为Slim 4框架的请求验证库。它使用respect-validation库。

目录

• 安装
• 用法

安装

通过Composer

$ composer require benycode/slim-request-validation

需要Slim 4。

用法

创建一个规则类

use BenyCode\Slim\Validation\Rule\RequestValidationRuleInterface;
use Respect\Validation\Validator;

final class AnyRuleClass implements RequestValidationRuleInterface
{
    public function rules(): array
    {
        return [
          'name' => Validator::alpha(),
          'url' => Validator::filterVar(FILTER_VALIDATE_URL),
        ];
    }
    
    public function messages(): array
    {
        return [
            'filterVar' => '{{name}} must be valid modified message.',
        ];
    }
}

向路由添加一个中间件

use BenyCode\Slim\Validation\Middleware\RequestValidationExceptionMiddleware;
use BenyCode\Slim\Validation\Transformer\RequestValidatorTransformFactory;
use BenyCode\Slim\Validation\Encoder\JsonEncoder;

$app = new \Slim\App();

$app->post('/api/any_end_point',function ($req, $res, $args) {
 
})
->add(new RequestValidationExceptionMiddleware(new RequestValidatorTransformFactory(), new JsonEncoder()))
->add(new RequestValidation([
	new AnyRuleClass(),
]))	
;

$app->run();

保持代码整洁并分割规则

use BenyCode\Slim\Validation\Middleware\RequestValidationExceptionMiddleware;
use BenyCode\Slim\Validation\Transformer\RequestValidatorTransformFactory;
use BenyCode\Slim\Validation\Encoder\JsonEncoder;

$app = new \Slim\App();

$app->post('/api/any_end_point',function ($req, $res, $args) {
 
})
->add(new RequestValidationExceptionMiddleware(new RequestValidatorTransformFactory(), new JsonEncoder()))
->add(new RequestValidation([
	new AnyRuleClass(),
	new AppendedRuleClass(),
	new AppendedRule2Class(),
	new AppendedRule3Class(),
	....
]))	
;

$app->post('/api/any_end_point2',function ($req, $res, $args) {
 
})
->add(new RequestValidationExceptionMiddleware(new RequestValidatorTransformFactory(), new JsonEncoder()))
->add(new RequestValidation([
	new AnyRuleClass(),
	new AppendedRule3Class(),
	....
]))	
;

$app->run();
