SFTP Upload from Local Filesystem

See more SFTP Examples

Demonstrates how to upload a file to an SSH server. There are no limitations on file size, and the file is streamed directly from the local filesystem. Swift

func chilkatTest() {
    var success: Bool = false

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

    let sftp = CkoSFtp()!

    // Set some timeouts, in milliseconds:
    sftp.connectTimeoutMs = 5000
    sftp.idleTimeoutMs = 10000

    // Connect to the SSH server.  
    // The standard SSH port = 22
    // The hostname may be a hostname or IP address.
    var hostname: String? = "sftp.example.com"
    var port: Int = 22
    success = sftp.connect(hostname: hostname, port: port)
    if success != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    // Authenticate with the SSH server.  Chilkat SFTP supports
    // both password-based authenication as well as public-key
    // authentication.  This example uses password authenication.
    success = sftp.authenticatePw(login: "myLogin", password: "myPassword")
    if success != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    // After authenticating, the SFTP subsystem must be initialized:
    success = sftp.initializeSftp()
    if success != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    // Open a file for writing on the SSH server.
    // If the file already exists, it is overwritten.
    // (Specify "createNew" instead of "createTruncate" to
    // prevent overwriting existing files.)
    var handle: String? = sftp.openFile(filename: "hamlet.xml", access: "writeOnly", createDisp: "createTruncate")
    if sftp.lastMethodSuccess != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    // Upload from the local file to the SSH server.
    success = sftp.uploadFile(sftpHandle: handle, fromFilePath: "c:/temp/hamlet.xml")
    if success != true {
        print("\(sftp.lastErrorText!)")
        return
    }

    // -----------------------------------------------------------------------------
    // This is important.  You must close the handle on the server.
    // Otherwise open handles will accumulate on the server until eventually a limit
    // is reached and the server will fail on a call to OpenFile.
    // -----------------------------------------------------------------------------

    // Close the file.
    success = sftp.closeHandle(sftpHandle: handle)
    if success != true {
        print("\(sftp.lastErrorText!)")
