更新
我将

和以下内容添加到

sample.blade.php

中。然而，它不能解决问题

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

sample.blade.php

<script type="text/javascript">
$("input.dog_check").click(function(){
  var amount = 10000;
  var dataString = 'amount='+amount;
  console.log(dataString);
  $.ajax({
    type:'POST',
    data:dataString,
    url: 'save_temporary_data',
    success:function(data) {
      alert(data);
    }
  });
});
</script>

可参考下页解决此问题。感谢‌-500内部服务器错误？rq=1

没有错误，任何人都不能做任何事情您可以手动检查日志。输入/存储/日志。但是如果您想在“现场”看到错误，请执行以下操作。在提交之前，打开开发者控制台并转到networking选项卡。提交ajax请求。您将在“网络”选项卡中收到红色请求。单击它，右侧是预览选项卡。 “预览”选项卡中将显示laravel格式的消息。希望这对您的调试有所帮助

<meta name="csrf-token" content="{{ csrf_token() }}" />
<script>
var CSRF_TOKEN = $('meta[name="csrf-token"]').attr('content');
jQuery.ajax({
            type:'POST',
            url :"{{url('save_temporary_data')}}",
            data:{_token: CSRF_TOKEN,amount:amount},
            success:function(data){
                alert(data);
            }
        });
</script>

内部控制器

public function saveTemporaryData(Request $request){
   echo $request['amount'];
}

可能重复查看

/storage/logs

，查看发生了什么错误，并将其发布到此处。此外，如果您使用的是Laravel，为什么不使用Elounce或querybuilder？是的，检查您的日志，它将立即显示您如何处理存在的问题
