FTP Sync Download Tree w/ Must-Match Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only for files matching a set of wildcard filenames.

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

C++

#include <CkFtp2.h>
#include <CkStringTable.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkFtp2 ftp;

    ftp.put_Hostname("ftp.something.com");
    ftp.put_Username("my_login");
    ftp.put_Password("my_password");

    //  Connect and login to the FTP server.
    success = ftp.Connect();
    if (success != true) {
        std::cout << ftp.lastErrorText() << "\r\n";
        return;
    }

    //  Set the current remote directory to the root of
    //  the tree to be downloaded.
    success = ftp.ChangeRemoteDir("/subDir1");
    if (success != true) {
        std::cout << ftp.lastErrorText() << "\r\n";
        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.

    //  This example will download all files, but only those files having filenames
    //  that match *.gif and *.eml

    //  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/

    //  Indicate that we only want to create auto-create local directories (if needed)
    //  for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
    //  true, then the corresponding local directory is created for each remote directory
    //  traversed regardless of whether files within are downloaded.
    ftp.put_SyncCreateAllLocalDirs(false);

    ftp.put_SyncMustMatch("*.eml; *.gif");
    int mode = 0;
    success = ftp.SyncLocalTree("c:/temp/subDir1",mode);
    if (success != true) {
        std::cout << ftp.lastErrorText() << "\r\n";
        return;
    }

    success = ftp.Disconnect();

    //  Show the files downloaded.
    CkStringTable st;
    ftp.GetSyncedFiles(st);

    int numFiles = st.get_Count();
    int i = 0;
    const char *remoteFilename = 0;
    while (i < numFiles) {
        std::cout << st.stringAt(i) << "\r\n";
        i = i + 1;
    }

    //  Output showing the files downloaded:

    //  chiliPepper.gif
    //  abc/chiliPepper.gif
    //  data/chiliPepper.gif
    //  data/xyz/dkimVerifyTest.eml
    //  data/xyz/emailForCreateDsn.eml
