Golang Exception Handling

This is a created article in which the information may have evolved or changed.

package mainimport ("fmt")type TryTarget func()type CatchTarget func()func TryAndCatch(target TryTarget, catch CatchTarget) {defer func() {if err := recover(); err != nil {catch()}}()target()}func main() {TryAndCatch(func() {panic("抛出异常")}, func() {fmt.Println("异常恢复")})}

Don't talk first, light out the code, about the Golang program exception handling involves three keywords:

1.panic throws an exception, and once an exception is thrown, the function terminates immediately and the next step automatically jumps to the defer statement

Execute recover catch exception in 2.defer statement, get specific information of exception
