Rust Requires Chilkat v11.0.0+

Co:Z SFTP Binary File Download (from z/OS IBM Mainframe)

See more SFTP Examples

Demonstrates how to download a binary file, such as a .zip, from a Co:Z SFTP server on a z/OS IBM Mainframe. Rust

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

let sftp = chilkat::SFtp::new();

// Connect to the SSH server.  
let hostname = "sftp.example.com".to_string();
let port = 22;
if sftp.connect(&hostname, port).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

if sftp.authenticate_pw("myLogin", "myPassword").is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

if sftp.initialize_sftp().is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// To download a binary file from the Co:Z SFTP server, 
// we must switch to binary mode in the following unconventional way.
// We pretend to fetch a directory listing for "/+mode=binary"
// This has the effect of putting the server in binary mode for transfers.
let Ok(handle) = sftp.open_dir("/+mode=binary") else {
    println!("{}", sftp.last_error_text());
    return;
};

// Download the "directory listing" (but it's not actually a directory listing, and we'll just discard it.)

let dir_listing = chilkat::SFtpDir::new();
if sftp.read_dir_listing(&handle, &dir_listing).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Close the directory handle:
if sftp.close_handle(&handle).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Download the binary file:
let local_file_path = "c:/temp/test.zip".to_string();
let remote_file_path = "test.zip".to_string();
if sftp.download_file_by_name(&remote_file_path, &local_file_path).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

println!("Success.");
