获取页面内容的正确方法

import requests
from bs4 import BeautifulSoup

url = 'https://example.com'
response = requests.get(url)
soup = BeautifulSoup(response.content, 'html.parser')

# 获取页面内容
content = soup.prettify()
print(content)

const url = 'https://example.com';

fetch(url)
  .then(response => response.text())
  .then(html => {
    const parser = new DOMParser();
    const doc = parser.parseFromString(html, 'text/html');

    // 获取页面内容
    const content = doc.documentElement.outerHTML;
    console.log(content);
  });

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

public class Main {
  public static void main(String[] args) throws Exception {
    String url = "https://example.com";
    HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
    connection.setRequestMethod("GET");
    connection.connect();

    try (BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
      String line;
      StringBuilder content = new StringBuilder();
      while ((line = reader.readLine()) != null) {
        content.append(line);
      }

      // 获取页面内容
      Document doc = Jsoup.parse(content.toString());
      System.out.println(doc.toString());
    }
  }
}
