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:
vba
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
