如何使用VBA从Internet Explorer下载文件

Question

我正在尝试从Internet Explorer 11下载excel工作簿，当我点击该链接时，会显示以下弹出消息：

我尝试使用sendkeys“％s”，但它无效。我不能使用代码从互联网上下载文件而不使用IE，因为URL是我公司的内部网站点。

Sub Site()
    Dim IE As Object
    Set IE = CreateObject("InternetExplorer.application")
    With IE
        .Visible = True
        .Navigate "http://asint010/IntegradorProfit/Pages/Relatorios/FluxoSolicitacao.aspx"

        While .Busy Or .ReadyState <> 4
            DoEvents
        Wend

        .document.All("ctl00_ContentPlaceHolder1_btnexportar").Click
        While .Busy Or .ReadyState <> 4
            DoEvents
        Wend

       'here I don't know what to do

    End With
End Sub

我正在使用此代码下载该文件。您需要根据语言设置更改代码。您也可以删除一些不需要的声明功能行。
