(PHP Extension) Duplicate curl -u user:password with Chilkat HTTP

Demonstrates how to duplicate a curl command that uses the -u username:password option. (This assumes HTTP Basic Authentication, and Chilkat requires Basic authentication to be over a TLS connection.)

Duplicates the following curl command:

curl https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "Client-Id:Secret" \
  -d "grant_type=client_credentials"

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$http = new CkHttp();
$req = new CkHttpRequest();

//  The AddHeader method corresponds to the curl "-H" argument.
$req->AddHeader('Accept','application/json');
$req->AddHeader('Accept-Language','en_US');

//  The curl "-d" argument specifies the HTTP request body.  In this case,
//  we're sending an application/x-www-form-urlencoded request, and therefore
//  the body contains the URL-encoded query parameters.
$req->AddParam('grant_type','client_credentials');

$http->put_Login('PAYPAL_REST_API_CLIENT_ID');
$http->put_Password('PAYPAL_REST_API_SECRET');

//  Sends a POST request where the Content-Type is application/x-www-form-urlencoded
// resp is a CkHttpResponse
$resp = $http->PostUrlEncoded('https://api.sandbox.paypal.com/v1/oauth2/token',$req);
if ($http->get_LastMethodSuccess() != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

if ($resp->get_StatusCode() != 200) {
    print 'Error status code: ' . $resp->get_StatusCode() . "\n";
    print $resp->bodyStr() . "\n";

    exit;
}

//  The JSON response is in the resp BodyStr property
print $resp->bodyStr() . "\n";
print '-- Success.' . "\n";
