如何在Java中只获取页面的HTML内容？

   public static String fetchHtml(String url) throws IOException {

       HttpURLConnection connection = null;

       BufferedReader reader = null;

       StringBuilder htmlContent = new StringBuilder();

       try {

           URL urlObj = new URL(url);

           connection = (HttpURLConnection) urlObj.openConnection();

           connection.setRequestMethod("GET");

           reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));

           String line;

           while ((line = reader.readLine()) != null) {

               htmlContent.append(line);

           }

       } finally {

           if (reader != null) {

               reader.close();

           }

           if (connection != null) {

               connection.disconnect();

           }

       }

       return htmlContent.toString();

   }

   public static void main(String[] args) {

       try {

           String html = fetchHtml("https://www.example.com");

           System.out.println(html);

       } catch (IOException e) {

           e.printStackTrace();

       }

   }

   public static String fetchHtml(String url) throws IOException {

       Document document = Jsoup.connect(url).get();

       Element body = document.body();

       return body.html();

   }

   public static void main(String[] args) {

       try {

           String html = fetchHtml("https://www.example.com");

           System.out.println(html);

       } catch (IOException e) {

           e.printStackTrace();

       }

   }
