include("chilkat.php");

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

$http = new CkHttp();

// To use HTTP Digest Authentication:
$http->put_Login('myLogin');
$http->put_Password('myPassword');
$http->put_DigestAuth(true);

// If you would like to see the HTTP session log to see how 
// HTTP digest authentication worked.
$http->put_SessionLogFilename('c:/temp/qa_output/sessionLog.txt');

// Run the test using this URL with the credentials above.  
// (Works while httpbin.org keeps the test endpoint available.)
$jsonResponse = $http->quickGetStr('https://httpbin.org/digest-auth/auth/myLogin/myPassword');
if ($http->get_LastMethodSuccess() == false) {
    print $http->lastErrorText() . "\n";
    exit;
}

print 'Response status code: ' . $http->get_LastStatus() . "\n";

print $jsonResponse . "\n";

// Output:

// Response status code: 200
// {
//   "authenticated": true, 
//   "user": "myLogin"
// }
