如何获取在从机上执行的流水线阶段中的Jenkins主IP/主机名？

def jenkinsUrl = env.JENKINS_URL
def jenkinsHost

// 解析Jenkins主机名
if (jenkinsUrl.startsWith("https://")) {
  jenkinsHost = jenkinsUrl.substring(8)
} else if (jenkinsUrl.startsWith("http://")) {
  jenkinsHost = jenkinsUrl.substring(7)
}

// 获取Jenkins主机的IP地址
def jenkinsIp = InetAddress.getByName(jenkinsHost).hostAddress

echo "Jenkins主机名: ${jenkinsHost}"
echo "Jenkins IP地址: ${jenkinsIp}"
