Go語言－訊號os.Interrupt和訊號syscall.SIGTERM的應用

執行個體

package mainimport(    "fmt"    "os"    "os/signal"    "sync"    "syscall"    "time")func worker(stop <-chan bool) {    for {        select {            case <-stop:                fmt.Println("exit")                return            default:                fmt.Println("running...")                time.Sleep(3)        }    }}func main() {    stop := make(chan bool)    var wg sync.WaitGroup    for i := 0; i < 3; i++ {        wg.Add(1)        go func(stop <-chan bool) {            defer wg.Done()          worker(stop)        }(stop)    }    waitForSignal()    close(stop)    fmt.Println("stopping all job")    wg.Wait()}func waitForSignal() {    sigs := make(chan os.Signal)    signal.Notify(sigs, os.Interrupt)    signal.Notify(sigs, syscall.SIGTERM)    fmt.Println(<-sigs)}

運行結果

pkill訊號syscall.SIGTERM

    ...    running...    running...    running...    running...    terminated    running...    running...    stopping all job    exit    exit    exit

或者ctrl+c訊號os.Interrupt
