Python爬虫入门之爬取小说

最近有朋友在看一本小说，但嫌弃网站广告很烦，让我帮忙写个爬虫爬下来看。xūe微测试了下目标网站，都是些简单的静态页面，大约花10分钟写完脚本开始爬，在这记录一下~

目标网站： link

直接上Python代码：

    resp = requests.get(url)
    print(resp.status_code, chapter)

    if resp.status_code == 200:
        wb_data = resp.content.decode("gbk")

⭐对了，运行之前要装lxml库

pip3 install lxml
