到底哪里出现问题了

 

Answer 1

对于中文编码的文本提取，在获得response对象后，注意不是字符串，你需要将.text移动到soup语句，加上r.encoding=r.apparent_encoding，才不会出现乱码。

page_text = requests.get(url=url, headers=headers)

    page_text.encoding=page_text.apparent_encoding

    # 在首页中解析出章节的标题和详情页的uil

    # 1 示例化BeatifulSoup对象，需要将源码数据加载到该对象中

    soup = BeautifulSoup(page_text.text, 'lxml')

后面也作出如此更改，就行了
