如何修改HttpUrlConnection的标头

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

public static void main(String[] args) throws Exception {
    URL url = new URL("https://api.example.com/data");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod("GET");
    connection.setRequestProperty("User-Agent", "Mozilla/5.0");
    connection.setRequestProperty("Content-Type", "application/json");
    connection.setRequestProperty("Authorization", "Bearer YOUR_ACCESS_TOKEN");
    connection.setRequestProperty("Custom-Header", "custom_value");
    int responseCode = connection.getResponseCode();
    System.out.println("Response Code: " + responseCode);
    BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    String inputLine;
    StringBuffer response = new StringBuffer();
    while ((inputLine = in.readLine()) != null) {
        response.append(inputLine);
    }
    in.close();
    System.out.println(response.toString());
}
