基于 yiisoft/yii2-app-advanced,在 GitHub 上新建仓库 yii2-app-advanced,新建接口应用(实现 RESTful 风格的 Web Service 服务的 API),实现模型分层:数据层、逻辑层,明确公共目录、应用、模块的继承、引用关系 (二)

1、定义与规范:
定义:
(1)数据层:models 用于定义数据相关的自动验证和自动完成和数据存取接口;
(2)逻辑层:logics 用于定义数据相关的业务逻辑;

规范:
(1)/common/models 目录中的模型类文件仅允许Gii工具所生成,为公共的模型数据层;
(2)/common/logics 目录中的模型类文件为业务逻辑相关,继承至 /common/models 数据层,为公共的模型逻辑层;
(3)/common 目录中需要引用模型类文件,仅引用 /common/logics 中的模型类文件,例:

public $modelClass = 'common\logics\User';

(4)/api/models、/backend/models、/frontend/models 目录中的模型类文件为业务逻辑相关(仅与各应用相关),继承至 /common/logics 公共逻辑层;
(5)接口、前端、后端应用目录中需要引用模型类文件,仅引用各自目录下的对应模型类文件,例:

use api\models\User;

(6)/api/modules/v1/models 目录中的模型类文件为业务逻辑相关(仅与模块相关),继承至 /api/models 应用逻辑层;
(7)模块目录中需要引用模型类文件,仅引用各自模块下的对应模型类文件,例:

public $modelClass = 'api\modules\v1\models\User';

2、在common目录中新建logics目录,用于MySQL模型的逻辑层所在目录,如图1

图1

3、复制 \common\models\LoginForm.php、\common\models\User.php 至 \common\logics,如图2

图2

4、在common/models目录中的MySQL模型文件仅为Gii工具所生成,删除 \common\models\LoginForm.php,如图3

图3

5、配置路由,使用美观的 URL ,编辑 \frontend\config\main.php

        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
            ],
        ],

6、国际化的支持,新建目录 \common\messages\en-US\model、\common\messages\zh-CN\model,分别用于模型的数据层的美国英语、中文简体;新建 \common\messages\{language}\app.php、\common\messages\{language}\error.php、\common\messages\{language}\success.php,分别用于应用全局消息、应用错误消息、应用成功消息,如图4

图4


app.php
<?php
return [
];

error.php

<?php
return [
    20000 => 'error',
];

success.php

<?php
return [
    10000 => 'success',
];

7、配置应用程序语言,源语言为美国英语,目标语言为简体中文,当源语言和目标语言相同时,是否强制进行消息翻译,默认为假,设置为真,编辑 \common\config\main.php

    'sourceLanguage' => 'en-US',
    'language' => 'zh-CN',
    'components' => [
        'i18n' => [
            'translations' => [
                '*' => [
                    'class' => 'yii\i18n\PhpMessageSource',
                    'forceTranslation' => true,
                    'basePath'=>'@common/messages',
                    'fileMap' => [
                        'app' => 'app.php',
                        'error' => 'error.php',
                        'success' => 'success.php',
                    ],
                ],
            ],
        ],
        'cache' => [
            'class' => 'yii\caching\FileCache',
        ],
    ],

8、打开网址:http://www.github-shuijingwan-yii2-app-advanced.localhost/gii/model ,选项,命名空间为common\models,此时需支持国际化,覆盖\common\models\User.php,如图5

图5

<?php

namespace common\models;

use Yii;

/**

 * @property int $updated_at
 */class User extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */    public static function tableName()
    {
        return '{{%user}}';
    }

    /**
     * @inheritdoc
     */    public function rules()
    {
        return [
            [['username', 'auth_key', 'password_hash', 'email', 'created_at', 'updated_at'], 'required'],
            [['status', 'created_at', 'updated_at'], 'integer'],
            [['username', 'password_hash', 'password_reset_token', 'email'], 'string', 'max' => 255],
            [['auth_key'], 'string', 'max' => 32],
            [['username'], 'unique'],
            [['email'], 'unique'],
            [['password_reset_token'], 'unique'],
        ];
    }

