您可以通过以下方式在视图中获取错误信息：
@if (count($errors) > 0)
<div class="alert alert-danger alert-dismissable mb30 rtl yekan">
<button aria-hidden="true" data-dismiss="alert" class="close" type="button">×</button>
<ul class="list">
@foreach($errors->all() as $err)
<li class="liste-item">{{ $err }}</li>
@endforeach
</ul>
</div>
@endif
如果没有例外，那么验证成功了，对吗？通常，如果验证失败，则会创建一个重定向响应，其中错误会在会话中闪烁。因此，如果在默认重定向位置呈现错误，您应该会看到这些错误，但我希望看到这些消息，因为我不知道我的代码是否有效。在/category/list视图中，您需要有一个呈现消息的位置。检查如何渲染错误。您还需要检查session:：是否也有“create”并呈现该消息
