SCP Download Text File to String Variable

See more SCP Examples

Downloads a file using the SCP protocol (Secure Copy Protocol over SSH), from a specific remote directory located on the SSH server directly into a string variable. Rust

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

let ssh = chilkat::Ssh::new();

// Hostname may be an IP address or hostname:
let hostname = "www.some-ssh-server.com".to_string();
let port = 22;

// Connect to an SSH server:
if ssh.connect(&hostname, port).is_err() {
    println!("{}", ssh.last_error_text());
    return;
}

// Wait a max of 5 seconds when reading responses..
ssh.set_idle_timeout_ms(5000);

// Authenticate using login/password:
if ssh.authenticate_pw("myLogin", "myPassword").is_err() {
    println!("{}", ssh.last_error_text());
    return;
}

// Once the SSH object is connected and authenticated, we use it
// in our SCP object.
let scp = chilkat::Scp::new();

if scp.use_ssh(&ssh).is_err() {
    println!("{}", scp.last_error_text());
    return;
}

// This downloads a file from the "repositor/xml/" subdirectory (relative to the SSH user account's HOME directory).  
let remote_path = "repository/xml/hamlet.xml".to_string();

// The byte representation of the remote text file (i.e. the charset) must be
// indicated to allow the receiving software to correctly interpret the incoming
// bytes as the correct chars.
// See https://www.chilkatsoft.com/p/p_463.asp for a list of valid charset names.
let charset = "utf-8".to_string();

let Ok(file_contents) = scp.download_string(&remote_path, &charset) else {
    println!("{}", scp.last_error_text());
    return;
};

println!("Received file:");
println!("{}", file_contents);

println!("SCP download string success.");

// Disconnect
ssh.disconnect();
