使用flutter获取手机连接的wifi路由器的mac地址 [英] Get mac address of the wifi router my phone is connected to, using flutter

问题描述

我一直在尝试获取设备所连接的wifi路由器的mac地址.我正在使用Flutter.

I have been trying to get the the mac address of my wifi router that my device is connected to. I am using Flutter.

我遇到了一些插件，例如 get_ip ， flutter_ip .但是它要么显示未知，要么不支持android，不支持ios，要么什么都不显示.

I have come across few plugins like get_ip, wifi_info_plugin and also flutter_ip. But either it shows unknown, doesn't support android, doesn't support ios or just shows nothing at all.

我想做的是，当连接到一个特定的wifi路由器时，我的应用只能运行.因此，当连接到除我以外的其他wifi路由器时，基本上将禁用该应用程序的某些功能.

What I am trying to do is to make my app run only when connected to one specific wifi router. So basically some features of the app will be disabled when connected to a different wifi router other than mine.

请建议其他任何插件或其他解决方法.

Please suggest any other plugin or any work around.

您可以使用SystemConfiguration.CaptiveNetwork框架从受支持的接口复制当前的网络信息.请注意，您需要允许访问设备的位置，并在应用程序功能中启用热点配置"和访问WiFi信息":

You can use you SystemConfiguration.CaptiveNetwork framework to copy your current network info from the supported interfaces. Note that you would need to allow access your device's location and enable Hotspot Configuration and Access WiFi Information in your app capabilities:

import UIKit
import CoreLocation
import SystemConfiguration.CaptiveNetwork
import NetworkExtension

class ViewController: UIViewController, CLLocationManagerDelegate {
    let locationManager = CLLocationManager()
    var ssid = ""
    var bssid = ""
    
    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if #available(iOS 14.0, *) {
            fetchNetworkInfo()
        } else {
            fetchBSSIDInfo()
        }
        locationManager.stopUpdatingLocation()
    }
    @available(iOS, introduced: 4.1.0, deprecated: 14.0)
    func fetchBSSIDInfo()  {
        if let interfaces = CNCopySupportedInterfaces() as? [CFString]  {
            for interface in interfaces {
                if let currentNetworkInfo = CNCopyCurrentNetworkInfo(interface) as? [CFString: Any]  {
                    ssid = currentNetworkInfo[kCNNetworkInfoKeySSID] as? String ?? ""
                    print("ssid:", ssid)
                    bssid = currentNetworkInfo[kCNNetworkInfoKeyBSSID] as? String ?? ""
                    print("bssid:", bssid)
                    break
                }
            }
        }
    }
    @available(iOS 14.0, *)

            print("signalStrength:", network.signalStrength, "\n")
            
            print("Indicates whether the network is secure")
            print("isSecure:", network.isSecure, "\n")
