使用不同的扩展名将文件上传到 SFTP 服务器

Question

我在 Stack Overflow 上浏览了很多帖子，但没有找到我需要的东西。

I have a file suppose temp.csv

我想将此文件上传到工作正常的 SFTP 服务器。

I need to save this file with different extension like temp.csv.ready

能否就此提出一些建议。

这是我试过的代码，运行良好。但我无法更改文件扩展名。

SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.Sftp,
    HostName = System.Configuration.ConfigurationManager.AppSettings["puthost"].ToString(),
    UserName = System.Configuration.ConfigurationManager.AppSettings["putusername"].ToString(),
    Password = System.Configuration.ConfigurationManager.AppSettings["putpassword"].ToString(),
    PortNumber = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["putport"].ToString()),
    SshHostKeyFingerprint = ... //followed by your 16 bit key 
};
using (Session session = new Session())
{
    session.SessionLogPath = "log.txt";
    session.Open(sessionOptions); //Attempts to connect to your sFtp site
    //Get Ftp File
    TransferOptions transferOptions = new TransferOptions();
    transferOptions.TransferMode = TransferMode.Binary; //The Transfer Mode - 
    //<em style="font-size: 9pt;">Automatic, Binary, or Ascii  
    transferOptions.FilePermissions = null; //Permissions applied to remote files; 
    //null for default permissions.  Can set user, 
    //Group, or other Read/Write/Execute permissions. 
    transferOptions.PreserveTimestamp = false; //Set last write time of 
    //destination file to that of source file - basically change the timestamp 
    //to match destination and source files.   
    transferOptions.ResumeSupport.State = TransferResumeSupportState.Off;
    WinSCP.TransferOperationResult transferResult;
    //the parameter list is: local Path, Remote Path, Delete source file?, transfer Options  
    transferResult = session.PutFiles(@System.Configuration.ConfigurationManager.AppSettings["sendfilesource"].ToString(), System.Configuration.ConfigurationManager.AppSettings["sendfiletarget"].ToString(), false, transferOptions);
}

Answer 1

Session.PutFiles method 的 remotePath 参数是：

Full path to upload the file to.

因此，您需要做的就是指定完整路径，例如：

/remote/path/temp.csv.ready

Answer 2

如果你愿意使用一个库，你可能想使用一个3rd library like componenentpro sftp library。您可以使用 client.UploadFile(@"xxx\temp.csv", "/temp.new.csv") 来完成这项工作。该行代码摘自以下代码示例：

// Create a new class instance.
Sftp client = new Sftp();

// Connect to the SFTP server.
client.Connect("localhost");

// Authenticate.
client.Authenticate("test", "test");

// ... 

// Upload local file 'c:\test.dat' to '/test.dat'.
client.UploadFile(@"xxx\temp.csv", "/temp.new.csv");

// ... 

// Disconnect.
client.Disconnect();
