如何获取运行node.js的服务器名称？

const serverName = process.env.SERVER_NAME || 'Unknown Server';
console.log(`Server Name: ${serverName}`);

const os = require('os');
const serverName = os.hostname();
console.log(`Server Name: ${serverName}`);

const net = require('net');
const serverName = net.gethostname();
console.log(`Server Name: ${serverName}`);

const os = require('os');

function getServerName() {
  try {
    const serverName = os.hostname();
    return serverName;
  } catch (error) {
    console.error('Failed to get server name:', error);
    return 'Unknown Server';
  }
}

console.log(`Server Name: ${getServerName()}`);
