Yii2使用驼峰命名的形式访问控制器 [ 技术分享 ]
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()
{
//
}
上面的控制器在访问的时候就要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
/**
* 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 $id
* @return null|object|InlineAction
*/
public function createAction($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 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www.test.com/getFullHotelInfo
以上.
