FTP Non-Recursive Sync Directory (Download)

See more FTP Examples

Download files from the server that have filenames matchhing a pattern, and don't yet exist in a local 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();

ftp.set_hostname("ftp.example.com");
ftp.set_username("myUsername");
ftp.set_password("myPassword");
ftp.set_port(21);
ftp.set_auth_tls(true);

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

// Change to the remote directory where the files are located.
// This step is only necessary if the files are not in the root directory
// of the FTP account.
if ftp.change_remote_dir("qa").is_err() {
    println!("{}", ftp.last_error_text());
    return;
}

// Indicate that we only want to download files with filenames ending in ".txt"
ftp.set_sync_must_match("*.txt");

// Modes for synchronization are as follows:
// mode=0: Download all files
// mode=1: Download all files that do not exist on the local filesystem.
// mode=2: Download newer or non-existant files.
// mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
// mode=5: Download only missing files or files with size differences.
// mode=6: Same as mode 5, but also download newer files.
// mode=99: Do not download files, but instead delete remote files that do not exist locally.
let mode = 1;

// Download all files matching "*.txt" from the current remote ftp directory.
// The files are downloaded into c:/temp/qa_output
if ftp.sync_local_dir("c:/temp/qa_output", mode).is_err() {
    println!("{}", ftp.last_error_text());
    return;
}

// Perhaps we wish to delete the files we just downloaded from the server..
let st = chilkat::StringTable::new();
ftp.get_synced_files(&st);

let num_files = st.count();
let mut i = 0;
