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:
1
2
3
4
5
|
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)\vendor\yiisoft\yii2\base\Controller.php

/**

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

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,
