os.networkInterfaces()

• 返回：<Object>

返回一个包含已分配网络地址的网络接口的对象。

🌐 Returns an object containing network interfaces that have been assigned a network address.

返回对象上的每个键都标识一个网络接口。相关的值是一个对象数组，每个对象描述一个分配的网络地址。

🌐 Each key on the returned object identifies a network interface. The associated value is an array of objects that each describe an assigned network address.

分配的网络地址对象上可用的属性包括：

🌐 The properties available on the assigned network address object include:

• address <string> 分配的 IPv4 或 IPv6 地址
• netmask <string> IPv4 或 IPv6 网络掩码
• family <string> 要么是 IPv4，要么是 IPv6
• mac <string> 网络接口的MAC地址
• internal <boolean> true 如果网络接口是回环接口或类似无法远程访问的接口；否则为 false
• scopeid <number> 数值 IPv6 范围 ID（仅在 family 为 IPv6 时指定）
• cidr <string> 分配的 IPv4 或 IPv6 地址，带有 CIDR 表示法的路由前缀。如果 netmask 无效，此属性将设置为 null。
