PHP Luminova: Incoming HTTP Request Management Class

The Request class represents an incoming HTTP request to a server, encapsulating various components such as headers, query parameters, form data, and uploaded files. This class offers a structured approach to access and manipulate incoming HTTP requests, including built-in authentication mechanisms to validate requests based on origin, proxies, or allowed domains.

Accessing the Request Object

The request object can be accessed in multiple ways, depending on the context. You can use the global helper function, the Factory class, or the Controller class.

Access Methods

1. Using Global Helper Function

$request = request();

2. Accessing Through the Factory Class

use Luminova\Application\Factory;

$request = Factory::request();

3. Initializing the Request Instance Directly

use Luminova\Http\Request;

$request = new Request();

4. Accessing in Controller Classes

If your controller extends BaseController:

$this->request->foo();

If your controller extends BaseViewController, you can access it in two ways:

Direct Access:

$this->request()->foo();

Initializing in the onCreate Method:

You can initialize the request instance once, then access it later:

$this->request(); // Initialize

// Then access it.
$this->request->foo();
