Ftp2 Debug Log File Path

Demonstrates how to use the DebugLogFilePath property to get information if a Chilkat method crashes or hangs.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

var ftp = new CkFtp2();

// ...
// ...

// Insert this code just before the method call that crashes or hangs.
ftp.VerboseLogging = true;
ftp.DebugLogFilePath = "/some/file/path/sftp_debug_log.txt";

// Make the call that crashes or hangs,
// for example, if the method is PutFile:

var remoteFilePath = "...";
var localFilePath = "...";
success = ftp.PutFile(localFilePath,remoteFilePath);

// Note: If the method returns control to your application code, then it did not crash within Chilkat.
// The DebugLogFilePath property causes all information that would be recorded in the LastErrorText to be emitted to the
// log file (with immediate file write flushing, i.e. no buffering).  Thus, in a crash situation,
// the log file will contain information up to the point of the crash.

if (success == false) {
    console.log(ftp.LastErrorText);
    return;
}
