SFTP Upload from Local Filesystem

See more SFTP Examples

Demonstrates how to upload a file to an SSH server. There are no limitations on file size, and the file is streamed directly from the local filesystem. Visual FoxPro

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loSftp = CreateObject('Chilkat.SFtp')

* Set some timeouts, in milliseconds:
loSftp.ConnectTimeoutMs = 5000
loSftp.IdleTimeoutMs = 10000

* Connect to the SSH server.  
* The standard SSH port = 22
* The hostname may be a hostname or IP address.
lcHostname = "sftp.example.com"
lnPort = 22
lnSuccess = loSftp.Connect(lcHostname,lnPort)
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Authenticate with the SSH server.  Chilkat SFTP supports
* both password-based authenication as well as public-key
* authentication.  This example uses password authenication.
lnSuccess = loSftp.AuthenticatePw("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* After authenticating, the SFTP subsystem must be initialized:
lnSuccess = loSftp.InitializeSftp()
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Open a file for writing on the SSH server.
* If the file already exists, it is overwritten.
* (Specify "createNew" instead of "createTruncate" to
* prevent overwriting existing files.)
lcHandle = loSftp.OpenFile("hamlet.xml","writeOnly","createTruncate")
IF (loSftp.LastMethodSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Upload from the local file to the SSH server.
lnSuccess = loSftp.UploadFile(lcHandle,"c:/temp/hamlet.xml")
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* -----------------------------------------------------------------------------
* This is important.  You must close the handle on the server.
* Otherwise open handles will accumulate on the server until eventually a limit
* is reached and the server will fail on a call to OpenFile.
* -----------------------------------------------------------------------------

* Close the file.
lnSuccess = loSftp.CloseHandle(lcHandle)
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

? "Success."
