Hyperf2.1框架中验证器的使用流程步骤

官方手册上写着hyperf/validation 衍生于illuminate/validation，熟悉laravel的就不过多的介绍，不熟悉的自行搜索了解一下，我这里直接开始体验。

手册上也介绍了两种：

一.是创建表单验证类

对于复杂的验证场景，您可以创建一个 表单请求(FormRequest)，表单请求是包含验证逻辑的一个自定义请求类，表单验证类会生成于 app\Request 目录下

二.手动创建验证器

如果您不想使用 表单请求(FormRequest) 的自动验证功能，可以通过注入 ValidatorFactoryInterface 接口类来获得验证器工厂类，然后通过 make 方法手动创建一个验证器实例

1.开始安装组件包

[[email protected] hyperf-skeleton]# composer require hyperf/validation
Using version ^2.1 for hyperf/validation
./composer.json has been updated
Running composer update hyperf/validation
Loading composer repositories with package information

2.发布 Translation 组件的文件

[[email protected] hyperf-skeleton]# php bin/hyperf.php vendor:publish hyperf/translation
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\Config\Listener\RegisterPropertyHandlerListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\Paginator\Listener\PageResolverListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\ExceptionHandler\Listener\ExceptionHandlerListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\DbConnection\Listener\RegisterConnectionResolverListener listener.
[hyperf/translation] publishes [config] successfully.

3.发布验证器组件的文件

[[email protected] hyperf-skeleton]# php bin/hyperf.php vendor:publish hyperf/validation
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\Config\Listener\RegisterPropertyHandlerListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\Paginator\Listener\PageResolverListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\ExceptionHandler\Listener\ExceptionHandlerListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\DbConnection\Listener\RegisterConnectionResolverListener listener.
[hyperf/validation] publishes [zh_CN] successfully.
[hyperf/validation] publishes [en] successfully.

4.添加中间件 （在config/autoload/middlewares.php文件中）

return [
    'http' => [
        // 数组内配置您的全局中间件，顺序根据该数组的顺序
        \Hyperf\Validation\Middleware\ValidationMiddleware::class
    ],
];

5.添加异常处理器 （在config/autoload/exceptions.php文件中）

return [
    'handler' => [
        'http' => [
            \Hyperf\Validation\ValidationExceptionHandler::class,
        ],
    ],
];

这里测试方式1 (就用登录控制器测试) 

创建表单验证类

[[email protected] hyperf-skeleton]# php bin/hyperf.php gen:request FooRequest
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\Config\Listener\RegisterPropertyHandlerListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\Paginator\Listener\PageResolverListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\ExceptionHandler\Listener\ExceptionHandlerListener listener.
[DEBUG] Event Hyperf\Framework\Event\BootApplication handled by Hyperf\DbConnection\Listener\RegisterConnectionResolverListener listener.
App\Request\FooRequest created successfully.

启动hyperf框架

[[email protected] hyperf-skeleton]# php bin/hyperf.php start

在app\Request\FooRequest.php中配置规则

    public function rules(): array
    {
        return [
            'email' => 'required|email',
            'password' => 'required|min:6|max:12',
        ];
    }

控制器UserController.php中使用 （其他代码已删除）

<?php
declare(strict_types=1);
namespace App\Controller;

use App\Request\FooRequest;
class UserController extends AbstractController
{
    public function login(FooRequest $request)
    {
            // 获取通过验证的数据...
            $validated = $request->validated();
     }
}

这就完了 通过不了规则 直接提示规则信息

我们在测试方式2  

手动创建验证器

同样的控制器UserController.php中使用

<?php
declare(strict_types=1);
namespace App\Controller;

use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\Validation\Contract\ValidatorFactoryInterface;
class UserController extends AbstractController
{
    /**
     * @Inject()
     * @var ValidatorFactoryInterface
     */
    protected $validationFactory;
    public function login(RequestInterface $request)
    {
            // 获取通过验证的数据...
            //$validated = $request->validated();
            $validator = $this->validationFactory->make(
                $request->all(),
                [
                    'email' => 'required|email',
                    'password' => 'required|min:6|max:12',
                ]
            );
            if ($validator->fails()){
                // Handle exception
                $data = array('error' => 0, 'info' => $validator->errors()->first());
                return $data;
            }

一般简单的验证就用这个，方便
