在下文中一共展示了ListenFD函数的6个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: ServeFd

// ServeFD creates an http.Server and sets it up to serve given a socket activated
// argument.
func ServeFd(addr string, handle http.Handler) error {
	ls, e := systemd.ListenFD(addr)
	if e != nil {
		return e
	}

	chErrors := make(chan error, len(ls))

	// We don't want to start serving on these sockets until the
	// "initserver" job has completed. Otherwise required handlers
	// won't be ready.
	<-activationLock

	// Since ListenFD will return one or more sockets we have
	// to create a go func to spawn off multiple serves
	for i := range ls {
		listener := ls[i]
		go func() {
			httpSrv := http.Server{Handler: handle}
			chErrors <- httpSrv.Serve(listener)
		}()
	}

	for i := 0; i < len(ls); i += 1 {
		err := <-chErrors
		if err != nil {
			return err
		}
	}

	return nil
}
