我想从Facebook的异常消息中获取错误代码 - 不做一些hacky爆炸/解决方法。我的代码：
try {
// some fb api method
} catch (Exception $e) {
echo $e; // Outputs i.e. "OAuthException: (#200) Cannot send notifications to a user who has not installed the app"
echo $e->getCode(); // Ouputs "0". Expected: "200"
}
我注意到，通过执行var_dump($e)对象确实包含代码 - 但我不知道如何捕获它，因为它受到保护。
仅供参考，这就是$e的样子：

答案 0 :(得分：3)
你也试过这个吗？
$result = $e->getResult(); //which is the 1st method of the class and provide you all response
//so for getting the code only
echo $result['error']['code'];
