(Go) SFTP Synchronize Directory Tree - Download

Demonstrates how to download files to synchronize a local directory tree with a remote directory tree. The SyncTreeDownload method recursively descends the remote directory tree and downloads files based on existence, last-mod date/time and/or size differences.

    // This example requires the Chilkat SFTP API to have been previously unlocked.
    // See Unlock Chilkat SFTP for sample code.

    sftp := chilkat.NewSFtp()

    success := sftp.Connect("my-ssh-server.com",22)
    if success == true {
        success = sftp.AuthenticatePw("mySshLogin","mySshPassword")
    }

    if success == true {
        success = sftp.InitializeSftp()
    }

    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()
        return
    }

    // Synchronize the remote directory tree rooted at "syncDownloadTest/xml"
    // with the local directory tree rooted at "qa_output"
    // Both directories are relative paths.  The remote directory
    // is relative to the HOME directory of the SSH user account.
    // The local directory is relative to the current working directory of the process.
    // It is also possible to use absolute paths.

    remoteDir := "syncDownloadTest/xml"
    localDir := "qa_output"

    // Possible modes that can be passed to the SyncTreeDownload method are:
    // mode=0: Download all files
    // mode=1: Download all files that do not exist on the local filesystem.
    // mode=2: Download newer or non-existant files.
    // mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
    // mode=5: Download only missing files or files with size differences.
    // mode=6: Same as mode 5, but also download newer files.
    // mode=99: Do not download files, but instead delete remote files that do not exist locally.

    // This example will use mode 6 to download missing, newer, or files with size differences.
    mode := 6
    // This example will turn on recursion to synchronize the entire tree. 
    // Recursion can be turned off to synchronize the files of a single directory.
    recursive := true
    success = sftp.SyncTreeDownload(remoteDir,localDir,mode,recursive)
    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()
        return
    }
