如何捕获导致异常的值
[英]How to catch value that caused exception
问题描述
Is there any way to catch the value of what caused an exception to be thrown?
有什么方法可以捕获导致抛出异常的值？ I'm currently using a Nest global exception filter that catches just about everything (a very basic one, identical to the one on Nest's documentation) and to show custom messages, I'm doing something like:我目前正在使用一个 Nest 全局异常过滤器，它几乎可以捕获所有内容（一个非常基本的异常过滤器，与 Nest 文档中的那个相同）并显示自定义消息，我正在执行以下操作：
catch(exception, host) {
if(exception instanceof AnyErrorObjectHere) {
// log a custom message
}
}
What if I want to know what caused that issue?如果我想知道是什么导致了这个问题怎么办？ If I tried to send an invalid value to my ORM or if I tried to parse something not parsable... Do my exception holds that value?如果我试图向我的 ORM 发送无效值，或者如果我试图解析不可解析的东西......我的异常是否保持该值？
