Laravel 4：如何修剪每个Input :: all（）数据？

My usual way of trimming user input in a laravel controller is like this:

public function __construct()
{
    if (isset($_POST)) $_POST = array_map('trim', $_POST);
    if (isset($_GET)) $_GET = array_map('trim', $_GET);
}

How do I trim an Input class in laravel in a similar way?

-- SOLVED --

Nevermind, I find Input::merge() already

add this line to trim all input:

Input::merge(array_map('trim', Input::all()));
