使用子文件夹名称中的空格下载FTP文件 [英] FTP file download with spaces in sub-folder name

问题描述

我在从ftp站点的子目录下载zip文件时遇到问题。

它适用于任何其他文件类型，即使子目录有空格。

如果子目录没有空格，则zip文件也能正常工作。



异常是远程服务器返回错误：（550）文件不可用（例如，找不到文件，没有访问权限）。



Net.FtpWebResponse.StatusDescription =550访问被拒绝。



非常感谢



我的尝试：

I'm having a problem downloading zip files from a sub-dir of an ftp site.
It works with any other file type even if the sub-dir has spaces.
If the sub-dir has no spaces the zip file works fine too.

The Exception is "The remote server returned an error: (550) File unavailable (e.g., file not found, no access)."

Net.FtpWebResponse.StatusDescription = "550 Access is denied."

Many Thanks

What I have tried:

Public Shared Sub TempDownload()
    Try

        Dim ftpRoot As String = "ftp://10.0.0.99/"
        Dim ftpUser As String = "FtpUserName"
        Dim ftpPass As String = "FtpPassword"

        Dim strMainFolder As String = "\\DOMAIN\FOLDER1"
        Dim myFolder As String = "DEVELOPMENT HOME 948"
        Dim myFile As String = "MyZipFileName.zip"


        Dim reqFTP As Net.FtpWebRequest

        Dim outputStream As New IO.FileStream(IO.Path.Combine(IO.Path.Combine(strMainFolder, myFolder), myFile), IO.FileMode.Create)

        reqFTP = Net.FtpWebRequest.Create(New Uri(ftpRoot & myFolder & "/" & myFile))

        reqFTP.Method = Net.WebRequestMethods.Ftp.DownloadFile
        reqFTP.UseBinary = True
        reqFTP.Credentials = New Net.NetworkCredential(ftpUser, ftpPass)
        reqFTP.UsePassive = False

'=====
'### The exception occurs here
        Dim response As Net.FtpWebResponse = DirectCast(reqFTP.GetResponse(), Net.FtpWebResponse) 
'=====

        Dim ftpStream As IO.Stream = response.GetResponseStream()
        Dim cl As Long = response.ContentLength
        Dim bufferSize As Integer = 2048
        Dim readCount As Integer
        Dim buffer As Byte() = New Byte(bufferSize - 1) {}

        readCount = ftpStream.Read(buffer, 0, bufferSize)
        While readCount > 0
            outputStream.Write(buffer, 0, readCount)
            readCount = ftpStream.Read(buffer, 0, bufferSize)
        End While

        ftpStream.Close()
        outputStream.Close()
        response.Close()

    Catch ex As Net.WebException
        MessageBox.Show(DirectCast(ex.Response, Net.FtpWebResponse).StatusDescription)

    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try

End Sub

推荐答案

这是从服务器发送的响应：

This is the response send from the server:

Net.FtpWebResponse.StatusDescription = "550 Access is denied."

很明显。您无权访问该文件或目录。



如果您可以直接访问服务器，请检查其中的权限。如果没有，请使用可以显示文件权限的FTP客户端（例如FileZilla）。

It is pretty clear. You don't have the rights to access the file or directory.

If you have direct access to the server, check the permissions there. If not, use a FTP client that can show file permissions (e.g. FileZilla).
