> ### defer, panic, recover * 在函數中添加多個defer語句, 當函數執行到最后時, 這些defer語句會按照逆序執行 ~~~ package main import "fmt" func main() { A() B() } func A() { defer func() { if err := recover(); err != nil { fmt.Println(err) } }() fmt.Println("Hi A1") panic("A") //recover 會跳過panic之后的所有語句 fmt.Println("Hi A2") } func B() { fmt.Println("Hi B") } ~~~ > ### 相關閱讀 * #### [Defer, Panic, and Recover](https://my.oschina.net/chai2010/blog/119216) * #### [Go的異常處理 defer, panic, recover](http://blog.csdn.net/wuwenxiang91322/article/details/9042503) * [Go 延遲函數 defer 詳解](https://mp.weixin.qq.com/s/5xeAOYi3OoxCEPe-S2RE2Q)
