SSIS 任务 - FTP 连接

Question

全部，

SSIS - 尝试使用可视化基本编程语言中的脚本任务建立 ftp 连接以将文件上传到 ftp 服务器，我遇到了运行问题。我在搜索中没有找到类似的东西，所以非常感谢你的帮助。

[连接管理器“FTP”]错误：请求的 FTP 操作发生错误。详细错误描述：220
控制通道需要 550 SSL/TLS

代码：

Public Sub Main()

    '
    ' Add your code here
    '

    Try

        Dim cm As ConnectionManager

        cm = Dts.Connections("FTP")

        'Set the properties like username & password
        cm.Properties("ServerName").SetValue(cm, "ftps.example.com")
        cm.Properties("ServerUserName").SetValue(cm, "username")
        cm.Properties("ServerPassword").SetValue(cm, "password")
        cm.Properties("ServerPort").SetValue(cm, "port")
        cm.Properties("Timeout").SetValue(cm, "0") 'The 0 setting will make it not timeout
        cm.Properties("ChunkSize").SetValue(cm, "1000") '1000 kb
        cm.Properties("Retries").SetValue(cm, "1")

        'create the FTP object that sends the files and pass it the connection created above.

        Dim ftp As FtpClientConnection = New FtpClientConnection(cm.AcquireConnection(Nothing))

        'Connects to the ftp server

        ftp.Connect()


        'Build a array of all the file names that is going to be FTP'ed (in this case only one file)

        Dim files(0) As String

        files(0) = "C:\ local path file"

        'ftp the file 

        ftp.SendFiles(files, "/remote path", True, False) ' the True makes it overwrite existing file and False is saying that it is not transferring ASCII

        ftp.Close()

    Catch ex As Exception

        Dts.TaskResult = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure


    End Try

……我终于解决了。我将语言脚本任务更改为 C#（它在 VB 中工作，您只需调整代码）并使用 this 评论中的代码。

注意：如果服务器位于 21 以外的端口上，您必须在远程路径中指定它。谢谢。

   public void Main()
   {
    // TODO: Add your code here
     FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftps.example.com:port/remote/path/file.zip");
    request.Credentials = new NetworkCredential("username", "password");
        request.EnableSsl = true;
        request.Method = WebRequestMethods.Ftp.UploadFile;  

        using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip"))
        using (Stream ftpStream = request.GetRequestStream())
          {
        fileStream.CopyTo(ftpStream);
          }
    }
