问题:

在微软宣布停止对IE的支持后,许多使用VBA中Web Browser的用户遇到了困境,因为Web Browser使用的IE内核。然而微软并没有给出支持Edge的新版Web Browser,网上许多第三方的库也不够完善。

解决方案:

经过调研,libEdge可以较好的和VBA集成,实现在Excel中打开Browser,甚至能够通过执行js代码,获取web页面的信息。

注意:
项目需要WebView2Loader.dll和LibEdge.dll两个库,区分x86和x64版本。

示例代码:

Public Function GetEncodedCookieFromWebBrowser(serverIP As String) As String
    Dim url As String
    Dim encodedCookie As String
    Dim isValidIPFormat As Boolean
    Dim jsResult As String
    Dim path As String

    encodedCookie = ""
    url = "https://" + serverIP + "/proj/demo/" + Guid()
    isValidIPFormat = IsValidIP(serverIP)
    path = Application.ActiveWorkbook.path & "\"
    ChDir path

    If isValidIPFormat = False Then
        If VBA_StartEdge() <> 0 Then Exit Function

        VBA_Navigate url

        ' Wait for the page to fully load
        Do While Not PageLoaded
            Sleep 500 ' Sleep for 500 milliseconds to allow user interaction
            DoEvents
        Loop

        ' Wait until the cookie contains 'token%22'
        Do Until InStr(jsResult, "token%22") > 0
            If VBA_RunJavascript("document.cookie", jsResult) <> 0 Then
                VBA_StopEdge True
                Exit Function
            End If
            Sleep 500 ' Sleep for 500 milliseconds to allow user interaction
            DoEvents
        Loop
        encodedCookie = jsResult
        VBA_StopEdge True
    End If
    GetEncodedCookieFromWebBrowser = encodedCookie
End Function
