//=======================================

// 라라벨에서 POST 방식 사용시 주의할점

- CSRF 보안을 위해 토큰 추가 설정을 해야 에러가 나지 않는다.


    $.ajaxSetup({

        headers: {

            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')

        }

    });

//server.php

<?php
//header("Content-Type: application/json; charset=UTF-8");
error_reporting(0);

$rt = $_REQUEST['q'];
$gt = $_GET['q'];
$pt = $_POST['q'];

//echo "서버 응답: "."REQ=[".$rt."] , "."GET=[".$gt."] , "."POST=[".$pt."] "."id2=[".$id2."]";

$jq = json_decode($pt);
