private static func getEthernetIPAddress(from interfaces: [String: String]) -> String? { // 常见虚拟以太网接口名（根据适配器型号可能不同） let poeEthernetInterfaces = ["en2", "en3", "en4", "en5", "eth0", "eth1"]

    for interfaceName in poeEthernetInterfaces {
        if let ethernetIP = interfaces[interfaceName], !ethernetIP.isEmpty {
            return ethernetIP
        }
    }
    return nil
}//我们通过该方法去抓取有线网的IP地址，但是有的设备无法抓取到，怎样才能更准确的抓取到有线网络的IP地址

Sadly, I can’t read Chinese, so I’m answering based on a machine translation.

The code you posted assumes that a specific interface type will have a specific interface name. That’s not a valid assumption. BSD interface names are not considered API on Apple platforms.

I have a lot more information about this in the various posts referenced by Extra-ordinary Networking. Please read them through. If you have follow-up questions, I’d be happy to answer them here.
