AJAX request with laravel 5.2 error

Question

I have this ajax request in home.blade.php :

function send(event) {
    event.preventDefault();

    $.ajax({
        headers: {'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')},
        type: "POST",
        url: "{{ route('add_action') }}",
        data: {name: $("#name").val(), niceness: $("#niceness").val(), _token: "{{ Session::token() }}"}

    });

}

in the controller I have this postAction:

public function postInsertNiceAction(Request $request)
{
    $this->validate($request, [
        'name'     => 'required|alpha|unique:nice_actions',
        'niceness' => 'required|numeric',
    ]);

    $action = new  NiceAction();
    $action->name = ucfirst(strtolower($request['name']));
    $action->niceness = $request['niceness'];
    $action->save();
    $actions = NiceAction:: all();

    if ($request->ajax()) {
        return response()->json();
    }

    return redirect()->route('home');
}

I added this meta tag:

<meta name="_token" content="{{ csrf_token() }}">

so when I run this I got this error :

jquery-1.12.0.min.js:4 POST http://localhost:8000/do/add_action 422 (Unprocessable Entity)

I tried to change the version of the jQuery file but it's not working.

Any help will be appreciated!

I'm new to Laravel.

Thank you

Try this:

function send(event) {
    event.preventDefault();

    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
        }
    })

    $.ajax({
        type: "POST",
        url: "{{ route('add_action') }}",
        data: { name: $("#name").val(), niceness: $("#niceness").val() },
    });
