用Java编写程序快速获取支付宝个人信息的实用方法

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

public class AlipayInfo {

    public static void main(String[] args) {
        // 设置支付宝开放平台的API地址和应用ID
        String apiUrl = "https://openapi.alipay.com/gateway.do";
        String appId = "your_app_id";

        // 构造请求URL
        String requestUrl = apiUrl + "?app_id=" + appId + "&method=alipay.user.info.share";
        
        try {
            // 发送HTTP GET请求并获取响应结果
            URL url = new URL(requestUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
            
            // 解析JSON响应结果，并输出个人信息
            String jsonString = response.toString();
            // TODO: 使用JSON解析库解析jsonString获取个人信息
            
            System.out.println(jsonString);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
