在你的创建方法中，你不需要调用验证服务，尝试使用$this->validator->getErrors()，你的情况可能是这样的：
return redirect()->to('/Create')->withInput()->with('errors', $this->validator->getErrors());
或者可能是这样的：
return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
而且您不再需要在视图中检查验证，只需检查会话中是否有错误：
<?php if (session()->has('errors')) : ?>
<ul class="alert alert-danger">
<?php foreach (session('errors') as $error) : ?>
<li><?= $error ?></li>
<?php endforeach ?>
</ul>
<?php endif ?>
