基于 yiisoft/yii2-app-advanced，实现 RESTful 风格的 Web Service 服务的 API，请求参数为多模型时，数据填充、验证的实现

1、参考网址：https://www.yiiframework.com/doc/guide/2.0/zh-cn/input-multiple-models ，其用于网页表单是合适的，不过 API 应用的请求参数一般并未添加表单名称(尤其是单个模型输入时)，因此，不太合适，例：表名为 article_type，字段名为 code，那么请求参数名为 article_type_code，而不是：ArticleType[‘code’]，网页表单如图1

图1

2、现在模型数量为7个，分别为：qq_tp_app_penguin(企鹅号的第三方服务平台应用的企鹅媒体用户、QqTpAppPenguin)、article_type(文章类型、ArticleType)、article_category(文章分类、ArticleCategory)、qq_article_category_normal(企鹅号的文章类型(文章)的文章分类、QqArticleCategoryNormal)、article(文章、Article)、qq_article_normal(企鹅号的文章类型(文章)的文章、QqArticleNormal)、qq_tp_app_access_token(企鹅号的第三方服务平台应用的访问令牌(Redis)、RedisQqAuthQqTpAppAccessToken)，示例中仅演示前2个模型的填充、验证的实现

3、发布文章类型：标准(普通、图文)的文章至渠道发布 /qq/v1/articles(article/create)，请求参数并未严格遵循(表名_字段名)的规则，因为严格遵循的话，会导致字段名过长，且仍然可能存在不容易区分的问题，需要后续手动转换为对应模型的字段

1、请求参数列表
(1)uuid：必填，企鹅号ID(UUID)
(2)article_type_code：必填，文章类型代码，standard：标准(普通)
(3)article_category_id：必填，文章分类ID
(4)title：必填，标题
(5)author：可选，作者，默认：空字符串
(6)source：必填，来源，xContent：内容库；vms：视频管理系统；cms：内容管理系统；spider：自媒体
(7)source_user_id：必填，来源用户ID
(8)source_article_id：必填，来源文章ID
(9)content：必填，文章内容
(10)cover_pic：必填，文章封面图
(11)cover_type：可选，文章封面类型，1：单图；3：三图，默认：1
(12)tag：可选，文章标签，以英文半角逗号分隔，默认：空字符串
(13)apply：可选，是否申请原创文章，0：否；1：是(需要用户具有发表图文原创文章资格否则无效)，默认：0
(14)original_platform：可选，原创首发平台，申请原创文章时必填，默认：0
(15)original_url：可选，原创首发链接，申请原创文章时当选择平台不是企鹅号时必填，默认：空字符串
(16)original_author：可选，原创首发作者，申请原创文章时当选择平台不是企鹅号时必填，默认：空字符串

2、输入数据验证规则
(1)必填：uuid、article_type_code、article_category_id、title、source、source_user_id、source_article_id、content、cover_pic
(2)默认值('')：author、tag、original_url、original_author
(3)默认值(1)：cover_type
(4)默认值(0)：apply、original_platform
(5)比对：article_type_code 其值必须等于 standard
(6)存在性：uuid 必须存在于企鹅号的第三方服务平台应用的企鹅媒体用户模型中，且其状态为 1：启用

4、新建模型文件：/common/logics/QqArticleStandardCreateParam.php，其作用为设置输入数据验证规则中的前4条与第6条、确保所有参数值为存在的，便于转换为对应模型字段时，无需再次判断其值是否存在

<?php

namespace common/logics;

use Yii;
use yii/base/Model;

/**
 * QqArticleStandardCreateParam
 */
class QqArticleStandardCreateParam extends Model
{
    public $uuid;
    public $article_type_code;
    public $article_category_id;
    public $title;
    public $author;
    public $source;
    public $source_user_id;
    public $source_article_id;
    public $content;
    public $cover_pic;
    public $cover_type;
    public $tag;
    public $apply;
    public $original_platform;
    public $original_url;
    public $original_author;


