基于 yiisoft/yii2-app-advanced，在 GitHub 上新建仓库 yii2-app-advanced，新建远程过程调用应用(实现基于 Hprose 2.0 for PHP 的 RPC 服务端)，在 rpc 目录中实现 页面 的相应 RPC 服务，且在 api 目录中的 API 实现 RPC 客户端 (八) (2)

• 编程笔记

1、在 rpc 目录中实现 页面 的相应 RPC 服务，创建 远程过程调用 HTTP 服务器，新建 /rpc/controllers/ServerController.php

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang
 * Date: 2018/08/01
 * Time: 18:02
 */

namespace rpc/controllers;

use Yii;
use yii/web/Controller;
use Hprose/Yii/Server;

/**
 * 远程过程调用 HTTP 服务器
 *
 * @author Qiang Wang <shuijingwanwq@163.com>
 * @since 1.0
 */
class ServerController extends Controller
{
    public $enableCsrfValidation = false;

    public function beforeAction($action)
    {
        parent::beforeAction($action);
        $server = new Server();
        $server->addMethod($action->actionMethod, $this, $action->controller->id . '_' . $action->id);
        $server->start();
    }
}

2、新建页面模型 /rpc/models/Page.php

<?php

namespace rpc/models;


class Page extends /common/logics/Page
{

}

3、新建页面控制器，/rpc/controllers/PageController.php

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang
 * Date: 2018/08/01
 * Time: 15:01
 */

namespace rpc/controllers;

use Yii;
use rpc/models/Page;

/**
 * Page Controller
 *
 * @author Qiang Wang <shuijingwanwq@163.com>
 * @since 1.0
 */
class PageController extends ServerController
{
    /**
     * 创建页面
     *
     * @param array $data 数据
     *
     * @param string $version 版本号(次版本号与修订号)
     * 格式如下：
     * 2.3
     *
     * @param string $language 区域和语言
     * 格式如下：
     * en-US
     *
     * @return mixed
     */
    public function actionCreate(array $data, string $version = '', string $language = '')
    {
        return $data;
        //echo 1;
        //exit;
        //$fileName = date('Y-m-d-H-i-s', time()) . '-' . microtime(true);
        //file_put_contents('./../runtime/' . $fileName . '.txt', '0');
        //return 1;
    }
}

4、然后在浏览器端打开网址：http://rpc.github-shuijingwan-yii2-app-advanced.localhost/page/create ，看到以下输出：Fa2{u#s11″page_create”}z，符合预期

5、通过工厂方法 create 创建客户端，编辑 /api/rests/page/CreateAction.php

<?php
/**
 * @link http://www.yiiframework.com/
 * @copyright Copyright (c) 2008 Yii Software LLC
 * @license http://www.yiiframework.com/license/
 */

namespace api/rests/page;

use Yii;
use yii/base/Model;
use yii/helpers/Url;
use yii/web/ServerErrorHttpException;
use Hprose/Http/Client;

/**
 * CreateAction implements the API endpoint for creating a new model from the given data.
 *
 * For more details and usage information on CreateAction, see the [guide article on rest controllers](guide:rest-controllers).
 *
 * @author Qiang Wang <shuijingwanwq@163.com>
 * @since 1.0
 */
class CreateAction extends Action
{
    /**
     * @var string the scenario to be assigned to the new model before it is validated and saved.
     */
    public $scenario = Model::SCENARIO_DEFAULT;
    /**
     * @var string the name of the view action. This property is need to create the URL when the model is successfully created.
     */
    public $viewAction = 'view';


    /**
     * Creates a new model.
     * @return /yii/db/ActiveRecordInterface the model newly created
     * @throws ServerErrorHttpException if there is any error when creating the model
     */
    public function run()
    {
        if ($this->checkAccess) {
            call_user_func($this->checkAccess, $this->id);
        }

        $client = Client::create('http://rpc.github-shuijingwan-yii2-app-advanced.localhost/page/create', false);
        $page = $client->page_create([
            'title' => 'title',
            'body' => 'body',
        ]);

        print_r($page);
        exit;

        /* @var $model /yii/db/ActiveRecord */
        $model = new $this->modelClass([
            'scenario' => $this->scenario,
        ]);

        $model->load(Yii::$app->getRequest()->getBodyParams(), '');
        if ($model->save()) {
            $response = Yii::$app->getResponse();
            $response->setStatusCode(201);
            $id = implode(',', array_values($model->getPrimaryKey(true)));
            $response->getHeaders()->set('Location', Url::toRoute([$this->viewAction, 'id' => $id], true));
        } elseif ($model->hasErrors()) {
            $response = Yii::$app->getResponse();
            $response->setStatusCode(422, 'Data Validation Failed.');
            foreach ($model->getFirstErrors() as $message) {
                $firstErrors = $message;
                break;
            }
            return ['code' => 20004, 'message' => Yii::t('error', Yii::t('error', Yii::t('error', '20004'), ['firstErrors' => $firstErrors]))];
        } elseif (!$model->hasErrors()) {
            throw new ServerErrorHttpException('Failed to create the object for unknown reason.');
        }

        return ['code' => 10000, 'message' => Yii::t('success', '10805'), 'data' => $model];
    }
}

