SFTP Sync Download Tree w/ Must-Match Directory Constraints

See more SFTP Examples

Demonstrates how SFTP synchronize a directory tree in the download direction, but only entering directories matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Objective-C

#import <CkoSFtp.h>
#import <NSString.h>

BOOL success = NO;

CkoSFtp *sftp = [[CkoSFtp alloc] init];

success = [sftp Connect: @"my-ssh-server.com" port: [NSNumber numberWithInt: 22]];
if (success == YES) {
    success = [sftp AuthenticatePw: @"mySshLogin" password: @"mySshPassword"];
}

if (success == YES) {
    success = [sftp InitializeSftp];
}

if (success != YES) {
    NSLog(@"%@",sftp.LastErrorText);
    return;
}

//  Possible synchronization modes are:
//  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.

//  Only enter remote directories named either "data" or matching "x*"
sftp.SyncMustMatchDir = @"data; x*";

//  Imagine our remote directory tree has these files and directories:

//  	accentedLatin1.txt
//  	accentedUtf8.txt
//  	alice.key
//  	anter_cert.pem
//  	chiliPepper.gif
//  	helloWorld.pdf
//  	abc/chiliPepper.gif
//  	abc/ghk/
//  	data/chiliPepper.gif
//  	data/xyz/dkimHtmlBody.txt
//  	data/xyz/dkimVerifyTest.eml
//  	data/xyz/emailForCreateDsn.eml
//  	text/frenchUtf8.txt
//  	text/helloWorld.txt
//  	text/PolishEmailBody.txt
//  	text/something/
