(PHP ActiveX) HTTPS Windows Integrated Authentication

This example pertains to running on the Windows operating system only.

It provides guidance on how to send HTTP requests using the current logged-on Windows user credentials. This is where NTLM/Negotiate authentication is used, but the login/password credentials are not explicitly provided by the application, but are implicitly provided based on the Windows logged-on user (i.e. the Windows account for the running process).

<?php

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// Chilkat implements the NTLM protocol directly, which is how it can be used on non-Windows systems.
// However, Chilkat can also optionally use Microsoft's SSPI (see https://docs.microsoft.com/en-us/windows/desktop/secauthn/ssp-packages-provided-by-microsoft) 
// to allow for Windows Integrated Authentication.

// Setting the HTTP Login equal to the empty string, and the Password equal to the keyword "default"
// will cause Chilkat to use the Microsoft SSPI w/ integrated authentication.
$http->Login = '';
$http->Password = 'default';

// We can also explicitly indicate that NTLM or Negotiate authentication is to be used:
$http->NegotiateAuth = 1;

// Set various properties unrelated to authentication..
// Automatically follow redirects.
$http->FollowRedirects = 1;
// Give verbose logging in the LastErrorText (in case there are errors)
$http->VerboseLogging = 1;
// Optionally log the exact session to a file (for debugging)
$http->SessionLogFilename = 'c:/someDir/session.txt';
// Perhaps you wish to be seen as a browser on Mac OS X..
$http->UserAgent = 'Mozilla/5.0 (Windows NT; Windows NT 6.1; en-GB) AppleWebKit/534.6 (KHTML, like Gecko) Chrome/7.0.500.0 Safari/534.6';

// Note: If the result of authentication is to set Cookies that are used in subsequent requests,
// then make sure Chilkat both saves and sends cookies: 
$http->SaveCookies = 1;
$http->SendCookies = 1;
$http->CookieDir = 'memory';

// Send a GET request to a URL, using Windows Integrated Authentication...
$responseStr = $http->quickGetStr('https://somewhere.net/api/user');
if ($http->LastMethodSuccess != 1) {
    print $http->LastErrorText . "\n";
    exit;
}

print 'response status code = ' . $http->LastStatus . "\n";
print 'response header:' . "\n";
print $http->LastHeader . "\n";
print '----' . "\n";
print $responseStr . "\n";
