Example

By Using The Builder

//it is always good to ship the component with a factory to easy up usage
use Net\Bazzline\Component\Curl\BuilderFactory;
use Net\Bazzline\Component\Curl\Option\Timeout;

$factory    = new BuilderFactory();
$builder    = $factory->create();
$url        = 'http://www.foo.bar';
$timeout    = new Timeout(10);  //set the timeout to 10 seconds

/**
 * you can also use:
 *  //assuming that $dispatcher is an instance of DispatcherInterface
 *  //assuming that $requestFactory is an instance of RequestFactory
 *  $builder->overwriteDispatcher($dispatcher);
 *  $builder->overwriteRequestFactory($requestFactory);
 */

$response = $builder->usePost()
    ->onTheUrl($url)
    ->withTheData($data)
    ->withTheParameters(array('descendingOrderBy' => 'id'))
    ->withTheOption($timeout)
    ->andFetchTheResponse();

/** 
 * you can also use:
 *  $builder->withTheHeaderLine($headLine)    //add the headline you want
 *  $builder->withResponseModifier($modifier) //add the response modifier you want
 */

echo 'content: ' . $response->content() . PHP_EOL;
echo 'content type: ' . $response->contentType() . PHP_EOL;
echo 'error:' . $response->error() . PHP_EOL;
echo 'error code:' . $response->errorCode() . PHP_EOL;
echo 'head lines: ' . var_export($response->headerLines(), true) . PHP_EOL;
echo 'status code: ' . $response->statusCode() . PHP_EOL;

By Using The Request

//it is always good to ship the component with a factory to easy up usage
$factory    = new Net\Bazzline\Component\Curl\RequestFactory();
$request    = $factory->create();
$url        = 'http://www.foo.bar';

$response = $request->get($url);

echo 'content: ' . $response->content() . PHP_EOL;
echo 'content type: ' . $response->contentType() . PHP_EOL;
echo 'error:' . $response->error() . PHP_EOL;
echo 'error code:' . $response->errorCode() . PHP_EOL;
echo 'head lines: ' . var_export($response->headerLines(), true) . PHP_EOL;
echo 'status code: ' . $response->statusCode() . PHP_EOL;

Post Request With Basic Authentication

//begin of runtime environments
$factory        = new BuilderFactory();

$data           = array(
    'there'     => 'is',
    'no'        => 'foo',
    'without'   => 'a bar'
);
$password       = '<super secret password>';
$username       = 'foo@bar.ru';
$url            = 'https://foo.bar.ru/api/my/rest/endpoint/v1';
//end of runtime environments

//begin building the request
$builder->asJson();
$builder->onTheUrl($url);
$builder->withTheData($data);
$builder->withTheOption(new SetBasicAuthentication());
$builder->withTheOption(new SetUsernameAndPassword($username, $password));
$builder->usePost();
//end building the request

$request = $builder->andFetchTheResponse();
echo PHP_EOL . 'dumping the request' . PHP_EOL;
var_dump($request);

Terms

  • Dispatcher
    • doing the curl request
    • if you want to use pure curl, use this class
  • Request
    • object oriented approach reflecting the request
    • HeadLine
      • object oriented http headers (list of available headers), start a pull request if you need more
    • Options
      • object oriented curl options, start a pull request if you need more
    • Parameters
      • all the parameters you want to add to your url - they are urlencoded automatically
    • Url
      • the url of your endpoint
  • Response
    • object oriented approach reflecting the response
    • ResponseBehaviour
      • interface to interact with the response
        • either modify the response (by creating a new one)
        • change the flow by throwing an exception if the response does not fits your needs (as example)
  • Builder
    • provides a fluent interface to easy up using curl
    • it takes care of all :-)

Not Available Curl Options

In general, the php version is limiting the available curl options. Furthermore, some options are not implemented because of their hardcoded usage in the Response or the Dispatcher (you can set it but they would be overwritten).

This options are:

  • used in the Request
    • CURLOPT_CUSTOMREQUEST
    • CURLOPT_HTTPHEADER
    • CURLOPT_POSTFIELDS
  • used in the Dispatcher
    • CURLINFO_HEADER_OUT
    • CURLOPT_HEADERFUNCTION
    • CURLOPT_RETURNTRANSFER

If you want to change this, you either have to extend the existing Request or Dispatcher object.
