如何在ajax调用中将数组传递给控制器​​并使用Symfony3返回它

Question

嗨，谢谢你的帮助，我有一个ajax调用我希望发送给Controller的数据，所以我可以在以后删除指定的数据。目前我想从控制器显示给定的javascript。提前抱歉我的英语，这不是我的第一语言。

它当前正在返回一个JsonResponse来测试该方法是否被调用但是我想返回给定的javascript数组（playlogs），我该怎么做呢？

使用Javascript：

<script type="text/javascript">
       $(document).ready(function () {
           $('#deleteBtn').click(function () {
               var playlogs = [];

               $.each($("input[name='playlog']:checked"), function () {
                   playlogs.push($(this).val());
               });
               var confirmText = "Are you sure you want to delete this?";
               if (confirm(confirmText)) {
                   $.ajax({
                       type: "delete",
                       url: '{{ path('playlog_delete_bulk') }}',
                       data: playlogs,
                       success: function () {
                           alert("selected playlogs: " + playlogs.join(", "));
                       },
                   });
               }
               return false;
           });

       });
   </script>

PlayLogController中的deleteBulkAction：

/**
 * @Route("/delete/bulk", name="playlog_delete_bulk")
 */
public function deleteBulkAction(Request $request)
{
    if ($request->isXMLHttpRequest()) {
        return new JsonResponse(array('data' => 'Successfully called the named route playlog_delete_bulk  '));
    }

    return new Response('This is not ajax!', 400);
}

Answer 1

使用＆＃39;请求＆＃39; ParameterBag用于访问POST，PUT，PATCH和DELETE数据

  $password = $request->request->get('password');

和＆＃39;查询＆＃39; - 获取GET数据

  $pageNumber = $request->query->get('page');

Answer 2

您可以将播放列表作为json（或任何其他格式，取决于数据）发送。通过$request->getContent()读取请求体并在php数组中解码。

例：

<script type="text/javascript">
   $(document).ready(function () {
       $('#deleteBtn').click(function () {
           var playlogs = [];
           $.each($("input[name='playlog']:checked"), function () {
               playlogs.push($(this).val());
           });

           var confirmText = "Are you sure you want to delete this?";

           if (confirm(confirmText)) {
               $.ajax({
                   type: "delete",
                   url: '{{ path('playlog_delete_bulk') }}',
                   data: JSON.stringify(playlogs),
                   success: function (data) {
                      alert("selected playlogs: " + data.join(", "));
                   }
               });
           }
           return false;
       });

   });

/**
 * @Route("/delete/bulk", name="playlog_delete_bulk")
 */
public function deleteBulkAction(Request $request)
{
    if ($request->isXMLHttpRequest()) {
        return new JsonResponse(json_decode($request->getContent()));
    }

    return new Response('This is not ajax!', 400);
}
