于“ google”等网站。

但是当我尝试打开公司PLM之类的特定网站“ Agile（https://agileplm.XXXX.com/Agile/default/login-cms.jsp）”时抛出错误 “远程服务器计算机不存在或不可用”

我可以在资源管理器上打开网页，但是从下面一行执行时抛出错误

Do Until .readyState = 4
    DoEvents
Loop

这是出于对站点的任何保护吗？

Answer 1

我对此进行了早期绑定，并创建了对象InternetExplorerMedium而不是InternetExplorer，它似乎可以正常工作。

尝试使用下面的示例代码进行测试可能会帮助您解决问题。

Sub Automate_IE_Load_Page()
'This will load a webpage in IE
    Dim i As Long
    Dim URL As String
    Dim IE As Object
    Dim objElement As Object
    Dim objCollection As Object

    'Create InternetExplorer Object
    Set IE = CreateObject("InternetExplorer.Application")

    'Set IE.Visible = True to make IE visible, or False for IE to run in the background
    IE.Visible = True

    'Define URL
    URL = "https://agileplm.xxxx.com/Agile/default/login-cms.jsp"

    'Navigate to URL
    IE.Navigate URL

    ' Statusbar let's user know website is loading
    Application.StatusBar = URL & " is loading. Please wait..."

    ' Wait while IE loading...
    'IE ReadyState = 4 signifies the webpage has loaded (the first loop is set to avoid inadvertently skipping over the second loop)
    Do While IE.ReadyState = 4: DoEvents: Loop   'Do While
    Do Until IE.ReadyState = 4: DoEvents: Loop   'Do Until

    'Webpage Loaded
    Application.StatusBar = URL & " Loaded"

    'Unload IE
    Set IE = Nothing
    Set objElement = Nothing
    Set objCollection = Nothing

End Sub

问题是 Internet Explorer 与 VBA 断开连接（在我的情况下是一些内部安全设置）。解决方案是将 Internet Explorer 重新连接到 VBA：

在 IE 不再响应行之后包含此代码，现有的 Internet Explorer 窗口将被分配给 = IEObject1

    Dim shellWins As SHDocVw.ShellWindows
    Dim explorer As SHDocVw.InternetExplorer
    
    Set shellWins = New SHDocVw.ShellWindows
    
    For Each explorer In shellWins
        If explorer.Name = "Internet Explorer" Then
            Set IEObject1 = explorer
            Debug.Print explorer.LocationURL
            Debug.Print explorer.LocationName
        End If
    Next
    
    Set shellWins = Nothing
    Set explorer = Nothing

如果您打开了多个 IE 窗口，则此代码会选择最后一个。如果您需要多个打开的窗口，您可以使用 URL 或 LocationName 在窗口之间进行选择。
