android如何获取本机ip地址及ip归属地

# 前言 #

本篇文章主要介绍android如何获取本机ip地址及ip归属地。

# 定义 #

ip地址是指手机在连接到互联网时所获得的唯一网络地址。

ip归属地是指通过ip地址查询器对应的地理位置信息，如省市区等信息。

# 获取ip地址 #

如果只是查看本机ip，不涉及应用开发，可以依次打开手机设置-我的设备-状态信息-ip地址界面进行查看（不同品牌手机型号会有差异）。

下面开发过程中获取本机ip方法：

1.首先是要在清单文件中配置必要的权限：

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

2.手机在不同的网络环境下获取ip的方法：

    //获取ip

    public void getIPAddress(Context context) {

        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo networkInfo = cm.getActiveNetworkInfo();

        if (networkInfo != null && networkInfo.isConnectedOrConnecting()) {

            //网络连接可用，判断网络连接类型

            if (networkInfo.getType() == ConnectivityManager.TYPE_WIFI) {

                //wifi网络

                WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

                WifiInfo wifiInfo = wifiManager.getConnectionInfo();

                int ipAddress = wifiInfo.getIpAddress();

                String ip = String.format("%d.%d.%d.%d",

                        (ipAddress & 0xff),

                        (ipAddress >> 8 & 0xff),

                        (ipAddress >> 16 & 0xff),

                        (ipAddress >> 24 & 0xff));

                Log.e("tag", "ip：" + ip);

            } else if (networkInfo.getType() == ConnectivityManager.TYPE_MOBILE) {

                //移动网络

                getLocalIpAddress();

            }

        } else {

            //没有网络链接

        }

    }

    private void getLocalIpAddress() {

        try {

            ArrayList<NetworkInterface> networkInterfaces = Collections.list(NetworkInterface.getNetworkInterfaces());

            for (NetworkInterface networkInterface : networkInterfaces) {

                ArrayList<InetAddress> inetAddresses = Collections.list(networkInterface.getInetAddresses());

                for (InetAddress address : inetAddresses) {

                    String ip = address.getHostAddress();

                    if (!address.isLoopbackAddress() && (address instanceof Inet4Address)) {

                        Log.e("tag", "ipv4：" + ip);

                    }

                    if (!address.isLoopbackAddress() && (address instanceof Inet6Address)) {

                        Log.e("tag", "ipv6：" + ip);

                    }

                }

            }

        } catch (SocketException socketException) {

            Log.e("tag", socketException.getMessage());

        }

    }

# 获取ip归属地 #

想要获取到ip归属地，一般需要获取到ip地址后通过第三方服务来查询，下面展示一下android使用ip数据云获取ip归属地的具体方法：

  //获取ip归属地

    private Location getIpData(String ip, String key) {

        Location location = null;

        try {

            URL url = new URL("https://api.ipdatacloud.com/v2/query?ip=" + ip + "&key=+" + key);

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();

            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));

            StringBuffer sb = new StringBuffer();

            String line;

            while ((line = in.readLine()) != null) {

                sb.append(line);

            }

            in.close();

            connection.disconnect();

            // 解析返回的JSON数据，获取IP归属地信息

            // 这里需要使用JSON解析库，例如gson、fastjson

            String jsonResult = sb.toString();

            location = new Gson().fromJson(jsonResult, Location.class);

        } catch (Exception e) {

            e.printStackTrace();

        }

        return location;

    }

    class Location {

        private String AreaCode;        //行政区码

        private String City;            //城市

        private String CityCode;        //城市代码

        private String Continent;       //洲

        private String Country;         //国家/地区

        private String CountryCode;     //国家/地区英文简写

        private String District;        //区县

        private String Elevation;       //海拔

        private String Ip;              //ip地址

        private String Isp;             //运营商

        private String Latitude;        //纬度

        private String Longitude;       //经度

        private Street[] MultiStreet;   //历史街道位置

        private String Province;        //省份

        private String Street;          //街道

        private String TimeZone;        //时区

        private String WeatherStation;  //气象站

        private String ZipCode;         //邮编

    }

    class Street {

        private String Lng;             //经度

        private String Lat;             //纬度

        private String Province;        //省份

        private String City;            //城市

        private String District;        //区县

        private String Street;          //街道

        private String Radius;          //范围半径

        private String ZipCode;         //邮政编码

    }
