问题描述
我正在使用以下代码段从网站下载PDF文件。
I am using the below code snippet to download a PDF file from a website.
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
<html>
<head>

我也尝试了以下方法
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？
when i open the url given in the above code in browser,i can see pdf file getting opened automatically.How do i download the same pdf file opened in my browser using code?
有人可以帮我解决这个问题吗？
Can some one help me to resolve the issue.
推荐答案
我可以想到几种解决方法。如果要循环浏览一堆链接并下载所有文件，可以在Excel中设置库存清单，如下图所示。
I can think of a couple ways to do this. If you want to loop through a bunch of links, and download all files, you can setup an inventory list in Excel, like you see in the image below.
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。
Now, if you just want to download one single file, run the script below.
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
