Beispielanalyse von Yii2 unter Verwendung der Camel-Case-Benennung für den Zugriff auf Controller

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：

 }
//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）\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，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：\common\components\zController.php

<?php/**

 * User: Steven
 * Date: 2017/10/26
 * Time: 16:50 */namespace common\components;use \yii\base\Controller;use yii\base\InlineAction;class zController extends Controller   //这里需要继承自\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 === &#39;&#39;) {            $id = $this->defaultAction;
        }        $actionMap = $this->actions();        if (isset($actionMap[$id])) {            return \Yii::createObject($actionMap[$id], [$id, $this]);
        } elseif (preg_match(&#39;/^[a-z0-9\\-_]+$/&#39;, $id) && strpos($id, &#39;--&#39;) === false && trim($id, &#39;-&#39;) === $id) {            $methodName = &#39;action&#39; . str_replace(&#39; &#39;, &#39;&#39;, ucwords(implode(&#39; &#39;, explode(&#39;-&#39;, $id))));            if (method_exists($this, $methodName)) {                $method = new \ReflectionMethod($this, $methodName);                if ($method->isPublic() && $method->getName() === $methodName) {                    return new InlineAction($id, $this, $methodName);
                }
            }
        } else {            $methodName = &#39;action&#39; . $id;            if (method_exists($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

如果使用？  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，
