README

基于 Hyperf 框架的 DTO 类映射

优点

• 请求参数映射到PHP类
• 代码可维护性好，扩展性好
• 支持数组，递归，嵌套
• 支持框架数据验证器

注意

• 模型类需要手工编写
• php >= 8.1

安装

composer require tangwei/dto

使用

1. 使用

注解

命名空间:Hyperf\DTO\Annotation\Contracts

RequestBody

• 获取Body参数

public function add(#[RequestBody] DemoBodyRequest $request){}

RequestQuery

• 获取GET参数

public function add(#[RequestQuery] DemoQuery $request){}

RequestFormData

• 获取表单请求

public function fromData(#[RequestFormData] DemoFormData $formData){}

• 获取文件(和表单一起使用)

#[ApiFormData(name: 'photo', type: 'file')]

• 获取Body参数和GET参数

public function add(#[RequestBody] DemoBodyRequest $request, #[RequestQuery] DemoQuery $query){}

注意: 同一个方法不能同时存在RequestBody和RequestFormData注解

示例

控制器

#[Controller(prefix: '/demo')]
#[Api(tags: 'demo管理', position: 1)]
class DemoController extends AbstractController
{
    #[ApiOperation(summary: '查询')]
    #[PostMapping(path: 'index')]
    public function index(#[RequestQuery] #[Valid] DemoQuery $request): Contact
    {
        $contact = new Contact();
        $contact->name = $request->name;
        var_dump($request);
        return $contact;
    }

    #[PutMapping(path: 'add')]
    public function add(#[RequestBody] DemoBodyRequest $request, #[RequestQuery] DemoQuery $query)
    {
        var_dump($query);
        return json_encode($request, JSON_UNESCAPED_UNICODE);
    }

    #[PostMapping(path: 'fromData')]
    public function fromData(#[RequestFormData] DemoFormData $formData): bool
    {
        $file = $this->request->file('photo');
        var_dump($file);
        var_dump($formData);
        return true;
    }

    #[GetMapping(path: 'find/{id}/and/{in}')]
    public function find(int $id, float $in): array
    {
        return ['$id' => $id, '$in' => $in];
    }

}

验证器

基于框架的验证

安装hyperf框架验证器hyperf/validation, 并配置(已安装忽略)

• 注解 Required Between Date Email Image Integer Nullable Numeric Url Validation
• 校验生效

只需在控制器方法中加上 #[Valid] 注解

public function index(#[RequestQuery] #[Valid] DemoQuery $request){}

class DemoQuery
{
    public string $name;

    #[Required]
    #[Integer]
    #[Between(1,5)]
    public int $num;
}

• Validation

rule 支持框架所有验证

• 自定义验证注解

只需继承Hyperf\DTO\Annotation\Validation\BaseValidation即可

#[Attribute(Attribute::TARGET_PROPERTY)]
class Image extends BaseValidation
{
    protected $rule = 'image';
}

RPC 返回PHP对象

aspects.php中配置

return [
    \Hyperf\DTO\Aspect\ObjectNormalizerAspect::class
]

当框架导入 symfony/serializer (^5.0) 和 symfony/property-access (^5.0) 后，并在 dependencies.php 中配置一下映射关系

use Hyperf\Serializer\SerializerFactory;
use Hyperf\Serializer\Serializer;

return [
    Hyperf\Contract\NormalizerInterface::class => new SerializerFactory(Serializer::class),
];