    /**

    public function rules()
    {
        return [
            [['uuid', 'article_type_code', 'article_category_id', 'title', 'source', 'source_user_id', 'source_article_id', 'content', 'cover_pic'], 'required'],

            ['article_type_code', 'compare', 'compareValue' => ArticleType::CODE_STANDARD],
        ];
    }

    /**
     * {@inheritdoc}
     */
    public function attributeLabels()
    {
        return [
            'uuid' => Yii::t('model/qq-article-standard-create-param', 'Uuid'),
            'article_type_code' => Yii::t('model/qq-article-standard-create-param', 'Article Type Code'),

            'cover_type' => Yii::t('model/qq-article-standard-create-param', 'Cover Type'),

            'original_author' => Yii::t('model/qq-article-standard-create-param', 'Original Author'),
        ];
    }
}

5、对应的语言包文件
/common/messages/en-US/model/qq-article-standard-create-param.php

<?php /** * Created by PhpStorm. * User: WangQiang * Date: 2018/08/31 * Time: 18:17 */ return [ 'Uuid' => 'Uuid',
    'Article Type Code' => 'Article Type Code',
    'Article Category Id' => 'Article Category Id',

];

/common/messages/zh-CN/model/qq-article-standard-create-param.php

<?php /** * Created by PhpStorm. * User: WangQiang * Date: 2018/08/31 * Time: 18:26 */ return [ 'Uuid' => '企鹅号ID(UUID)',
    'Article Type Code' => '文章类型代码',
    'Article Category Id' => '文章分类ID',

    'Cover Pic' => '文章封面图',
    'Cover Type' => '文章封面类型，1：单图；3：三图',
    'Tag' => '文章标签，以英文半角逗号分隔',
    'Category' => '文章分类编号，即企鹅号的文章类型(文章)的文章分类ID',
    'Apply' => '是否申请原创文章，0：否；1：是(需要用户具有发表图文原创文章资格否则无效)',
    'Original Platform' => '原创首发平台，申请原创文章时必填',
    'Original Url' => '原创首发链接，申请原创文章时当选择平台不是企鹅号时必填',
    'Original Author' => '原创首发作者，申请原创文章时当选择平台不是企鹅号时必填',
];

6、在应用的模型目录中，编辑 /qq/models/Article.php，定义场景

<?php

namespace qq/models;

/**
 * This is the model class for table "{{%article}}".
 *
 * @see Article
 */
class Article extends /common/logics/Article
{
    const SCENARIO_STANDARD_CREATE = 'qq_article_standard_create';

    /**
     * {@inheritdoc}
     */
    public function scenarios()
    {
        $scenarios = parent::scenarios();

        return $scenarios;
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        $rules = [
        ];
        $parentRules = parent::rules();

        return ArrayHelper::merge($rules, $parentRules);
    }

    /**
     * {@inheritdoc}
     * @return ArticleQuery the active query used by this AR class.
     */
    public static function find()
    {
        return new ArticleQuery(get_called_class());
    }
}

7、公共目录的模型数据层，qq_tp_app_penguin(企鹅号的第三方服务平台应用的企鹅媒体用户、QqTpAppPenguin)、/common/models/QqTpAppPenguin.php，代码如下

<?php

namespace common/models;

use Yii;

/**

 */
class QqTpAppPenguin extends /yii/db/ActiveRecord
{
    /**
     * {@inheritdoc}
     */
    public static function tableName()
    {
        return '{{%qq_tp_app_penguin}}';
    }

    /**

    public function rules()
    {
        return [

            [['uuid'], 'unique'],
            [['openid'], 'unique'],
        ];
    }

    /**

     */
    public function attributeLabels()
    {
        return [
            'id' => Yii::t('model/qq-tp-app-penguin', 'ID'),
            'uuid' => Yii::t('model/qq-tp-app-penguin', 'Uuid'),

