Yii2使用驼峰命名的形式访问控制器(实例讲解)

  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 $id the action ID. * @return Action the newly created action instance. Null if the ID doesnt resolve into any action. */ public function createAction($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 /** * 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 $id * @return nullobjectInlineAction */ public function createAction($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,

   <?php /** * Created by PhpStorm. * User: Steven * Date: 2017/10/18 * Time: 15:57 */ 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]); $behaviors[corsFilter] = [ class => \yii\filters\Cors::className(), cors => [ // restrict access to Access-Control-Request-Method => [*], // Allow only POST and PUT methods Access-Control-Request-Headers => [*], // Allow only headers X-Wsse Access-Control-Allow-Credentials => true, // Allow OPTIONS caching Access-Control-Max-Age => 3600, // Allow the X-Pagination-Current-Page header to be exposed to the browser. Access-Control-Expose-Headers => [X-Pagination-Current-Page], ], ]; //配置ContentNegotiator支持JSON和XML响应格式 /*$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
