Question

我想抓取一个网站。网站每页有10个投诉预览。我编写了此脚本，以获得10个投诉的链接以及每个链接内的一些信息。当我运行脚本时，出现此错误消息“ RecursionError：超出最大递归深度”。有人可以对我说什么问题。先感谢您！！

# Get 10 links for preview of complaints

    Title = TL.text

    # