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. Rust

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

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

// Set some timeouts, in milliseconds:
sftp.set_connect_timeout_ms(5000);
sftp.set_idle_timeout_ms(10000);

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
let hostname = "sftp.example.com".to_string();
let port = 22;
if sftp.connect(&hostname, port).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
if sftp.authenticate_pw("myLogin", "myPassword").is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// After authenticating, the SFTP subsystem must be initialized:
if sftp.initialize_sftp().is_err() {
    println!("{}", sftp.last_error_text());
    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.)
let Ok(handle) = sftp.open_file("hamlet.xml", "writeOnly", "createTruncate") else {
    println!("{}", sftp.last_error_text());
    return;
};

// Upload from the local file to the SSH server.
if sftp.upload_file(&handle, "c:/temp/hamlet.xml").is_err() {
    println!("{}", sftp.last_error_text());
    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.
if sftp.close_handle(&handle).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

println!("Success.");
