php语法结合百度地图api如何获取指定位置的静态地图图片

php语法如何Java程序来访问百度地图API并获取静态地图图片。我们可以使用Java的HTTPURLConnection类来发送HTTP请求并接收响应。下面web建站小编给大家简单介绍一下具体代码示例！

具体实现语法如下：

import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
 
public class BaiduMapAPIExample {
  public static void main(String[] args) {
    String location = "39.988563,116.473176"; // 指定的位置（纬度,经度）
    int width = 400; // 图片宽度
    int height = 300; // 图片高度
    int zoom = 15; // 缩放级别
    String apiKey = "your_api_key"; // 替换成你的API Key
 
    String requestUrl = "http://api.map.baidu.com/staticimage/v2?ak=" + apiKey
        + "&center=" + location + "&width=" + width + "&height=" + height + "&zoom=" + zoom;
 
    try {
      URL url = new URL(requestUrl);
      HttpURLConnection connection = (HttpURLConnection) url.openConnection();
      connection.setRequestMethod("GET");
      connection.setConnectTimeout(5000); // 设置连接超时时间
      connection.setReadTimeout(5000); // 设置读取超时时间
 
      int responseCode = connection.getResponseCode();
      if (responseCode == HttpURLConnection.HTTP_OK) {
        InputStream inputStream = connection.getInputStream();
        FileOutputStream outputStream = new FileOutputStream("map.png"); // 图片保存路径
        byte[] buffer = new byte[1024];
        int len;
        while ((len = inputStream.read(buffer)) != -1) {
          outputStream.write(buffer, 0, len);
        }
        outputStream.close();
        inputStream.close();
        System.out.println("静态地图图片下载完成！");
      } else {
        System.out.println("请求失败：" + responseCode);
      }
      connection.disconnect();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}
