AWS Transfer for SFTP (Amazon S3)

See more SFTP Examples

Once you've setup your AWS Transfer for SFTP in the AWS Console, interacting with it is no different than any other SSH/SFTP server. AWS will provide a private key in PEM format. It is used for authentication (instead of a password). Visual FoxPro

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

loSftp = CreateObject('Chilkat.SFtp')

* Connect to the AWS SFTP server.
* Change the domain to your value.
lcDomain = "s-123456df999999fab.server.transfer.eu-west-2.amazonaws.com"
lnPort = 22
lnSuccess = loSftp.Connect(lcDomain,lnPort)
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Load your AWS SFTP private key PEM file..
loSshKey = CreateObject('Chilkat.SshKey')
lcKeyText = loSshKey.LoadText("qa_data/pem/s3_sftp_privateKey.pem")
IF (loSshKey.LastMethodSuccess <> 1) THEN
    ? loSshKey.LastErrorText
    RELEASE loSftp
    RELEASE loSshKey
    CANCEL
ENDIF

lnSuccess = loSshKey.FromOpenSshPrivateKey(lcKeyText)
IF (lnSuccess = 0) THEN
    ? loSshKey.LastErrorText
    RELEASE loSftp
    RELEASE loSshKey
    CANCEL
ENDIF

* Authenticate with the SSH server using the private key.
lnSuccess = loSftp.AuthenticatePk("myUsername",loSshKey)
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    RELEASE loSshKey
    CANCEL
ENDIF

* After authenticating, the SFTP subsystem must be initialized:
lnSuccess = loSftp.InitializeSftp()
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    RELEASE loSshKey
    CANCEL
ENDIF

* Upload from the local file to the SSH server.
* Important -- the remote filepath is the 1st argument,
* the local filepath is the 2nd argument;
lcRemoteFilePath = "hamlet.xml"
lcLocalFilePath = "c:/temp/hamlet.xml"

lnSuccess = loSftp.UploadFileByName(lcRemoteFilePath,lcLocalFilePath)
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    RELEASE loSshKey
    CANCEL
ENDIF

? "Success."

RELEASE loSftp
