java - 从 protected 网站导入 Java 中的 URL 图像

Question

我试图从网站导入图片，当您第一次加载该网站时，有某种只允许浏览器进入的重新路由服务器。 我试过这个:

public class TestURLImage {
public static void main(String[] args) throws MalformedURLException, IOException {
    EventQueue.invokeLater(new Runnable() {
        @Override
        public void run() {
            try {
                UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
            } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
            }

            try {
                String path = "https://kissanime.to/Uploads/Etc/12-15-2012/726336142483.jpg";
                System.out.println("Geting Image from " + path);
                System.out.println();    
                URL url = new URL(path);
                BufferedImage image = ImageIO.read(url);
                System.out.println("Loading image into frame...");
                JLabel label = new JLabel(new ImageIcon(image));
                JFrame f = new JFrame();
                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                f.getContentPane().add(label);
                f.pack();
                f.setLocation(200, 200);
                f.setVisible(true);
            } catch (Exception exp) {
                exp.printStackTrace();
            }

        }
    });

}}

但是我得到一个错误:

那么有什么方法可以获取图像吗？ 或者至少是什么问题？

我建议你使用更高级的东西，比如 apache HTTP Client library .您将对所有通信拥有更多控制权。例如，您可以设置一个标准的用户代理来伪造一个正常的请求。
