Codeigniter 3自动加载控制器 [英] Codeigniter 3 autoload controller

问题描述

我在codeigniter中使用 REST Server ，使用方法是我所有控制器中的应用程序，我必须在开始时写以下行:

I'm using REST Server in codeigniter, and the way to use is that then in my app in all my controllers I must write this line on start:

require APPPATH . '/libraries/REST_Controller.php';

有人知道如何自动加载此REST_Controller并避免在我的所有控制器中使用此行吗?我不想使用require.

Does anyone know how to autoload this REST_Controller and to avoid this line in all my controllers? I don't want to use require.

预先感谢

推荐答案

您可以通过Codeigniter的自动加载配置来实现.

You can achieve this through Codeigniter's autoload configuration.

编辑位于目录YourProject/application/config/

$autoload['libraries'] = array('REST_Controller');

并且在控制器中，可以通过$this->rest_controller访问此库类.

And in controllers access this library class through $this->rest_controller.

顺便说一句:Rest_Controllers是一个库文件，所以我认为后缀Controller的名称不是很好的名字.

BTW: Rest_Controllers is a library file, so I don't think a name suffixed with Controller is a good name for it.

Edit

通过您的评论，我得到的是您实际上是指所有从REST_Controller扩展的控制器，并且您不想在每个控制器文件的顶部都要求它.

Through your comment I got that you actually mean all of your controllers extended from REST_Controller, and you don't want require it at the top of every controller file.

解决方案:

1. 将REST_Controller.php移至目录YourProject/application/core/.
2. 在YourProject/application/config/config.php行119中将$config['subclass_prefix'] = 'MY_';更改为$config['subclass_prefix'] = 'REST_';

1. Move REST_Controller.php into directory YourProject/application/core/.
2. In YourProject/application/config/config.php line 119 change $config['subclass_prefix'] = 'MY_'; to $config['subclass_prefix'] = 'REST_';

然后Codeigniter将自动加载REST_Controller.

但是subclass_prefix配置具有全局作用，您需要更改REST_Conttoller.php的位置，因此要进行最小的更改，我认为最好的方法是在目录./application/core/中创建MY_Controller类并要求REST_Controller在此新文件的底部.当CI自动加载MY_controller时，也将需要REST_Controller.

But the subclass_prefix config has a global effect, and you need change the location of REST_Conttoller.php, so to make minimal change I think the best way is you create MY_Controller class in directory ./application/core/ and require REST_Controller at bottom of this new file. When CI load MY_controller automatically REST_Controller will be required too.

通知: MY_Controller需要从CI_Controller
