PHP 7.2.9 Released

Yaf_Dispatcher::catchException

(Yaf >=1.0.0)

Yaf_Dispatcher::catchException开启/关闭自动异常捕获功能

说明

public Yaf_Dispatcher Yaf_Dispatcher::catchException ([ bool $flag ] )

当 application.dispatcher.throwException 开启的时候(你也可以通过调用 Yaf_Dispatcher::throwException(TRUE)() 来开启它),Yaf将会抛出异常而不是触发异常发生。

如果开启了 Yaf_Dispatcher::catchException() (可以通过设置application.dispatcher.catchException来开启),并且在你定义了异常处理的controller的情况下,Yaf会将所有未捕获的异常交给Error Controller的Error Action来处理。

范例

Example #1 Yaf_Dispatcher::catchException()example

/* if you defined a ErrorController like following */
<?php
class ErrorController extends Yaf_Controller_Abstract {
     
/** 
      * you can also call to Yaf_Request_Abstract::getException to get the 
      * un-caught exception.
      */
     
public function error($exception) {
        
/* error occurs */
        
switch ($exception->getCode()) {
            case 
YAF_ERR_NOTFOUND_MODULE:
            case 
YAF_ERR_NOTFOUND_CONTROLLER:
            case 
YAF_ERR_NOTFOUND_ACTION:
            case 
YAF_ERR_NOTFOUND_VIEW:
                echo 
404":"$exception->getMessage();
                break;
            default :
                
$message $exception->getMessage();
                echo 
0":"$exception->getMessage();
                break;
        }
     } 
}
?>

以上例程的输出类似于:

/* now if some error occur, assuming access a non-exists controller(or you can throw a exception yourself): */
404:Could not find controller script **/application/controllers/No-exists-controller.php
