使用laravel框架读取在jquery中使用post发送的JSON数据

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))
    {
    ...
    }
}

Laravel 5.3 expects input to be sent in array format https://laravel.com/docs/5.3/requests#retrieving-input

Request sent through jQuery

$.ajax({
        url: 'http://weburl.com/api/user/create',
        dataType: 'json',
        type: 'POST',
        data: {'user': user},
        success: function(data) {
            this.setState({data: data});
        }.bind(this),
        error: function(xhr, status, err) {
            console.error(null, status, err.toString());
        }.bind(this)
    });

Laravel UserController::create

public function create(Request $request)
{

    $user = new User();
    $user->name = $request->input('user.name');
    $user->email = $request->input('user.email');
    $user->password = $request->input('user.password');

    $user->save();

    return response($user, 201);
}

In a Laravel 5.2 controller's method you could do this:

public function store(Request $request)
{
    $items = $request->input('items');

    return [
        'error' => false,
        'items' => $items
    ];
}
