golang 检查网络状态是否正常的方法

如下所示：

package main

import (
 "fmt"
 "os/exec"
 "time"
)

func NetWorkStatus() bool {
 cmd := exec.Command("ping", "baidu.com", "-c", "1", "-W", "5")
 fmt.Println("NetWorkStatus Start:", time.Now().Unix())
 err := cmd.Run()
 fmt.Println("NetWorkStatus End :", time.Now().Unix())
 if err != nil {
 fmt.Println(err.Error())
 return false
 } else {
 fmt.Println("Net Status , OK")
 }
 return true
}

func main() {
 fmt.Println("Hello ", NetWorkStatus())
}

运行结果：

Start: 1525266343

End: 1525266343

Net Status , OK
Hello, true
