os.networkInterfaces()


    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.

      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.

      The properties available on the assigned network address object include:

      • address <string> The assigned IPv4 or IPv6 address
      • netmask <string> The IPv4 or IPv6 network mask
      • family <string> Either IPv4 or IPv6
      • mac <string> The MAC address of the network interface
      • internal <boolean> true if the network interface is a loopback or similar interface that is not remotely accessible; otherwise false
      • scopeid <number> The numeric IPv6 scope ID (only specified when family is IPv6)
      • 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.
