How to use laravel's validator verification method elegantly

Parameter verification is often needed in the development process of web. In laravel, we often use validator or request to verify, but these two kinds of verification are not very convenient to customize prompt information and verification rules, so here is a very convenient usage:

New abstract class

<?php

namespace App\Http\Validators;

use Validator;

abstract class AbstractValidator
{

 /**
  * Validator
  *
  * @var \Illuminate\Validation\Factory
  */
 protected $validator;

 /**
  * Validation data key => value array
  *
  * @var array
  */
 protected $data = array();

 /**
  * Validation errors
  *
  * @var array
  */
 protected $errors = array();

 /**
  * Validation rules
  *
  * @var array
  */
 protected $rules = array();

 /**
  * Validation messages
  *
  * @var array
  */
 protected $messages = array();

 /**
  * Validation codes
  *
  * @var array
  */
 protected $codes = array();

 public function __construct(array $data)
 {
  $this->data = $data;
  $this->before();
  $this->validator = Validator::make($this->data, $this->rules, $this->messages);
  $this->after();
 }

 /**
  * Set data to validate
  *
  * @return validator
  */
 public function getValidator()
 {
  return $this->validator;
 }

 /**
  * Set data to validate
  *
  * @return $this
  */
 public function with(array $data)
 {
  $this->data = $data;
  $this->before();
  $this->validator = $this->validator->make($this->data, $this->rules, $this->messages);
  $this->after();
  return $this;
 }

 /**
  * Validation passes or fails
  *
  * @return boolean
  */
 public function passes()
 {
  if ($this->validator->fails()) {
   $this->errors = $this->validator->messages();

   return false;
  }

  return true;
 }

 /**
  * Return errors, if any
  *
  * @return array
  */
 public function errors()
 {
  return $this->errors;
 }

 /**
  * Return errors codes, if any
  *
  * @return array
  */
 public function getCodes()
 {
  return $this->codes;
 }

 /**
  * getRules
  *
  * @return array
  */
 public function getRules()
 {
  return $this->rules;
 }

 /**
  * getData
  *
  * @return array
  */
 public function getData()
 {
  return $this->data;
 }

 /**
  * getErrors
  *
  * @return array
  */
 public function getErrors()
 {
  return $this->errors;
 }

 /**
  * getMessages
  *
  * @return array
  */
 public function getMessages()
 {
  return $this->messages;
 }

 /**
  * setRule
  *
  * @param string $key
  * @param string $value
  *
  * @return $this
  */
 public function setRule($key, $value)
 {
  $this->rules[$key] = $value;

  return $this;
 }

 /**
  * emptyRules
  *
  * @return $this
  */
 public function emptyRules()
 {
  $this->rules = array();

  return $this;
 }

 /**
  * sometimes
  *
  * @param string  $attribute
  * @param string|array $rules
  * @param callable  $callback
  *
  * @return $this
  */
 public function sometimes($attribute, $rules, callable $callback)
 {
  $this->validator->sometimes($attribute, $rules, $callback);

  return $this;
 }

 /**
  * resolver
  *
  * @param Closure $resolver
  *
  * @return $this
  */
 public function resolver(Closure $resolver)
 {
  Validator::resolver($resolver);

  return $this;
 }

 /**
  * replacer
  *
  * @param Closure $resolver
  *
  * @return $this
  */
 public function replacer($replace, Closure $resolver)
 {
  Validator::replacer($replace, $resolver);

  return $this;
 }

 /**
  * extendImplicit
  *
  * @param Closure $resolver
  *
  * @return $this
  */
 public function extendImplicit($extendImplicit, Closure $resolver)
 {
  Validator::extendImplicit($extendImplicit, $resolver);

  return $this;
 }

 /**
  * extend
  *
  * @param string   $rule
  * @param \Closure|string $extension
  * @param string   $message
  *
  * @return $this
  */
 public function extend($rule, $extension, $message = null)
 {
  Validator::extend($rule, $extension, $message);

  return $this;
 }

 /**
  * before (extend(),resolver())
  *
  * @return $this
  */
 public function before()
 {
 }

 /**
  * after(sometimes())
  *
  * @return $this
  */
 public function after()
 {
 }
}

New middleware

<?php

namespace App\Http\Middleware;

use Closure;
use \Illuminate\Http\Request;

class ValidateAdminMiddleware
{
 /**
  * This namespace is applied to the controller routes in your routes file.
  *
  * In addition, it is set as the URL generator's root namespace.
  *
  * @var string
  */
 protected $namespace = 'App\Http\Validators';

 /**
  * Handle an incoming request.
  *
  * @param \Illuminate\Http\Request $request
  * @param \Closure     $next
  *
  * @return mixed
  */
 public function handle(Request $request, Closure $next, $validator = null)
 {
  if ($request->isMethod('POST')) {
   $type = $request->segment(1);
   if ($validator) {
    $validator = $this->namespace . '\\' . studly_case($type) . '\\' . studly_case($validator) . 'Validator';
    $validator = new $validator($request->all());

    if (!$validator->passes()) {
     if ($request->isAjax()) {
      return $validator->errors()->first();
     } else {
      return redirect()->back()
      ->withErrors($validator->getValidator())
      ->withInput();
     }
    }
   }
  }
  return $next($request);
 }
}

New TestTestValidator

<?php

namespace App\Http\Validators\Admin;

use App\Http\Validators\AbstractValidator;

class TestValidator extends AbstractValidator
{
 /**
  * Validation rules
  *
  * @var Array
  */
 protected $rules = array(
  'name' => ['required', 'test', 'min:1'],
 );

 /**
  * Validation messages
  *
  * @var Array
  */
 protected $messages = array(
  'name.required' => ' Required ',
  'name.min' => ' Minimum 1 Characters ',
  'name.test' => ' Test ',
 );

 /**
  *  Custom validation rules or extensions Validator Class 
  */
 public function before()
 {
  $this->extend('test', function ($attribute, $value, $parameters) {
   return bool;
  });
 }
}

How to use in routing

Route::post('/', ['middleware' => ['valiAdmin:Test'], 'uses' => 'IndexController@test']);

Specific use can be configured by yourself ~
