How to Scrape and Download Novels from Biquw.com Using Python

Preface

Hello, I am a Python enthusiast sharing a practical web‑scraping example.

1. Novel Download

To download any novel from the site, open its page and note the numeric ID in the URL (e.g., 951 ). This ID is used in the script to fetch the book’s contents.

2. Implementation Details

The complete Python code is shown below:

import requests
import os
from bs4 import import BeautifulSoup
import time

def book_page_list(book_id):
    '''
    通过传入的书号bookid，获取此书的所有章节目录
    :param book_id:
    :return: 章节目录及章节地址
    '''
    url = 'http://www.biquw.com/book/{}/'.format(book_id)
    headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.71 Safari/537.36'}
    response = requests.get(url, headers)
    response.encoding = response.apparent_encoding
    response = BeautifulSoup(response.text, 'lxml')
    booklist = response.find('div', class_='book_list').find_all('a')
    return booklist

def book_page_text(bookid, booklist):
    '''
    通过书号、章节目录，抓取每一章的内容并存档
    :param bookid:str
    :param booklist:
    :return:None
    '''
    try:
        for book_page in booklist:
            page_name = book_page.text.replace('*', '')
            page_id = book_page['href']
            time.sleep(3)
            url = 'http://www.biquw.com/book/{}/{}'.format(bookid, page_id)
            headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.71 Safari/537.36'}
            response_book = requests.get(url, headers)
            response_book.encoding = response_book.apparent_encoding
            response_book = BeautifulSoup(response_book.text, 'lxml')
            book_content = response_book.find('div', id="htmlContent")
            with open("./{}/{}.txt".format(bookid, page_name), 'a') as f:
                f.write(book_content.text.replace('\xa0', ''))
                print("当前下载章节：{}".format(page_name))
    except Exception as e:
        print(e)
        print("章节内容获取失败，请确保书号正确，及书本有正常内容。")

if __name__ == '__main__':
    bookid = input("请输入书号(数字)：")
    if not os.path.isdir('./{}'.format(bookid)):
        os.mkdir('./{}'.format(bookid))
    try:
        booklist = book_page_list(bookid)
        print("获取目录成功！")
        time.sleep(5)
        book_page_text(bookid, booklist)
    except Exception as e:
        print(e)
        print("获取目录失败，请确保书号输入正确！")

Run the script, enter the numeric book ID when prompted, and the program will create a folder named after the ID, storing each chapter as a separate text file.

3. Common Issues

Frequent errors occur when the site blocks rapid requests. To avoid anti‑scraping measures, randomize the User‑Agent header or use proxies, and add delays between requests.

4. Conclusion

This article demonstrates how to obtain novel content via a Python web scraper using the requests library and BeautifulSoup selectors, and it also discusses typical anti‑scraping problems and their solutions.
