利用高德地图API查询实时公交到站信息，Java代码示例如下：
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class BusQuery {
public static void main(String[] args) {
try {
// 准备查询的URL
String key = "你的密钥";
String city = "北京";
String keywords = "天安门";
String url = "https://restapi.amap.com/v3/bus/stopname?key=" + key + "&city=" + city + "&keywords=" + keywords;
// 发送查询请求
HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(5000);
// 获取查询结果
int responseCode = connection.getResponseCode();
if(responseCode == 200) {
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
StringBuilder response = new StringBuilder();
while ((line = reader.readLine()) != null) {
response.append(line);
}
reader.close();
// 输出查询结果
System.out.println(response.toString());
} else {
System.out.println("查询失败");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
