web 开发过程中经常会需要进行参数验证, Laravel 中我们常用 validator 或者 request 这两种方法来进行验证, 但是这两种验证都不是很方便进行自定义提示信息, 自定义验证规则, 所以下面来介绍一种很方便的用法:
新建抽象类
- <?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()
- {
- }
- }
新建中间件
- <?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);
- }
- }
新建 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' => '必填',
- 'name.min' => '最少 1 个字符',
- 'name.test' => '测试',
- );
- /**
- * 自定义验证规则或者扩展 Validator 类
- */
- public function before()
- {
- $this->extend('test', function ($attribute, $value, $parameters) {
- return bool;
- });
- }
- }
路由中如何使用
Route::post('/', ['middleware' => ['valiAdmin:Test'], 'uses' => 'IndexController@test']);
具体使用可以自行配置~
