Decorate your function/method by using middlewares in Laravel.
composer require istianxin/decorator-laravel
You can define a middleware similar to Laravel Middleware. It should be noticed that the first parameter of th handle method is not \Illuminate\Http\Request, but an array the parameters of the method/function to be decorated. Except for this, everything is the same as Laravel Middleware.
Here is an example:
class MultiplicationMiddleware
{
public function handle($data, $next, $factor = 1)
{
return $next($data) * $factor;
}
}
Except for middleware, decorator accepts two other parameters, callback and parameters, which are also the first two parameters of app()->call().
Callback is a callable, which can be invoked by app()->call() and call_user_func_array(), such as: DummyClass@method, a closure, [Dummyclass::class,staticMethod], [new DummyClass(), method], DummyClass::staticMethod.
Parameters is an array of parameters of the callbale.
$class = new class {
public function add($a, $b)
{
return $a + $b;
}
};
$a = 1;
$b = 2;
$factor = 3;
$decorator = new Decorator();
// classname with parameter
$middleware = MultiplicationMiddleware::class . ':' . $factor;
$result = $decorator->setCallback([$class, 'add'])
->setMiddleware($middleware)
->setParameters([$a, $b])
->decorate();
echo $result; // 9
$decorator->setMiddleware([
$object_middleware1,
middleware2::class,
middleware3:class:param1,param2,
$closure_middleware4
]);
or
$decorator->setMiddleware([
$object_middleware1,
middleware2::class
])->appendMiddleware([
middleware3:class:param1,param2,
$closure_middleware4
])
