高隆：检查恐慌而不从中恢复 [英] Golang: Checking for panic without recovering from it

问题描述

在延迟功能中，我想看看是否恢复调用将产生非零值（不恢复）

In a defer function, I want to see whether a call to recover would yield a non-nil value (without recovering)

可以吗？

推荐答案

确切的事情是不可能的。你可能只是想重新恐慌，基本上就像在其他语言中重新抛出异常;

That exact thing isn't possible. You probably just want to re-panic, basically like re-throwing an exception in other languages;

        defer func() {
             if e := recover(); e != nil {
                 //log and so other stuff
                 panic(e)
             }
          }
