如何在laravel中使用ajax添加会话数据

<button id="add-data-btn">添加数据</button>

<script>
    $(document).ready(function() {
        $('#add-data-btn').click(function() {
            $.ajax({
                url: '/add-data',
                method: 'POST',
                data: {
                    _token: '{{ csrf_token() }}'
                },
                success: function(response) {
                    // 处理成功响应
                    console.log(response);
                },
                error: function(xhr) {
                    // 处理错误响应
                    console.log(xhr.responseText);
                }
            });
        });
    });
</script>

Route::post('/add-data', 'DataController@addData');

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class DataController extends Controller
{
    public function addData(Request $request)
    {
        $data = '要添加的数据';
        $request->session()->put('data', $data);

        return response()->json(['message' => '数据已添加到会话中']);
    }
}
