python3爬取笔趣阁小说

爬虫第一步：确定要爬取的信息
确定要爬取的网站的URL地址：http://www.xbiquge.la/6/6818/

第二步：分析网站信息
爬小说要获取小说章节目录名称和每一章的阅读链接

第三步：编写代码：
本次爬虫练习完整代码，存在缺陷，小说章节过多的话爬虫可能会被封Ip

    }
    # 小说目录URL，改变这个URL就可以下载对应的小说
    url = 'http://www.xbiquge.la/6/6818/'
    html = requests.get(url, headers=headers).content.decode('utf-8')
    return html

    ''' 获取章节名和链接 '''
    pat2 = r"<dd><a href='(.*?)' >(.*?)</a></dd>"
    title_name = re.findall(pat2, html)
    # 小说保存文件名称
