我创建了一个简单的类，将它的设置设置为BeautifulSoup，但是每次尝试使用它（项目“ soup”）时，他都会返回错误。
class Settings:
def __init__(self, url):
self.url = url
requests.get(url, headers={'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'}, timeout=15)
html = urlopen(url)
soup = BeautifulSoup(html, 'lxml')
type(soup)
def soup_element(self):
return(self.type(soup))
settings_website_1 = Settings('https://www.auchandirect.pl/auchan-warszawa/pl/search?text=pepsi+cola&callback=true')
print(settings_website_1.soup_element())
如何正确找到元素的类型（汤）？要在这样的语法中使用它？
links = soup.findAll('a')
任何帮助将不胜感激。
编辑：
url = "https://www.auchandirect.pl/auchan-warszawa/pl/search?text=pepsi+cola&callback=true"
r = requests.get(url, headers={'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'}, timeout=15)
html = urlopen(url)
soup = BeautifulSoup(html, 'lxml')
type(soup)
最佳答案
您尚未将soup设为班级成员。
尝试更改以下内容：
在__init__方法中，将soup更改为self.soup
并将soup_element方法更改为：
def soup_element(self):
return self.soup
现在，您可以使用：
WEBSITE = 'https://www.auchandirect.pl/auchan-warszawa/pl/search?' \
'text=pepsi+cola&callback=true'
settings_website = Settings(WEBSITE)
soup_obj = settings_website.soup_element()
print soup_obj.findAll("a")
并获得结果列表：
