Yii2使用驼峰命名的形式访问控制器(实例讲解)
author:一佰互联 2019-04-25   click:251

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 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
