SFTP SyncTreeDownload - Find out what files were downloaded

See more SFTP Examples

Demonstrates how to find out which files were downloaded in a SyncTreeDownload method call. 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 sftp = CkoSFtp()!

    success = sftp.connect(hostname: "my-ssh-server.com", port: 22)
    if success == true {
        success = sftp.authenticatePw(login: "mySshLogin", password: "mySshPassword")
    }

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

    if success != true {
        print("\(sftp.lastErrorText!)")
        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.

    var remoteDir: String? = "syncDownloadTest"
    var localDir: String? = "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.
    var mode: Int = 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.
    var recursive: Bool = true
    success = sftp.syncTreeDownload(remoteRoot: remoteDir, localRoot: localDir, mode: mode, recurse: recursive)
    if success != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    // Examine the list of downloaded files.
    let st = CkoStringTable()!
    sftp.getSyncedFiles(strTab: 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
    }

    // For example:

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