Laravel 回傳 json的亂碼解決方式

在Laravel中我們要產出json格式的話,一般只要

Route::get('json', function () {
  $users = DB::table('users')->get();
  return Response::json($users);
}

但是遇到中文時,會出現有亂碼的問題,解決很簡單

Route::get('json', function () {
    $headers = array('Content-Type' => 'application/json; charset=utf-8');
    $users = DB::table('users')->get();
    return Response::json($users, 200, $headers, JSON_UNESCAPED_UNICODE);
});
