Get FTP File Permissions

See more FTP Examples

_LANGUAGE_ example showing how to retrieve file permissions (via FTP) for each file in a remote directory. Rust

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

let ftp = chilkat::Ftp2::new();

// Set the various properties to establish the connection.
ftp.set_hostname("ftp.example.com");
ftp.set_username("login");
ftp.set_password("password");

// If SSL/TLS is required..
// See http://www.cknotes.com/determining-ftp2-connection-settings/ 
// for more information.
ftp.set_auth_tls(true);
ftp.set_passive_use_host_addr(true);

// Connect to the FTP server:
if ftp.connect_only().is_err() {
    println!("{}", ftp.last_error_text());
    return;
}

// Authenticate with the FTP server.
if ftp.login_after_connect_only().is_err() {
    println!("{}", ftp.last_error_text());
    return;
}

// To get file permissions in UNIX format, disallow MSLD:
ftp.set_allow_mlsd(false);

// To get file and sub-directory information, simply
// loop from 0 to ftp.GetDirCount() - 1
let mut i = 0;
let mut n = ftp.get_dir_count();
if n < 0 {
    println!("{}", ftp.last_error_text());
    return;
}

// Show the type of permissions information that is available.
// The two most common types are "mlsd" and "unix".  See the
// online reference documentation for more information.
if n > 0 {
    println!("The permissions format is: {}", ftp.get_perm_type(0).unwrap_or_default());
}

while i < n {

    // Display the permissions and filename
    println!("{} {}", ftp.get_permissions(i).unwrap_or_default(), ftp.get_filename(i).unwrap_or_default());

    i = i + 1;
}

// Assuming MLSD was possible, let's see the file permissions in MLSD format:
ftp.set_allow_mlsd(true);

// Clear the directory cache so we're forced to re-fetch the directory listing:
ftp.clear_dir_cache();

n = ftp.get_dir_count();
if n < 0 {
    println!("{}", ftp.last_error_text());
    return;
}

// Show the type of permissions information that is available.
// The two most common types are "mlsd" and "unix".  See the
// online reference documentation for more information.
if n > 0 {
    println!("----");
    println!("The permissions format is: {}", ftp.get_perm_type(0).unwrap_or_default());
}

i = 0;
while i < n {

    // Display the permissions and filename
    println!("{} {}", ftp.get_permissions(i).unwrap_or_default(), ftp.get_filename(i).unwrap_or_default());

    i = i + 1;
}

let _ = ftp.disconnect().is_ok();