     */
    public static function find()
    {
        return new QqTpAppPenguinQuery(get_called_class());
    }
}

8、公共目录的模型逻辑层，qq_tp_app_penguin(企鹅号的第三方服务平台应用的企鹅媒体用户、QqTpAppPenguin)、/common/logics/QqTpAppPenguin.php，代码如下

<?php

namespace common/logics;

use Yii;
use yii/behaviors/TimestampBehavior;
use yii2tech/ar/softdelete/SoftDeleteBehavior;
use common/behaviors/UUIDBehavior;
use yii/helpers/ArrayHelper;

class QqTpAppPenguin extends /common/models/QqTpAppPenguin
{
    const STATUS_DELETED = -1; //状态：删除
    const STATUS_DISABLED = 0; //状态：禁用
    const STATUS_ENABLED = 1; //状态：启用

    /**
     * @inheritdoc
     */
    public function behaviors()
    {
        return [
            'timestampBehavior' => [
                'class' => TimestampBehavior::className(),
                'attributes' => [
                    self::EVENT_BEFORE_INSERT => ['created_at', 'updated_at'],
                    self::EVENT_BEFORE_UPDATE => 'updated_at',
                    SoftDeleteBehavior::EVENT_BEFORE_SOFT_DELETE => 'updated_at',
                ]
            ],
            'uuid' => [

                ],
            ],
        ];
    }

    /**
     * {@inheritdoc}
     */
    public function scenarios()
    {
        $scenarios = parent::scenarios();

        return $scenarios;
    }

    /**

    public function rules()
    {
        $rules = [

        $parentRules = parent::rules();

        return ArrayHelper::merge($rules, $parentRules);
    }

    /**

     */
    public static function find()
    {
        return new QqTpAppPenguinQuery(get_called_class());
    }

}

9、在应用的模型目录中，qq_tp_app_penguin(企鹅号的第三方服务平台应用的企鹅媒体用户、QqTpAppPenguin)、/qq/models/QqTpAppPenguin.php，定义具体场景的验证规则，代码如下

<?php

 */

namespace qq/models;

use Yii;

use yii/web/ServerErrorHttpException;

/**

 */
class QqTpAppPenguin extends /common/logics/QqTpAppPenguin
{
    /**
     * {@inheritdoc}
     */
    public function scenarios()
    {
        $scenarios = parent::scenarios();
        $scenarios[Article::SCENARIO_STANDARD_CREATE] = ['uuid'];

        return $scenarios;
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        $rules = [
            /* 发布文章类型：标准(普通、图文)的文章 */
            [['uuid'], 'required', 'on' => Article::SCENARIO_STANDARD_CREATE],
            ['uuid', 'exist', 'filter' => ['status' => self::STATUS_ENABLED], 'on' => Article::SCENARIO_STANDARD_CREATE],
            [['qq_tp_app_id', 'openid'], 'required'],
        ];
        $parentRules = parent::rules();
        unset($parentRules[0], $parentRules[4]);

        return ArrayHelper::merge($rules, $parentRules);
    }

    /**
     * {@inheritdoc}
     * @return QqTpAppPenguinQuery the active query used by this AR class.
     */
    public static function find()
    {
        return new QqTpAppPenguinQuery(get_called_class());
    }
}

10、编辑方法文件 /qq/rests/article/CreateAction.php

14、查看日志，其验证过程中的 SQL 语句

	SELECT EXISTS(SELECT * FROM `cpa_qq_tp_app_penguin` WHERE (`cpa_qq_tp_app_penguin`.`uuid`='e88e79faad9011e8a14554ee75d2ebc10') AND (`status`=1))

15、后续其他模型的验证可以沿用 uuid 的验证方案，便可以实现请求参数为多模型时，数据的填充、验证，/qq/rests/article/CreateAction.php 最终的代码
