node.js - 在 node.js 上获取客户端的 MAC 地址

Question

有没有办法在 Node.js 上找到客户端的 mac 地址？我一直在搜索它，我找到了 node-sigar 项目，但它没有工作，因为它抛出“找不到模块 ./build/Release/sigar”错误。

Answer 1

Unless your code is running on the same LAN segment as the client, you cannot obtain the MAC address of a client. You'd need to likely shell out to a command line tool or native support to gain addresses on the local LAN segment.

For nodejs: https://npmjs.org/search?q=Arp

If you try to get remote clients' MAC addresses, you'll end up with the address of a router more than likely.

Answer 2

getmac模块将执行此操作。它调用命令行以获取系统的网络配置信息，然后使用正则表达式解析输出以查找 mac 地址。它使用的系统命令是getmac（Windows）或ifconfig（其他平台）。
