我如何og:image从资源中获取VBA excel 2007

例如，这个网址：

Answer 1

使用更新版本的 Excel，您可以尝试以下操作：

Sub GetImageFromHead()

    Dim MyUrl As String
    MyUrl = "https://www.bbc.com/reel/video/p08jgfdg/the-truth-about-christopher-columbus"

    'Required library reference: Microsoft XML v6.0
    Dim HttpRequest As MSXML2.XMLHTTP60
    Set HttpRequest = New MSXML2.XMLHTTP60
    HttpRequest.Open "GET", MyUrl, False
    HttpRequest.Send
    
    Dim HtmlDoc As Object
    Set HtmlDoc = CreateObject("htmlfile")
    HtmlDoc.Write HttpRequest.responseText

    'This next line makes sure that the JavaScript on the page gets processed before continuing execution of the code.
    DoEvents 

    'Required library reference: Microsoft HTML Object
    Dim MetaCollection As MSHTML.IHTMLElementCollection
    Set MetaCollection = HtmlDoc.getElementsByTagName("meta")
    
    Dim HtmlElement As MSHTML.IHTMLElement
    For Each HtmlElement In MetaCollection
        If HtmlElement.getAttribute("property") = "og:image" Then
            ActiveSheet.Pictures.Insert (HtmlElement.getAttribute("content"))
        End If
    Next

End Sub

但是由于您的问题是针对 Excel 2007，您必须改为这样定义HttpRequest：

    'Required library reference: Microsoft XML v3.0 or v5.0
    Dim HttpRequest As MSXML2.XMLHTTP
    Set HttpRequest = New MSXML2.XMLHTTP

如果您想要一个只将 URL 作为字符串返回的函数，您可以轻松编辑 Sub 过程，使其成为一个将 MyUrl 作为参数并返回字符串而不是使用它在 Activesheet 中插入图像的函数（像这样例如）。
