Go exception handling differs from the structure used in other languages

try {} catch (e) {} finally {}

For go exception handling, use defer , panic ,recover

func main() {    defer func() { // 必须要先声明defer,否则不能捕获到panic异常        fmt.Println("c")        if err := recover(); err != nil {            fmt.Println(err) // 这里的err其实就是panic传入的内容,55        }        fmt.Println("d")    }()    test()}func test() {    fmt.Println("a")    panic(55)    fmt.Println("b")    fmt.Println("f")}

Output result: A C-D

Panic throws an exception
