(Go) SFTP Sync Download Tree w/ Must-Match Filename Constraints

Demonstrates how synchronize a directory tree in the download direction, but only download files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample 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
    }

    // Possible synchronization modes 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.

    // This example will download all files, but only those files having filenames
    // that match *.gif and *.eml

    // Imagine our remote directory tree has these files and directories:

    // 	accentedLatin1.txt
    // 	accentedUtf8.txt
    // 	alice.key
    // 	anter_cert.pem
    // 	chiliPepper.gif
    // 	helloWorld.pdf
    // 	abc/chiliPepper.gif
    // 	abc/ghk/
    // 	data/chiliPepper.gif
    // 	data/xyz/dkimHtmlBody.txt
    // 	data/xyz/dkimVerifyTest.eml
    // 	data/xyz/emailForCreateDsn.eml
    // 	text/frenchUtf8.txt
    // 	text/helloWorld.txt
    // 	text/PolishEmailBody.txt
    // 	text/something/

    // Indicate that we only want to create auto-create local directories (if needed)
    // for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
    // true, then the corresponding local directory is created for each remote directory
    // traversed regardless of whether files within are downloaded.
    sftp.SetSyncCreateAllLocalDirs(false)

    sftp.SetSyncMustMatch("*.eml; *.gif")

    remoteDir := "syncDownloadTest/someDir"
    localDir := "qa_output"
    mode := 0
    recursive := true
    success = sftp.SyncTreeDownload(remoteDir,localDir,mode,recursive)
    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()
        return
    }

    // The following files were downloaded:

    // chiliPepper.gif
    // abc/chiliPepper.gif
    // data/chiliPepper.gif
    // data/xyz/dkimVerifyTest.eml
    // data/xyz/emailForCreateDsn.eml

    fmt.Println("Success.")

    sftp.DisposeSFtp()
