Yii2使用驼峰命名的形式访问控制器

yii2在使用的时候，访问控制器的时候，如果控制器的名称是驼峰命名法，那访问的url中要改成横线的形式。例如：

public function actionRoomUpdate()
{
//
}
//访问的时候就要www.test.com/room-update这样访问

最近在做某渠道的直连的时候，他们提供的文档上明确指出接口的形式：

刚开始以为YII2中肯定有这样的设置，然后就去google了下，发现都说不行，自己去看了下，果然，框架里面直接是写死的：（源码）vendoryiisoftyii2aseController.php

/**
     * Creates an action based on the given action ID.
     * The method first checks if the action ID has been declared in [[actions()]]. If so,
     * it will use the configuration declared there to create the action object.
     * If not, it will look for a controller method whose name is in the format of `actionXyz`
     * where `Xyz` stands for the action ID. If found, an [[InlineAction]] representing that
     * method will be created and returned.
     * @param string $id the action ID.
     * @return Action the newly created action instance. Null if the ID doesn't resolve into any action.
     */
    public function createAction($id)
    {
        if ($id === '') {
            $id = $this->defaultAction;
        }

        $actionMap = $this->actions();
        if (isset($actionMap[$id])) {
            return Yii::createObject($actionMap[$id], [$id, $this]);
        } elseif (preg_match('/^[a-z0-9\-_]+$/', $id) && strpos($id, '--') === false && trim($id, '-') === $id) {
            $methodName = 'action' . str_replace(' ', '', ucwords(implode(' ', explode('-', $id))));
            if (method_exists($this, $methodName)) {
                $method = new ReflectionMethod($this, $methodName);
                if ($method->isPublic() && $method->getName() === $methodName) {
                    return new InlineAction($id, $this, $methodName);
                }
            }
        }

        return null;
    }

这点有点low，不过问题倒不大，这个代码很容易理解，我们发现，其实如果在这个源码的基础上再加上一个else就可以搞定，但是还是不建议直接改源码。

由于我们的项目用的事yii2的advanced版本，并且里面有多个项目，还要保证其他项目使用正常（也就是个别的控制器才需要使用驼峰命名的方式访问），这也容易：

我们可以写个components处理：commoncomponentszController.php

<?php
/**
 * Created by PhpStorm.
 * User: Steven
 * Date: 2017/10/26
 * Time: 16:50
 */
namespace commoncomponents;
use yiiaseController;
use yiiaseInlineAction;

class zController extends Controller   //这里需要继承自yiiaseController
{
    /**
     * Author:Steven
     * Desc:重写路由，处理访问控制器支持驼峰命名法
     * @param string $id
     * @return null|object|InlineAction
     */
    public function createAction($id)
    {
        if ($id === '') {
            $id = $this->defaultAction;
        }

        $actionMap = $this->actions();
        if (isset($actionMap[$id])) {
            return Yii::createObject($actionMap[$id], [$id, $this]);
        } elseif (preg_match('/^[a-z0-9\-_]+$/', $id) && strpos($id, '--') === false && trim($id, '-') === $id) {
            $methodName = 'action' . str_replace(' ', '', ucwords(implode(' ', explode('-', $id))));
            if (method_exists($this, $methodName)) {
                $method = new ReflectionMethod($this, $methodName);
                if ($method->isPublic() && $method->getName() === $methodName) {
                    return new InlineAction($id, $this, $methodName);
                }
            }
        } else {
            $methodName = 'action' . $id;
            if (method_exists($this, $methodName)) {
                $method = new ReflectionMethod($this, $methodName);
                if ($method->isPublic() && $method->getName() === $methodName) {
                    return new InlineAction($id, $this, $methodName);
                }
            }
        }

        return null;
    }
}

ok ,这就可以支持使用驼峰形式访问了，当然这个的形式很多，也可以写成一个控制器，然后其它控制器继承这个控制器就行了，但是原理是一样的

如何使用？  是需要用驼峰命名形式访问的控制器中，继承下这个zController就可以了，

<?php
/**
 * Created by PhpStorm.
 * User: Steven
 * Date: 2017/10/18
 * Time: 15:57
 */
namespace backendmoduleshotelcontrollers;
use yiifiltersAccessControl;
use yiifiltersContentNegotiator;
use yiiwebResponse;
use commoncomponentszController;

class QunarController extends zController
{
    public $enableCsrfValidation = false;


    public function behaviors()
    {
        $behaviors = parent::behaviors();
        unset($behaviors['authenticator']);
        $behaviors['corsFilter'] = [
            'class' => yiifiltersCors::className(),
            'cors' => [ // restrict access to
                'Access-Control-Request-Method' => ['*'], // Allow only POST and PUT methods
                'Access-Control-Request-Headers' => ['*'], // Allow only headers 'X-Wsse'
                'Access-Control-Allow-Credentials' => true, // Allow OPTIONS caching
                'Access-Control-Max-Age' => 3600, // Allow the X-Pagination-Current-Page header to be exposed to the browser.
                'Access-Control-Expose-Headers' => ['X-Pagination-Current-Page'],
            ],
        ];
        //配置ContentNegotiator支持JSON和XML响应格式
        /*$behaviors['contentNegotiator'] = [
            'class' => ContentNegotiator::className(), 'formats' => [
                'application/xml' => Response::FORMAT_XML
            ]
        ];*/
        $behaviors['access'] = [
            'class' => AccessControl::className(),
            'rules' => [
                [
                    'ips' => ['119.254.26.*', //去哪儿IP访问白名单
                        '127.0.0.1','106.14.56.77','180.168.4.58'  //蜘蛛及本地IP访问白名单
                    ], 'allow' => true,
                ],
            ],
        ];
        return $behaviors;
    }

}

?>

示例：

/**
     * Author:Steven
     * Desc:酒店静态数据接口
     */
    public function actiongetFullHotelInfo()
    {

    }

访问的时候url为www.test.com/getFullHotelInfo

以上.
