chapters[i].find('a').attrs['title'] AttributeError：'NoneType‘对象没有属性'attrs’
chapters[i].find('a').attrs['title'] AttributeError：'NoneType‘对象没有属性'attrs’
提问于 2022-05-16 09:25:37
伙计们，我试着得到'href‘，因为我想进入他们每个人，下载里面的所有图像，但是当它说没有属性吸引时，我就会遇到问题。

关于评论意见的扩展：
- 考虑切换到
for item in list样式for循环。 - 考虑尝试/除了块来帮助进行故障排除，因为web抓取充满了用于捕捉您脚的坑洞。用于从每个
a/anchor标记中提取title属性的 - 只需直接转到just中，而不需要
- 。

尝试以下方法：
import requests
from bs4 import BeautifulSoup
url = 'https://readmanganato.com/manga-dr980474'
req_main = requests.get(url)
soup_main = BeautifulSoup(req_main.content, 'html.parser')
data = []
for chapter in soup_main.find_all('a',{"class":"chapter-name text-nowrap"}, href=True):
req_sub = requests.get(chapter['href'])
soup_sub = BeautifulSoup(req_sub.content, 'html.parser')
imgs = [img['src'] for img in soup_sub.find_all('img')]
data.append([chapter['title'], chapter['href'], imgs])
for title, href, imgs in data:
print(title, href, imgs)这展示了遍历a标记的一种更简单的方法。href=True确保只返回带有href标记的条目。如果您有title丢失的问题，也可以添加title=True。
然后显示如何获取子页面，并提取每个页面的所有图像列表。您可能希望添加一个循环来获取图像，而不是仅仅获取URL。
这将使前两项输入如下：
