下载.pdf文件限制？ （Microsoft.XMLHTTP） [英] Download .pdf file limit? (Microsoft.XMLHTTP)
问题描述
在Excel 2013中，我在循环中使用下面的VBA代码，每天从网站下载几百个.pdf文件。从星期五（9/21/18）开始，它一直运行良好多年，代码只下载101个文件，然后停止并给出"指定资源的
下载失败"。错误信息。我关闭Excel并在我离开时再次启动该过程，它再执行101个文件并停止。你知道是什么导致了这个以及为什么它刚刚开始发生吗？感谢
的帮助！
In Excel 2013, I'm using the VBA code below in a loop to download a few hundred .pdf files a day from a website. It's been working fine for years then starting on Friday (9/21/18), the code would only download 101 files and then stop and give the "The download of the specified resource has failed" error message. I close Excel and start the process again where I left off and it does another 101 files and stops. Do you have any idea what is causing this and why It just started happening? Thanks for the help!
Dim myURL As String
myURL ="把你的下载链接放在这里"
Dim myURL As String
myURL = "Put your download link here"
Dim HttpReq As Object
设置HttpReq = CreateObject（" Microsoft.XMLHTTP"）
HttpReq.Open" GET"， myURL，False，"username"，" password"
HttpReq.send
Dim HttpReq As Object
Set HttpReq = CreateObject("Microsoft.XMLHTTP")
HttpReq.Open "GET", myURL, False, "username", "password"
HttpReq.send
myURL = HttpReq.responseBody
如果HttpReq.Status = 200则为
设置oStrm = CreateObject（" ADODB.Stream"）
oStrm.Open
oStrm.Type = 1
oStrm.Write HttpReq.responseBody
oStrm.SaveToFile ThisWorkbook.Path& " \" &安培; " file.csv"，2'1 =不覆盖，2 =覆盖
oStrm.Close
结束如果
myURL = HttpReq.responseBody
If HttpReq.Status = 200 Then
Set oStrm = CreateObject("ADODB.Stream")
oStrm.Open
oStrm.Type = 1
oStrm.Write HttpReq.responseBody
oStrm.SaveToFile ThisWorkbook.Path & "\" & "file.csv", 2 ' 1 = no overwrite, 2 = overwrite
oStrm.Close
End If
推荐答案
您好，
您的代码中没有包含可见错误。
Your code didn't contain visible errors.
但是，您没有处理所有响应代码 - 您只选择"200 Ok"。其他代码可以告诉你服务器上出了什么问题。
However, You didn't handle all response codes - you picking up only "200 Ok". Other codes can tell you what is wrong on the server.
