go监听ctrl+c 退出程序信号

代码实现

package main

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

func main() {
    
    //TODO 协程执行业务代码
    
    //监听退出序号
    sigs := make(chan os.Signal, 1)
    done := make(chan bool, 1)
    signal.Notify(sigs, syscall.SIGINT, syscall.SIGTERM)
    go func() {
        sig := <-sigs
        log.Println(sig)
        done <- true
    }()
    log.Println("Server Start Awaiting Signal")
    <-done
    log.Println("Exiting")
}
