SFTP Upload - Synchronize Directory Tree

See more SFTP Examples

Demonstrates how to upload files to synchronize a local directory tree with a remote directory tree. The SyncTreeUpload method recursively descends a local directory tree and uploads files based on existence, last-mod date/time and/or size differences. 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 (by uploading) the local directory tree rooted at "qa_data/sftpUploadTree"
    // with the remote directory tree rooted at "syncUploadTest"
    // 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? = "syncUploadTest"
    var localDir: String? = "qa_data/sftpUploadTree"

    // Possible modes that can be passed to the SyncTreeUpload method are:
    // mode=0: Upload all files
    // mode=1: Upload all files that do not exist on the server.
    // mode=2: Upload newer or non-existant files.
    // mode=3: Upload only newer files. If a file does not already exist on the 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 use mode 5 to upload missing, newer, or files with size differences.
    var mode: Int = 5
    // This example turns 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.syncTreeUpload(localBaseDir: localDir, remoteBaseDir: remoteDir, mode: mode, bRecurse: recursive)
    if success != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    print("Success.")
