Question

我使用以下代码段从网站下载PDF文件。

Option Explicit

Private Declare Function URLDownloadToFile Lib "urlmon" Alias   "URLDownloadToFileA" _
   (ByVal pCaller As Long, _
   ByVal szURL As String, _
   ByVal szFileName As String, _
   ByVal dwReserved As Long, _
   ByVal lpfnCB As Long) As Long

Sub Test()
    Dim strPDFLink As String
    Dim strPDFFile As String
    Dim Result As Boolean
    strPDFLink = "myurl?SessionKey=rCpZeX9UP300002D50BA&  docid=*8G0leLEfTTX3oX8QpVUmKqRoTj6zS6bzTWf9%29Dt1hij3ym9hKqucLhtOnWVeCgM0wyGJyjI9RNj3Kv&PageNo=1"
    strPDFFile = "D:\Users\d828737\Desktop\Doc Comparison\Temp\abcd.pdf"
    Result = DownloadFile(strPDFLink, strPDFFile)
End Sub

Function DownloadFile(URL As String, LocalFilename As String) As   Boolean
    Dim lngRetVal As Long
    lngRetVal = URLDownloadToFile(0, URL, LocalFilename, 0, 0)
    If lngRetVal = 0 Then DownloadFile = True
End Function

Below is the response i am getting from browser using code

我也尝试过以下方法

Set WHTTP = CreateObject("WinHTTP.WinHTTPrequest.5.1")
WHTTP.Open "GET", fileUrl, False
WHTTP.Send
FileData = WHTTP.ResponseBody

当我在浏览器中打开上面代码中给出的URL时，我可以看到pdf文件自动打开。如何使用代码下载在浏览器中打开的相同pdf文件？

有人可以帮我解决问题。

我可以想到几种方法来做到这一点。如果您想循环浏览一堆链接并下载所有文件，可以在Excel中设置清单列表，如下图所示。

然后，运行以下宏。

Private Declare Function URLDownloadToFile Lib "urlmon" Alias _
  "URLDownloadToFileA" (ByVal pCaller As Long, ByVal szURL As String, ByVal _
    szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long

Sub DownloadFilefromWeb()
    Dim strSavePath As String
    Dim URL As String, ext As String
    Dim buf, ret As Long
    URL = Worksheets("Sheet1").Range("A2").Value
    buf = Split(URL, ".")
    ext = buf(UBound(buf))
    strSavePath = "C:\Users\rshuell\Desktop\Downloads\" & "DownloadedFile." & ext
    ret = URLDownloadToFile(0, URL, strSavePath, 0, 0)
    If ret = 0 Then
        MsgBox "Download has been succeed!"
    Else
        MsgBox "Error"
    End If
End Sub

现在，如果您只想下载一个文件，请运行以下脚本。

Sub DownloadFileWithVBA()

Dim myURL As String
'Right-click on the link named 'Sample Address File'
'Click 'Copy Link Location'
'Paste the link below
myURL = "http://databases.about.com/library/samples/address.xls"

Dim WinHttpReq As Object
Set WinHttpReq = CreateObject("Microsoft.XMLHTTP")
WinHttpReq.Open "GET", myURL, False
WinHttpReq.Send

myURL = WinHttpReq.ResponseBody
    Set oStream = CreateObject("ADODB.Stream")
    oStream.Open
    oStream.Type = 1
    oStream.Write WinHttpReq.ResponseBody
    oStream.SaveToFile ("C:\Users\Excel\Desktop\address.xls")
    oStream.Close

End Sub
