        <br><br>

        <ul>
        @foreach ($errors->all() as $error)
            <li>{{ $error }}</li>
        @endforeach
        </ul>

public function postAdd(Request $request)
{
    $validator = Validator::make($request->input('data'), [
        'name' => 'required|max:255',
        'body' => 'required',
    ]);
    if ($validator->fails()) {
        //验证不通过
        return redirect('message/add')
            ->withErrors($validator)
            ->withInput();
    }
    //验证通过，保存留言信息
    $message = new Message;
    $message->name = $request->name;
    $message->body = $request->body;
    $result = $message->save();
    return redirect('message/index');
