Yaf_Dispatcher::catchException()
(Yaf >=1.0.0)
开启/关闭自动异常捕获功能
说明
public Yaf_Dispatcher::catchException([bool $flag]): Yaf_Dispatcher
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。
参数
- $flag
bool
返回值
范例
Example #1 Yaf_Dispatcher::catchException()example
/* if you defined a ErrorController like following */ <?php class ErrorController extends Yaf_Controller_Abstract { /** * you can also call to Yaf_Request_Abstract::getException to get the * un-caught exception. */ public function error($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
