腾讯位置服务测距java

根据提供的引用内容，我们可以使用腾讯位置服务的Web API来实现测距功能。以下是实现测距的Java代码示例：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class DistanceCalculator {
    public static void main(String[] args) {
        try {
            String origin = "天安门";
            String destination = "故宫";
            String key = "你的密钥"; // 请替换成你的密钥
            String urlString = "https://apis.map.qq.com/ws/distance/v1/?mode=driving&from="
                    + URLEncoder.encode(origin, "UTF-8") + "&to=" + URLEncoder.encode(destination, "UTF-8")
                    + "&key=" + key;
            URL url = new URL(urlString);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setConnectTimeout(5000);
            connection.setReadTimeout(5000);
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder response = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
            connection.disconnect();
            System.out.println(response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
