c获取域名和端口

import socket

# 获取本地主机名
hostname = socket.gethostname()
print("Hostname:", hostname)

# 获取本地IP地址
ip_address = socket.gethostbyname(hostname)
print("IP Address:", ip_address)

# 获取指定域名和端口的连接信息
domain = "www.example.com"
port = 80
try:
    server_address = (domain, port)
    print("Server Address:", server_address)
except socket.gaierror as e:
    print("Error resolving domain:", e)

const http = require('http');

// 获取本地主机名
const hostname = require('os').hostname();
console.log("Hostname:", hostname);

// 获取本地IP地址
const networkInterfaces = require('os').networkInterfaces();
let ip_address;
for (const name of Object.keys(networkInterfaces)) {
    for (const iface of networkInterfaces[name]) {

            ip_address = iface.address;
            break;
        }
    }
}
console.log("IP Address:", ip_address);

// 获取指定域名和端口的连接信息
const domain = "www.example.com";

    port: port,
    path: '/',
    method: 'GET'
