Golang如何处理信号

一个处理信号并退出的例子

package main

import (
	"fmt"
	"os"
	"os/signal"
	"syscall"
)

func main() {
	c := make(chan os.Signal)
	signal.Notify(c, syscall.SIGINT, syscall.SIGTERM)
	exit := false
	for !exit {
		select {
		case s := <- c:
			if s == syscall.SIGINT {
				fmt.Println("caught SIGINT")
				exit = true
			} else if s == syscall.SIGTERM {
				fmt.Println("caught SIGTERM")
				exit = true
			} else {
				fmt.Println("caught unexpect signal: ", s)
			}
		}
	}
}
