【问题描述】:
我一直在为这段代码苦苦挣扎:
def MainPageSpider(max_pages):
page = 1
while page <= max_pages:
url = 'url' + str(page)
source_code = requests.get(url)
plain_text = source_code.text
soup = bs(plain_text, 'html.parser')
for link in soup.findAll(attrs={'class':'col4'}):
href = 'url' + link.a['href']
title = link.span.text
PostPageItems(href)
page += 1
def PostPageItems(post_url):
source_code = requests.get(post_url)
plain_text = source_code.text
soup = bs(plain_text, 'html.parser')
for items in soup.findAll(attrs={'class':'container'}):
title2 = items.find('h1', {'class':'title'}).get_text()
print(title2)
MainPageSpider(1)
每次我尝试从“h1”获取文本时都会收到此错误:
Traceback (most recent call last):
File "Xfeed.py", line 33, in <module>
MainPageSpider(1)
File "Xfeed.py", line 17, in MainPageSpider
PostPageItems(href)
File "Xfeed.py", line 27, in PostPageItems
test = title2.get_text()
AttributeError: 'NoneType' object has no attribute 'get_text'
但是当我在没有 'get_text()' 的情况下运行它时,我会得到 'h1' HTML:
<h1 class="title">Title 1</h1>
None
None
None
None
<h1 class="title">Title 2</h1>
None
None
None
None
<h1 class="title">Title 3</h1>
None
None
None
None
我真的不明白为什么在使用title = link.span.text 时会出现此错误,我在获取文本时没有任何问题。
我只想要文字。
【问题讨论】:

如果项目没有
h1条目,那么find将返回None,这就是为什么您会在输出中看到每个h1之间的所有Nones .你需要处理这种情况。
