os.networkInterfaces()

• 返回：<Object>

  ¥Returns: <Object>

返回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。关联的值是每个对象描述一个分配的网络地址的对象数组。

¥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

  ¥address <string> The assigned IPv4 or IPv6 address

• netmask <string> IPv4 或 IPv6 网络掩码

  ¥netmask <string> The IPv4 or IPv6 network mask

• family <string> IPv4 或 IPv6

  ¥family <string> Either IPv4 or IPv6

• mac <string> 网络接口的 MAC 地址

  ¥mac <string> The MAC address of the network interface

• internal <boolean> true 如果网络接口是环回接口或不可远程访问的类似接口；否则 false

  ¥internal <boolean> true if the network interface is a loopback or similar interface that is not remotely accessible; otherwise false

• scopeid <number> 数字的 IPv6 范围 ID（仅在 family 为 IPv6 时指定）

  ¥scopeid <number> The numeric IPv6 scope ID (only specified when family is IPv6)

• cidr <string> 使用 CIDR 表示法的路由前缀分配的 IPv4 或 IPv6 地址。如果 netmask 无效，则此属性设置为 null。

  ¥cidr <string> The assigned IPv4 or IPv6 address with the routing prefix in CIDR notation. If the netmask is invalid, this property is set to null.
