php - 任何异常的自定义错误处理程序

Question

问题是我按照这个主题做所有事情http://www.yiiframework.com/doc/guide/1.1/en/topics.error，但是在我的控制器中我引发异常（ throw new Exception("error"); ） , yii 不要路由到我的自定义错误控制器并使用系统默认值。如何处理此类异常？

Answer 1

你必须使用 Yii 自己的异常类之一：CException,CDbException或CHttpException. 从您提供的链接： http ://www.yiiframework.com/doc/guide/1.1/en/topics.error#raising-exceptions

// if post ID is invalid
throw new CHttpException(404,'The specified post cannot be found.');

Answer 2

如果 mysql 出现异常，请运行您的查询

$insertCommand = $model->getCommandBuilder()->createSqlCommand($sql,$baseParams+$relParams);
try {
        $insertCommand->execute();
} catch(CDbException $e) {
        // Here's a way to get to the error code for the statement in question.
        // These codes are standardized ANSI SQL "SQLSTATE" error codes.
        $sqlErrorCode = $insertCommand->pdoStatement->errorCode();
        // And to get to the class part of it, simple grab the two first characters.
        // The class should be the same regardless of DB vendor, while the rest of the code can differ.
        // For example one particular error was reported by PostgreSQL as 23505 but MySQL only said 23000.
        $sqlErrorCodeClass = substr($sqlErrorCode, 0, 2);
}
