FTP Sync Upload Tree w/ Must-Match Filename Constraints

See more FTP Examples

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

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

Swift

func chilkatTest() {
    var success: Bool = false

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

    let ftp = CkoFtp2()!

    ftp.hostname = "ftp.something.com"
    ftp.username = "my_login"
    ftp.password = "my_password"

    // Connect and login to the FTP server.
    success = ftp.connect()
    if success != true {
        print("\(ftp.lastErrorText!)")
        return
    }

    // Set the current remote directory to the root of
    // the tree to receive the uploaded files.
    success = ftp.changeRemoteDir(relativeDirPath: "/subDir1")
    if success != true {
        print("\(ftp.lastErrorText!)")
        return
    }

    // Possible synchronization modes are:
    // mode=0: Upload all files
    // mode=1: Upload all files that do not exist on the FTP server.
    // mode=2: Upload newer or non-existant files.
    // mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.
    // mode=4: transfer missing files or files with size differences.
    // mode=5: same as mode 4, but also newer files. 

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

    // Imagine our local 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/

    ftp.syncMustMatch = "*.eml; *.gif"
    var mode: Int = 0
    success = ftp.syncRemoteTree(localRoot: "c:/temp/subDir1", mode: mode)
    if success != true {
        print("\(ftp.lastErrorText!)")
        return
    }

    success = ftp.disconnect()

    // Show the files downloaded.
    let st = CkoStringTable()!
    ftp.getSyncedFiles(strTable: st)

    var numFiles: Int = st.count.intValue
    var i: Int = 0
    var remoteFilename: String?
    while i < numFiles {
        print("\(st.string(at: i)!)")
        i = i + 1
    }

    // Output showing the files uploaded:

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