Java 手机号码归属地查询实现

在Java中实现手机号码归属地查询,通常有以下几种方法：

使用第三方API服务

使用淘宝API

淘宝提供了免费的手机号码归属地查询API：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class PhoneLocationQuery {
    public static String queryLocation(String phoneNumber) {
        try {
            String url = "http://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel=" + phoneNumber;
            HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
            connection.setRequestMethod("GET");
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "GBK"));
            StringBuilder response = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
            // 解析返回的JSON数据
            String result = response.toString();
            String province = result.substring(result.indexOf("province:\"") + 10, result.indexOf("\"", result.indexOf("province:\"") + 10));
            String carrier = result.substring(result.indexOf("carrier:\"") + 9, result.indexOf("\"", result.indexOf("carrier:\"") + 9));
            return province + " " + carrier;
        } catch (Exception e) {
            e.printStackTrace();
            return "查询失败";
        }
    }
    public static void main(String[] args) {
        String phoneNumber = "13812345678";
        System.out.println(queryLocation(phoneNumber));
    }
}

使用聚合数据API

需要先注册获取API key：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class JuhePhoneLocation {
    private static final String API_KEY = "你的API密钥";
    private static final String URL = "http://apis.juhe.cn/mobile/get";
    public static String queryLocation(String phoneNumber) {
        try {
            String url = URL + "?phone=" + phoneNumber + "&key=" + API_KEY;
            HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
            connection.setRequestMethod("GET");
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder response = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
            // 解析JSON响应
            // 这里需要使用JSON解析库如Gson或Jackson
            // 示例代码省略了JSON解析部分
            return "解析后的结果";
        } catch (Exception e) {
            e.printStackTrace();
            return "查询失败";
        }
    }
}

使用本地数据库

使用纯Java实现（内存查找）

import java.io.*;
import java.util.HashMap;
import java.util.Map;
public class LocalPhoneLocation {
    private static Map<String, String> phoneMap = new HashMap<>();
    static {
        // 初始化时加载数据
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                LocalPhoneLocation.class.getResourceAsStream("/phone_location.txt"), "UTF-8"));
            String line;
            while ((line = reader.readLine()) != null) {
                String[] parts = line.split(",");
                if (parts.length >= 2) {
                    phoneMap.put(parts[0], parts[1]);
                }
            }
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public static String queryLocation(String phoneNumber) {
        // 取前7位进行匹配
        String prefix = phoneNumber.substring(0, 7);
        return phoneMap.getOrDefault(prefix, "未知");
    }
    public static void main(String[] args) {
        System.out.println(queryLocation("13812345678"));
    }
}

使用SQLite数据库

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
public class SQLitePhoneLocation {
    private static final String DB_URL = "jdbc:sqlite:phone_location.db";
    public static String queryLocation(String phoneNumber) {
        String prefix = phoneNumber.substring(0, 7);
        String sql = "SELECT province, carrier FROM phone_location WHERE prefix = ?";
        try (Connection conn = DriverManager.getConnection(DB_URL);
             PreparedStatement pstmt = conn.prepareStatement(sql)) {
            pstmt.setString(1, prefix);
            ResultSet rs = pstmt.executeQuery();
            if (rs.next()) {
                return rs.getString("province") + " " + rs.getString("carrier");
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return "未知";
    }
}

使用现成的Java库

使用phone-number-lib

import com.github.stuxuhai.jpinyin.PhoneNumber;
public class PhoneNumberLibExample {
    public static void main(String[] args) {
        String phoneNumber = "13812345678";
        String location = PhoneNumber.getLocation(phoneNumber);
        System.out.println(location);
    }
}

使用commons-lang3中的PhoneNumberUtil

import org.apache.commons.lang3.tuple.Pair;
import com.google.i18n.phonenumbers.PhoneNumberUtil;
import com.google.i18n.phonenumbers.Phonenumber.PhoneNumber;
public class CommonsLangExample {
    public static void main(String[] args) {
        PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
        String phoneNumber = "+8613812345678";
        try {
            PhoneNumber number = phoneUtil.parse(phoneNumber, "CN");
            String regionCode = phoneUtil.getRegionCodeForNumber(number);
            System.out.println("地区代码: " + regionCode);
            // 注意：这个库主要用于电话号码验证，不是专门用于归属地查询
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

注意事项

1. API限制：使用第三方API时要注意调用频率限制和可能的变化
2. 数据准确性：手机号段归属地数据会随时间变化，需要定期更新
3. 性能考虑：本地查询比API查询更快，但需要维护数据
4. 隐私问题：处理用户手机号码时要遵守相关隐私法规

方法各有优缺点，可以根据实际需求选择最适合的方案，对于简单的应用场景，本地查询方案可能更合适；对于需要频繁查询或不想维护数据的场景,API方案更方便。
