to get custom error message you need to pass custom error message on third parameter,like that
要获取自定义错误消息，您需要在第三个参数上传递自定义错误消息，就像这样

$request,
['thing' => 'required'],

);

$messages = [
'required' => 'The :attribute field is required.',
];
$validator = Validator::make($input, $rules, $messages);
"In most cases, you will probably specify your custom messages in a language file instead of passing them directly to the Validator. To do so, add your messages to custom array in the resources/lang/xx/validation.php language file."
“在大多数情况下，您可能会在语言文件中指定您的自定义消息，而不是将它们直接传递给验证器。为此，请将您的消息添加到 resources/lang/xx/validation.php 语言文件中的自定义数组。”

You need to first add following lines in view page where you want to show the Error message:
您需要首先在要显示错误消息的视图页面中添加以下行：
<div class="row">
<div class="col-md-4 col-md-offset-4 error">
<ul>
@foreach($errors->all() as $error)
<li>{{$error}}</li>
@endforeach
</ul>
</div>
</div>
Here is a demo controller by which error message will appear on that page:
这是一个演示控制器，错误消息将显示在该页面上：
public function saveUser(Request $request)
{
$this->validate($request,[
'name' => 'required',
'email' => 'required|unique:users',
]);
$user=new User();
$user->name= $request->Input(['name']);
$user->email=$request->Input(['email']);
$user->save();
return redirect('getUser');
}
