Laravel 5.5 使用自定义消息进行验证

Question

我正在我的 Laravel 应用程序中处理密码更改表单。我想将验证器与自定义错误消息一起使用。

我的代码如下所示:

  $rules = [
    'username' => 'required|max:255',
    'oldpassword' => 'required|max:255',
    'newpassword' => 'required|min:6|max:255|alpha_num',
    'newpasswordagain' => 'required|same:newpassword',
  ];
  $messages = [
     'username.required' => Lang::get('userpasschange.usernamerequired'),
     'username.max:255' => Lang::get('userpasschange.usernamemax255'),
     'oldpassword.required' => Lang::get('userpasschange.oldpasswordrequired'),
     'oldpassword.max:255' => Lang::get('userpasschange.oldpasswordmax255'),
     'newpassword.required' => Lang::get('userpasschange.newpasswordrequired'),
     'newpassword.min:6' => Lang::get('userpasschange.newpasswordmin6'),
     'newpassword.max:255' => Lang::get('userpasschange.newpasswordmax255'),
     'newpassword.alpha_num' => Lang::get('userpasschange.newpasswordalpha_num'),
     'newpasswordagain.required' => Lang::get('userpasschange.newpasswordagainrequired'),
     'newpasswordagain.same:newpassword' => Lang::get('userpasschange.newpasswordagainsamenewpassword'),
 ];

  $validator = Validator::make($request->all(), $rules, $messages);
  $validator->setCustomMessages($messages);

  Log::debug("custommessages: " . json_encode($messages));
  Log::debug("messages: " . json_encode($validator->messages()));

在日志中 自定义消息是显示我的自定义消息，但在下一行中有原始 留言 .

我在 official doc 工作.

有人遇到过这个问题吗？

谢谢提前回答!

重写和推荐的方法。
引用手册https://laravel.com/docs/5.5/validation#creating-form-requests

使用请求文件。

运行 php artisan make:request UpdateUserPasswordRequest

写入请求文件

2020 年 2 月编辑:在最新版 Laravel 的授权方法中，可以使用全局 auth() 对象代替\Auth，因此\Auth::check() 将变为 auth()->check()。如果从框架中删除某些内容，两者仍然有效并且会更新

namespace App\Http\Requests;

class UpdateUserPasswordRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        // only allow updates if the user is logged in
        return \Auth::check();
        // edit you can now replace this with return auth()->check();
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'username' => 'required|max:255',
            'oldpassword' => 'required|max:255',
            'newpassword' => 'required|min:6|max:255|alpha_num',
            'newpasswordagain' => 'required|same:newpassword',
        ];
    }

    /**
     * Get the validation attributes that apply to the request.
     *
     * @return array
     */
    public function attributes()
    {
        return [
            'username'            => trans('userpasschange.username'),
            'oldpassword'             => trans('userpasschange.oldpassword'),
            'newpassword'             => trans('userpasschange.newpassword'),
            'newpasswordagain'       => trans('userpasschange.newpasswordagain'),
        ];
    }

    /**
     * Get the validation messages that apply to the request.
     *
     * @return array
     */
    public function messages()
    {
// use trans instead on Lang 
        return [
     'username.required' => Lang::get('userpasschange.usernamerequired'),
     'oldpassword.required' => Lang::get('userpasschange.oldpasswordrequired'),
     'oldpassword.max' => Lang::get('userpasschange.oldpasswordmax255'),
     'newpassword.required' => Lang::get('userpasschange.newpasswordrequired'),
     'newpassword.min' => Lang::get('userpasschange.newpasswordmin6'),
     'newpassword.max' => Lang::get('userpasschange.newpasswordmax255'),
     'newpassword.alpha_num' =>Lang::get('userpasschange.newpasswordalpha_num'),
     'newpasswordagain.required' => Lang::get('userpasschange.newpasswordagainrequired'),
     'newpasswordagain.same:newpassword' => Lang::get('userpasschange.newpasswordagainsamenewpassword'),
      'username.max' => 'The :attribute field must  have under 255 chars',
        ];
    }

在用户 Controller 中

<?php namespace App\Http\Controllers;


// VALIDATION: change the requests to match your own file names if you need form validation
use App\Http\Requests\UpdateUserPasswordRequest as ChangePassRequest;
//etc

class UserCrudController extends Controller
{
public function chnagePassword(ChangePassRequest $request)
{
 // save new pass since it passed validation if we got here
}
}
