使用laravel框架读取在jquery中使用post发送的JSON数据

Question

I have this codes,

var obj = '{"items":[{"Code":"c101","Description":"Car"}]}';
$.post('get-items',obj,function(){

});

I used this code,

file_get_contents('php://input')

Because I cant get the POST Data that is sent. Using the above code, I get the raw POST Data.

How can I read data sent without using file_get_contents('php://input')? Because I can't use file_get_contents('php://input').

Here is my Laravel controller function,

public function getItems()
{
    $data = file_get_contents('php://input');
    if(isset($data))
    {
    ...
    }
}
