README

步骤 1: 下载包

打开命令行控制台，进入你的项目目录，并执行以下命令以下载此包的最新稳定版本

$ composer require relief_applications/symfony-request-validator-bundle @dev

此命令要求你全局安装Composer，具体请参阅Composer文档中的安装章节。

步骤 2: 启用包

然后，通过将其添加到项目中的app/AppKernel.php文件中注册的包列表中来启用该包

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new RA\RequestValidatorBundle\RARequestValidatorBundle(),
        );
    }
}

步骤 3: 配置

# app/config/services.yml according to your project path
imports:
    - { resource: "@RARequestValidatorBundle/Resources/config/services.yml" }

步骤 4: 默认路由

为了测试我们的默认控制器

# app/config/routing.yml according to your project path
RequestValidatorBundle:
    resource: "@RARequestValidatorBundle/Resources/config/routing.yml"

步骤 5: 使用方法

1. 定义自定义约束类

此类应扩展 RA\RequestValidatorBundle\RequestValidator\Constraints。约束列表可在此处找到

<?php
namespace RequestValidatorBundle\Custom;

use RA\RequestValidatorBundle\RequestValidator\Constraints as RequestValidatorConstraints;

use Symfony\Component\Validator\Constraints\Choice;
use Symfony\Component\Validator\Constraints\Collection;
use Symfony\Component\Validator\Constraints\GreaterThan;
use Symfony\Component\Validator\Constraints\NotBlank;
use Symfony\Component\Validator\Constraints\NotEqualTo;
use Symfony\Component\Validator\Constraints\Optional;
use Symfony\Component\Validator\Constraints\Type;

/**
 *  TopicsConstraints
 *
 * A special class for topic constraints
 */
class TopicsConstraints extends RequestValidatorConstraints
{

    protected function configure() : array
    {
        //Reusable rules can be store into variables starting by 'common'
        $commonCategoryId = new Optional ([
            new Type('numeric'),
            new GreaterThan(0)
        ]);
        $commonNotBlank = new NotBlank();

        return [
            'topics'    => [
                // rules for URI fields
                'query'     => new Collection([
                    'method'            => new Optional ([new Choice(['by'])]),
                    'category_id'       => $commonCategoryId
                ]),
                // rules for POSTED fields
                'request'    => new Collection([
                    'category_id'       => $commonCategoryId,
                    'title'             => $commonNotBlank,
                    'description'       => $commonNotBlank,
                    'message'           => $commonNotBlank
                ]),
            ],
            // rules for ANY fields
            'topics2'    => new Collection([
                'category_id'       => $commonCategoryId,
                'title'             => $commonNotBlank,
                'description'       => $commonNotBlank,
                'message'           => $commonNotBlank
            ]),
        ];
    }

}

2. 使用注解

<?php

//...
use RequestValidatorBundle\Custom\TopicsConstraints; //our custom constraints class
use RA\RequestValidatorBundle\Annotations\ValidateQuery;
use RA\RequestValidatorBundle\Annotations\ValidateRequest;


class TopicController extends Controller
{
    /**
    * @Get("/", name="get_all_topics")
    * @ValidateQuery( configuration="topics", constraintsClass=TopicsConstraints::class)
    * Get a table of all the topics
    */
    public function getAllAction(Request $request){
        $categoryId     = $request->get('category_id');
        //...
    }

    /**
    * @Post("/", name="create_topic")
    * @ValidateRequest( configuration="topics", constraintsClass=TopicsConstraints::class)
    * Get a table of all the topics
    */
    public function createAction(Request $request){
        $categoryId         = $request->request->get('category_id');
        $title              = $request->request->get('title');
        $description        = $request->request->get('description');
        $messageContent     = $request->request->get('message');
        //...
    }

3. 使用函数

<?php

//...
use RequestValidatorBundle\Custom\TopicsConstraints; //our custom constraints class
use RA\RequestValidatorBundle\RequestValidator\ValidationException as RequestValidatorValidationException;


class TopicController extends Controller
{
    /**
    * @Get("/", name="get_all_topics")
    * Get a table of all the topics
    */
    public function getAllAction(Request $request){
        try {
            $validator = $this->get('request_validator');
            $this->validator->validateQuery('topics',TopicsConstraints::class);
        } catch (RequestValidatorValidationException $e) {
            return new JsonResponse($e->getErrors(), $e->getCode());
        }

        $categoryId     = $request->get('category_id');
    }

    /**
    * @Post("/", name="create_topic")
    * Get a table of all the topics
    */
    public function createAction(Request $request){
        try {
            $validator = $this->get('request_validator');
            $this->validator->validateRequest('topics',TopicsConstraints::class);
        } catch (RequestValidatorValidationException $e) {
            return new JsonResponse($e->getErrors(), $e->getCode());
        }

        $categoryId         = $request->request->get('category_id');
        $title              = $request->request->get('title');
        $description        = $request->request->get('description');
        $messageContent     = $request->request->get('message');
    }

4. 使用 ValidateAny

此方法检查URI和提交的参数。当使用 ValidateAny 时，约束类中定义的配置只能包含约束集合。这里我们使用 topics2。ValidateAny 也可以在控制器体中作为函数使用。目前，ValidateAny将在具有相同名称的情况下合并请求字段和查询字段。

<?php

//...
use RequestValidatorBundle\Custom\TopicsConstraints; //our custom constraints class
use RA\RequestValidatorBundle\Annotations\ValidateAny;


class TopicController extends Controller
{
    /**
    * @Get("/", name="get_all_topics")
    * @ValidateAny( configuration="topics2", constraintsClass=TopicsConstraints::class)
    * Get a table of all the topics
    */
    public function getAllAction(Request $request){
        $categoryId     = $request->get('category_id');
        //...
    }

    /**
    * @Post("/", name="create_topic")
    * @ValidateAny( configuration="topics2", constraintsClass=TopicsConstraints::class)
    * Get a table of all the topics
    */
    public function createAction(Request $request){
        $categoryId         = $request->request->get('category_id');
        $title              = $request->request->get('title');
        $description        = $request->request->get('description');
        $messageContent     = $request->request->get('message');
        //...
    }
