(Perl) Debugging with Socket Session Logging

Debugging with socket session logging.

The Chilkat Socket component provides properties for keeping a session log making it possible to see the exact bytes received and sent on a TCP/IP or SSL connection. To enable session logging, set the KeepSessionLog property = 1. The SessionLogEncoding property controls how binary, non-printable bytes are represented in the log. There are two possible settings: Possible values are "esc" and "hex". The default value is "esc".

When set to "hex", the bytes are encoded as a hexidecimalized string. The "esc" encoding is a C-string like encoding, and is more compact than hex if most of the data to be logged is text. Printable us-ascii chars are unmodified. Common "C" control chars are represented as "\r", "\n", "\t", etc. Non-printable and byte values greater than 0x80 are escaped using a backslash and hex encoding: \xHH. Certain printable chars are backslashed: SPACE, double-quote, single-quote, etc.

use chilkat();

$socket = new chilkat::CkSocket();

$success = $socket->UnlockComponent("Anything for 30-day trial");
if ($success != 1) {
    print $socket->lastErrorText() . "\r\n";

}

#  Enable session logging:
$socket->put_KeepSessionLog(1);
$socket->put_SessionLogEncoding("esc");

#  To demonstrate session logging, we'll connect to an
#  HTTP server and download the HTTP response header:
$ssl = 0;
$maxWaitMillisec = 20000;
$success = $socket->Connect("www.chilkatsoft.com",80,$ssl,$maxWaitMillisec);
if ($success != 1) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

#  Set maximum timeouts for reading an writing (in millisec)
$socket->put_MaxReadIdleMs(10000);
$socket->put_MaxSendIdleMs(10000);

#  The socket component includes a BuildHttpGetRequest
#  method for convenience. Build a GET and send it to
#  the web server:

$httpGet = $socket->buildHttpGetRequest("http://www.chilkatsoft.com/");

#  Send it...
$success = $socket->SendString($httpGet);
if ($success != 1) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

#  Read the response up to the first double CRLF:
$httpHeader = $socket->receiveUntilMatch("\r\n\r\n");
if ($socket->get_LastMethodSuccess() != 1) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

#  Close the connection with the server
#  Wait a max of 20 seconds (20000 millsec)
$success = $socket->Close(20000);

#  Display the session log:
print $socket->sessionLog() . "\r\n";

#  Show the HTTP response header:
print $httpHeader . "\r\n";
