在我的控制器中，我有以下代码：
if (isset($request->validator) && $request->validator->fails())
{
$a =
[
"error_code" => 500,
"msg" => 'The given data was invalid.',
"errors" => $request->validator->errors()
];
$a = implode(" ",$a);
return back()->setStatusCode(422)->withErrors($request->validator->errors());
}
基本上，如果请求表单数据无效，则应该
但是问题在于，它仅遵循第一个规则（关于htpp代码），而没有遵循第二个规则。
即返回以下内容：

错误消息存储在会话中。要显示它们，您需要访问刀片文件中的会话，例如{{session('errors')->first('error1')}}。
