Question

我发现以下代码使我开始开发一种自动方法来从ftp站点下载文件。但是，它每次都失败，没有任何我可以解决的错误。

我在excel vba中有一个新手，所以可以得到一些帮助。

我尝试过在线搜索，但在此处出现堆栈溢出的情况，但我自己无法解决

'Assign Host URL, Source and Destination File path
Dim HostURL, fileSource, FileDestination As String
HostURL = ThisWorkbook.Sheets(1).Cells(1, 1)
fileSource = ThisWorkbook.Sheets(1).Cells(1, 2)
FileDestination = ThisWorkbook.Sheets(1).Cells(2, 2)
FtpDownload fileSource, FileDestination, HostURL, 21, "Username", "Password"

End Sub

Answer 1

好的，以上代码可以正常工作。我相信问题可能出在您的参考单元内...

HostURL = ThisWorkbook.Sheets(1).Cells(1, 1)
fileSource = ThisWorkbook.Sheets(1).Cells(1, 2)
FileDestination = ThisWorkbook.Sheets(1).Cells(2, 2)

当我把它弄乱时，我发现我必须有这种格式...

HostURL = "192.168.168.2" 'Or your FQDN
fileSource = "/This/Is/The/Path/To/Your/File.file" ' Make sure that this matches your file path
FileDestination = "C:\This\Is\The\Complete\Path\On\Your\Machine.File"

当然，请确保您填充了宏的用户名和密码部分...

FtpDownload fileSource, FileDestination, HostURL, 21, "YOUR_USERNAME_HERE", "YOUR_PASSWORD_HERE"

我现在已经尝试了一切。所以我使用上面的路径。虽然我手动下载文件，但该网址有效。 [ftp://username:password@ftp.datacentre.com/country_forecast/CWG_ecop_19021012_United-Kingdom.csv]
