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，若是控制器的名称是驼峰命名法，那访问的url中要改为横线的形式。例如：

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

最近在作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：

刚开始觉得YII2中确定有这样的设置，而后就去google了下，发现都说不行，本身去看了下，果真，框架里面直接是写死的：（源码）\vendor\yiisoft\yii2\base\Controller.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，咱们发现，其实若是在这个源码的基础上再加上一个else就能够搞定，可是仍是不建议直接改源码。

因为咱们的项目用的事yii2的advanced版本，而且里面有多个项目，还要保证其余项目使用正常（也就是个别的控制器才须要使用驼峰命名的方式访问），这也容易：

咱们能够写个components处理：\common\components\zController.php

<?php
/**
 * Created by PhpStorm.
 * User: Steven
 * Date: 2017/10/26
 * Time: 16:50
 */
namespace common\components;
use \yii\base\Controller;
use yii\base\InlineAction;

class zController extends Controller   //这里须要继承自\yii\base\Controller
{
    /**
     * 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 ,这就能够支持使用驼峰形式访问了，固然这个的形式不少，也能够写成一个控制器，而后其它控制器继承这个控制器就好了，可是原理是同样的

如何使用？  是须要用驼峰命名形式访问的控制器中，继承下这个zController就能够了，

<?php

namespace backend\modules\hotel\controllers;
use yii\filters\AccessControl;
use yii\filters\ContentNegotiator;
use yii\web\Response;
use common\components\zController;

class QunarController extends zController
{
    public $enableCsrfValidation = false;


    public function behaviors()
    {
        $behaviors = parent::behaviors();
        unset($behaviors['authenticator']);
        $behaviors['corsFilter'] = [
            'class' => \yii\filters\Cors::className(),
            'cors' => [ // restrict access to

        ];

                'application/xml' => Response::FORMAT_XML
            ]
        ];*/
        $behaviors['access'] = [

                    ], '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