    /**
     * @inheritdoc
     */    public function attributeLabels()
    {
        return [
            'id' => Yii::t('model/user', 'ID'),
            'username' => Yii::t('model/user', 'Username'),
            'auth_key' => Yii::t('model/user', 'Auth Key'),
            'password_hash' => Yii::t('model/user', 'Password Hash'),
            'password_reset_token' => Yii::t('model/user', 'Password Reset Token'),
            'email' => Yii::t('model/user', 'Email'),
            'status' => Yii::t('model/user', 'Status'),
            'created_at' => Yii::t('model/user', 'Created At'),
            'updated_at' => Yii::t('model/user', 'Updated At'),
        ];
    }
}

9、在common/logics目录中的MySQL模型文件为业务逻辑相关,继承至 \common\models 数据层,打开网址:http://www.github-shuijingwan-yii2-app-advanced.localhost/gii/model ,选项,如图6

图6

10、基于 diff ,编辑 \common\logics\User.php,如图7

11、在common/logics目录中的MySQL模型文件为业务逻辑相关,继承至 \common\models\User 数据层

<?php

namespace common\logics;

        $timestamp = (int) substr($token, strrpos($token, '_') + 1);
        $expire = Yii::$app->params['user.passwordResetTokenExpire'];
        return $timestamp + $expire >= time();
    }

    /**

     */    public function removePasswordResetToken()
    {
        $this->password_reset_token = null;
    }
}

12、新建 \common\messages\en-US\model\user.php,支持目标语言为英语美国时的消息翻译

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang
 * Date: 2018/04/04
 * Time: 10:34
 */
return [
    'ID' => 'ID',
    'Username' => 'Username',
    'Auth Key' => 'Auth Key',
    'Password Hash' => 'Password Hash',
    'Password Reset Token' => 'Password Reset Token',
    'Email' => 'Email',
    'Status' => 'Status',
    'Created At' => 'Created At',
    'Updated At' => 'Updated At',
];

13、新建 \common\messages\zh-CN\model\user.php,支持目标语言为简体中文时的消息翻译

<?php
/**
 * Created by PhpStorm.

    'Password Reset Token' => '密码重置令牌',
    'Email' => '邮箱',
    'Status' => '状态',
    'Created At' => '创建时间',
    'Updated At' => '更新时间',
];

14、新建 \api\models\User.php,在api/models目录中的MySQL模型文件为业务逻辑相关(仅与api相关),继承至 \common\logics\User 逻辑层

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang
 * Date: 2018/04/04

 */
namespace api\models;

class User extends \common\logics\User
{

}

15、复制\api\models\User.php 至 \frontend\models\User.php、\backend\models\User.php,调整为各自的命名空间
\frontend\models\User.php

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang

                $this->addError($attribute, 'Incorrect username or password.');
            }
        }
    }

    /**
     * Logs in a user using the provided username and password.
     *
     * @return bool whether the user is logged in successfully
     */    public function login()
    {
        if ($this->validate()) {
            return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
        }
        
        return false;
    }

    /**
     * Finds user by [[username]]
     *
     * @return User|null
     */    protected function getUser()
    {
        if ($this->_user === null) {
            $this->_user = User::findByUsername($this->username);
        }

        return $this->_user;
    }
}

19、新建 \api\models\LoginForm.php,在api/models目录中的MySQL模型文件为业务逻辑相关(仅与api相关),继承至 \common\logics\LoginForm 逻辑层

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang
 * Date: 2018/04/04

 */
namespace api\models;


class LoginForm extends \common\logics\LoginForm
{

}

20、复制\api\models\LoginForm.php 至 \frontend\models\LoginForm.php、\backend\models\LoginForm.php,调整为各自的命名空间
\frontend\models\LoginForm.php

<?php
/**
 * Created by PhpStorm.

\backend\models\LoginForm.php

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang
 * Date: 2018/04/04
 * Time: 11:10
 */
namespace backend\models;


class LoginForm extends \common\logics\LoginForm
{
