WinSCP錯誤「沒有這樣的文件」，當上傳文件到服務器

Question

當前我編程上試圖上傳文件到使用WinSCP API的服務器。

但是，每次嘗試執行此操作時都會查看日誌文件，我收到一條錯誤消息，指出遠程文件或其目錄不存在。

代碼：

Dim objftp As New WinSCP.SessionOptions 
objftp.HostName = Server 
objftp.PortNumber = Port 
objftp.Protocol = Protocol.Sftp 
objftp.UserName = User 
objftp.Password = Password 
objftp.PrivateKeyPassphrase = "passPhrase" 
objftp.SshPrivateKeyPath = "\\PathToPrivatekey.ppk" 
objftp.GiveUpSecurityAndAcceptAnySshHostKey = True 

Dim session As New Session 

session.Timeout = System.TimeSpan.FromSeconds(30) 
session.SessionLogPath = "C:\Temp\ftpLog\winscp.log" 
session.Open(objFTP) 

Dim transferOptions As New TransferOptions 

transferOptions.TransferMode = TransferMode.Binary 
transferOptions.ResumeSupport.State = TransferResumeSupportState.Off 
Dim transferResult As TransferOperationResult 

strLocalFile = FilePath & FileName 
strRemoteFile = FileName 
transferResult = session.PutFiles(strLocalFile, "/In/", False, transferOptions) 

transferResult.Check() 

session.Close() 

現在我已經使用手動的WinSCP連接到服務器，我可以確認/In/目錄確實存在。我正在使用Windows操作系統來執行此操作。我沒有關於服務器的完整詳細信息，因爲它是我發送信息的第三方。

在我的代碼中是否存在缺少的東西？

編輯：根據要求，這是我的日誌：從編程嘗試它

Answer 1

Documentation將討論遠程文件的完整路徑，而不是包含該文件的目錄。你可以嘗試指定完整路徑：

transferResult = session.PutFiles(strLocalFile, "/In/remote_file.ext", False, transferOptions) 

Answer 2

雖然我不能告訴是肯定的，因爲你沒有提供足夠的信息，我的猜測是，你真正的目標路徑應/Home/user/In/，不只是/In/。

從GUI日誌看來，您的帳戶似乎不是chrooted，因爲主目錄是/Home/user/，而不是/。

. 2016-12-23 10:59:14.386 Listing directory "/Home/user".
