如果图像较新,如何从HTTP下载图像？

import requests
import shutil

url = 'https://example.com/image.jpg'
response = requests.get(url, stream=True)

with open('image.jpg', 'wb') as out_file:
    shutil.copyfileobj(response.raw, out_file)

import java.io.BufferedInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URL;

public class DownloadImage {
    public static void main(String[] args) {
        try {
            URL url = new URL("https://example.com/image.jpg");
            InputStream in = new BufferedInputStream(url.openStream());
            OutputStream out = new FileOutputStream("image.jpg");

            for (int i; (i = in.read()) != -1;) {
                out.write(i);
            }
            in.close();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