6、在 Postman 中 POST http://api.github-shuijingwan-yii2-app-advanced.localhost/v1/pages ，响应失败

7、出现以上原因是因为 Windows 下 nginx php 环境，不支持并发的原因，当同时访问多个域名，并且同时指向你本地服务的时候，就不支持并发了。nginx.conf 里面 对不同 server 修改 fastcgi_pass 的端口号，启动多个 php-cgi。如图1

8、在 Postman 中 POST http://api.github-shuijingwan-yii2-app-a-client.localhost/v1/pages ，响应成功

Array
(
    [title] => title
    [body] => body
)

9、新建模块 v1，基于模块实现版本控制，打开：http://www.github-shuijingwan-yii2-app-advanced.localhost/gii/module ，生成模块 v1，如图2

新建模块 v1，基于模块实现版本控制，打开：http://www.github-shuijingwan-yii2-app-advanced.localhost/gii/module ，生成模块 v1

图2

10、重命名 /rpc/modules/v1/controllers/DefaultController.php 为 /rpc/modules/v1/controllers/PageController.php

<?php

namespace rpc/modules/v1/controllers;

/**
 * Page controller for the `v1` module
 */
class PageController extends /rpc/controllers/PageController
{
    public $modelClass = 'rpc/modules/v1/models/Page';
}

11、删除 /rpc/modules/v1/views

12、复制 /api/models/Page.php、/api/models/PageQuery.php、/api/models/PageSearch.php 为 /rpc/models/Page.php、/rpc/models/PageQuery.php、/rpc/models/PageSearch.php，调整命名空间

13、复制 /api/modules/v1/models/Page.php、/api/modules/v1/models/PageQuery.php、/api/modules/v1/models/PageSearch.php 为 /rpc/modules/v1/models/Page.php、/rpc/modules/v1/models/PageQuery.php、/rpc/modules/v1/models/PageSearch.php，调整命名空间

14、编辑 /rpc/config/main.php，将模块加入到应用主体配置的 modules 属性的列表中

    'modules' => [
        'v1' => [
            'class' => rpc/modules/v1/Module::class,
        ],
    ],

15、在浏览器端打开网址：http://rpc.github-shuijingwan-yii2-app-advanced.localhost/v1/page/create ，看到以下输出：Fa2{u#s11″page_create”}z，符合预期

16、通过工厂方法 create 创建客户端，编辑 /api/rests/page/CreateAction.php，调整 HTTP 服务地址

        $client = Client::create('http://rpc.github-shuijingwan-yii2-app-advanced.localhost/v1/page/create', false);
        $page = $client->page_create([
            'title' => 'title',
            'body' => 'body',
        ]);

        print_r($page);
        exit;

17、在 Postman 中 POST http://api.github-shuijingwan-yii2-app-advanced.localhost/v1/pages ，响应正常

Array
(
    [title] => title
    [body] => body
)

18、编辑 /environments/dev/common/config/params-local.php、/environments/prod/common/config/params-local.php

<?php
return [
    // RPC HTTP 服务地址
    'rpc' => [
        'hostInfo' => 'http://rpc.github-shuijingwan-yii2-app-advanced.localhost', // HOME URL
        'baseUrl' => '/v1', // BASE URL
    ],
];

19、新建 RPC 客户端的基础类，/common/logics/rpc/Model.php

<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2018/08/02
 * Time: 13:12
 */

namespace common/logics/rpc;

use Yii;
use Hprose/Http/Client;

/**

 * @since 1.0
 */
class Model extends /yii/base/Model
{
    /**
     * 创建一个同步的 HTTP 客户端
     *
     * @param string $controllerId 控制器ID
     * 格式如下：
     * page
     *
     * @param string $actionId 方法ID
     * 格式如下：
     * create
     *
     * @return object $client 同步的 HTTP 客户端
     */
    public static function client($controllerId, $actionId)
    {
        $url = Yii::$app->params['rpc']['hostInfo'] . Yii::$app->params['rpc']['baseUrl'];
        $client = Client::create($url . '/' . $controllerId . '/' . $actionId, false);
        return $client->$controllerId;
    }
}

20、新建页面模型的公共逻辑类，/common/logics/rpc/Page.php，定义模型属性、场景(块赋值)、验证规则(初步验证请求数据，以避免明显不符合规则的数据，穿透至 RPC 服务端)

<?php

namespace common/logics/rpc;

use Yii;

/**
 * 页面模型
 */
class Page extends Model
{
    const STATUS_DELETED = -1; //状态：删除
    const STATUS_DISABLED = 0; //状态：禁用
    const STATUS_DRAFT = 1; //状态：草稿
    const STATUS_PUBLISHED = 2; //状态：发布

    const CONTROLLER_ID = 'page'; //控制器ID

    const SCENARIO_CREATE = 'create';

    public $slug;
    public $title;
    public $body;
    public $view;
    public $status;

