使用go语言测试能ping通吗？

在项目中，我们需要知道哪些IP是可用IP，这时候想到了用ICMP（Internet控制报文协议）。可以使用开源库-github.com/sparrc/go-ping来判断是否能ping通。

使用-github.com/sparrc/go-ping开源库判断是否能ping通的代码：

func ServerPing(target string) bool  {        pinger, err := ping.NewPinger(target)        if err != nil {                panic(err)        }        pinger.Count = ICMPCOUNT        pinger.Timeout = time.Duration(PINGTIME*time.Millisecond)        pinger.SetPrivileged(true)        pinger.Run()// blocks until finished        stats := pinger.Statistics()        fmt.Println(stats)        // 有回包，就是说明IP是可用的        if stats.PacketsRecv >= 1 {                return true        }        return false}

这里是通过回包数量来判断的，也可以通过掉包率来判断。同时，该库提供了Statistics结构体，包含了详细的ICMP信息，如下

type Statistics struct {        // PacketsRecv is the number of packets received.        PacketsRecv int        // PacketsSent is the number of packets sent.        PacketsSent int        // PacketLoss is the percentage of packets lost.        PacketLoss float64        // IPAddr is the address of the host being pinged.        IPAddr *net.IPAddr        // Addr is the string address of the host being pinged.        Addr string        // Rtts is all of the round-trip times sent via this pinger.        Rtts []time.Duration        // MinRtt is the minimum round-trip time sent via this pinger.        MinRtt time.Duration        // MaxRtt is the maximum round-trip time sent via this pinger.        MaxRtt time.Duration        // AvgRtt is the average round-trip time sent via this pinger.        AvgRtt time.Duration        // StdDevRtt is the standard deviation of the round-trip times sent via        // this pinger.        StdDevRtt time.Duration}
