我发现下面的代码我开始了与开发自动化的方式来从FTP站点下载文件。然而，它没有失败，我可以解决任何错误每次。

我在Excel VBA中一个新手，所以一些帮助，将不胜感激。

我曾尝试在网上，并在这里寻找在堆栈溢出，但我could'nt算出这个对我自己

FtpDownload fileSource, FileDestination, HostURL, 21, "Username", "Password"

Answer 1

好了，上面的代码工作没有任何问题。我相信问题可能是你的参考单元内...

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

当我与这混乱的时候，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，请确保您填写的宏的用户名和密码部分...

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

Answer 2

Dim HostURL, fileSource, FileDestination As String
    HostURL = "ftp.datacentre.com"
    fileSource = "/country_forecast/CWG_ecop_19021012_United-Kingdom.csv"
    FileDestination = "C:\Development\Test1\newFile.txt"

FtpDownload fileSource, FileDestination, HostURL, 21, "username", "password"

我现在已经尝试了一切。所以我用上面的路径。该网址的作品，虽然我我手动下载该文件。 [ftp://username:[email protected]/country_forecast/CWG_ecop_19021012_United-Kingdom.csv]
