(Perl) 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"

use chilkat();

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

$http = chilkat::CkHttp->new();
$req = chilkat::CkHttpRequest->new();

#  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 HttpResponse
$resp = $http->PostUrlEncoded("https://api.sandbox.paypal.com/v1/oauth2/token",$req);
if ($http->get_LastMethodSuccess() != 1) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

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

    exit;
}

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