    /**
     * {@inheritdoc}
     */
    public function scenarios()
    {
        $scenarios = parent::scenarios();
        $scenarios[self::SCENARIO_CREATE] = ['slug', 'title', 'body', 'view', 'status'];

        return $scenarios;
    }

    /**
     * {@inheritdoc}
     */
    public function rules()
    {
        return [
            [['title', 'body'], 'required'],
            [['body'], 'string'],
            [['view', 'status'], 'integer'],
            [['slug', 'title'], 'string', 'max' => 255],
        ];
    }

    /**
     * {@inheritdoc}
     */
    public function attributeLabels()
    {
        return [
            'slug' => Yii::t('model/rpc/page', 'Slug'),
            'title' => Yii::t('model/rpc/page', 'Title'),
            'body' => Yii::t('model/rpc/page', 'Body'),
            'view' => Yii::t('model/rpc/page', 'View'),
            'status' => Yii::t('model/rpc/page', 'Status'),
        ];
    }

    /**
     * 创建页面
     *
     * @param array $data 数据
     *
     * @param string $version 版本号(次版本号与修订号)

     * 2.3
     *
     * @param string $language 区域和语言
     * 格式如下：

     *
     * @return array
     */
    public function create(array $data, string $version, string $language)
    {
        $actionId = 'create';
        return self::client(self::CONTROLLER_ID, $actionId)->$actionId($data, $version, $language);
    }

}

21、新建 /api/models/rpc/Page.php

<?php

namespace api/models/rpc;

class Page extends /common/logics/rpc/Page
{

}

22、新建 /api/modules/v1/models/rpc/Page.php

<?php
/**
 * Created by PhpStorm.
 * User: WangQiang
 * Date: 2018/08/02
 * Time: 13:04
 */

namespace api/modules/v1/models/rpc;


class Page extends /api/models/rpc/Page
{

}

23、编辑 /api/modules/v1/controllers/PageController.php，指定模型类

<?php

namespace api/modules/v1/controllers;

/**
 * Page controller for the `v1` module
 */
class PageController extends /api/controllers/PageController
{
    public $modelClass = 'api/modules/v1/models/rpc/Page';
}

23、编辑 /common/logics/Page.php，定义场景

<?php

namespace common/logics;

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

class Page extends /common/models/Page
{
    const STATUS_DELETED = -1; //状态：删除
    const STATUS_DISABLED = 0; //状态：禁用
    const STATUS_DRAFT = 1; //状态：草稿
    const STATUS_PUBLISHED = 2; //状态：发布

    const SCENARIO_CREATE = 'create';

    /**
     * @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',
                ]
            ],
            'slug' => [
                'class' => SluggableBehavior::className(),
                'attribute' => 'title',
                'ensureUnique' => true,
                'immutable' => true
            ],
            'softDeleteBehavior' => [
                'class' => SoftDeleteBehavior::className(),
                'softDeleteAttributeValues' => [
                    'status' => self::STATUS_DELETED
                ],
            ],
        ];
    }

    /**
     * {@inheritdoc}
     */
    public function scenarios()
    {
        $scenarios = parent::scenarios();
        $scenarios[self::SCENARIO_CREATE] = ['slug', 'title', 'body', 'view', 'status'];

        return $scenarios;
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        $rules = [
            [['title', 'body'], 'required'],
            [['slug'], 'unique'],
            ['view', 'default', 'value' => 0],
            ['status', 'default', 'value' => self::STATUS_DRAFT],
        ];
        $parentRules = parent::rules();

        unset($parentRules[0]);

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

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

}

24、编辑 /rpc/config/main.php，以支持国际化

        'i18n' => [
            'translations' => [
                'model/*'=> [
                    'class' => 'yii/i18n/PhpMessageSource',
                    'forceTranslation' => true,
                    'basePath'=>'@common/messages',
                    'fileMap'=>[
                    ],
                ],
                '*'=> [
                    'class' => 'yii/i18n/PhpMessageSource',
                    'forceTranslation' => true,
                    'basePath'=>'@rpc/messages',
                    'fileMap'=>[

                ],
            ],
        ],
    ],

25、编辑 /api/rests/page/CreateAction.php

<?php

            throw new ServerErrorHttpException('Failed to create the object for unknown reason.');
        }
    }
}

26、编辑 /rpc/controllers/PageController.php

<?php
/**

 */

namespace rpc/controllers;

27、在 Postman 中 POST http://api.github-shuijingwan-yii2-app-advanced.localhost/v1/pages ，响应失败

{
	"title":"title-20180731-5"
}

注：接口模型验证失败

    "code": 20004,
    "message": "数据验证失败：内容不能为空。"
}

28、在 Postman 中 POST http://api.github-shuijingwan-yii2-app-advanced.localhost/v1/pages ，响应失败
