java归因回传示例代码

以下是Java归因回传示例代码：

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

public class AttributionExample {
    public static void main(String[] args) throws Exception {
        String url = "http://tracking.e.qq.com/conv";
        URL obj = new URL(url);
        HttpURLConnection conn = (HttpURLConnection) obj.openConnection();

        // 设置请求方法为POST
        conn.setRequestMethod("POST");

        // 设置请求头部信息
        conn.setRequestProperty("Content-Type", "application/json");

        // 设置请求体参数
        String jsonData = "{ \"actions\": [{ \"outer_action_id\": \"clickid\", \"action_time\": \"上报时间\", \"user_id\": { \"wechat_openid\": \"行为触发用户openid\", \"wechat_app_id\": \"行为触发小程序appid\" }, \"action_type\": \"转化类型\", \"trace\": { \"click_id\": \"clickid\" } }] }";
        conn.setDoOutput(true);
        OutputStream os = conn.getOutputStream();
        os.write(jsonData.getBytes());
        os.flush();
        os.close();

        // 发送请求并获取响应
        int responseCode = conn.getResponseCode();
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String inputLine;
        StringBuilder response = new StringBuilder();
        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        // 打印响应结果
        System.out.println("Response Code: " + responseCode);
        System.out.println("Response Body: " + response.toString());
    }
}
