如何使用asp.net MVC项目获取客户端MAC地址

function getMACAddress() {
  var ipAddress = null;
  var macAddress = null;

  // 使用ajax请求后端接口获取MAC地址
  $.ajax({
    url: '/api/getmacaddress',
    type: 'GET',
    async: false,
    success: function(response) {
      ipAddress = response.ipAddress;
      macAddress = response.macAddress;
    }
  });

  return macAddress;
}

using System.Net;
using System.Net.NetworkInformation;
using System.Web.Http;

namespace YourProject.Controllers.Api
{
    public class MacAddressController : ApiController
    {
        [HttpGet]
        public IHttpActionResult GetMacAddress()
        {
            string ipAddress = HttpContext.Current.Request.UserHostAddress;
            string macAddress = GetMacAddress(ipAddress);

            return Ok(new { ipAddress, macAddress });
        }

        private string GetMacAddress(string ipAddress)
        {
            string macAddress = null;

            // 使用IP地址获取网络接口
            NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
            foreach (NetworkInterface networkInterface in networkInterfaces)
            {
                IPInterfaceProperties properties = networkInterface.GetIPProperties();
                foreach (UnicastIPAddressInformation address in properties.UnicastAddresses)
                {
                    if (address.Address.ToString() == ipAddress)
                    {
                        macAddress = networkInterface.GetPhysicalAddress().ToString();
                        break;
                    }
                }
            }

            return macAddress;
        }
    }
}

var macAddress = getMACAddress();
console.log(macAddress);
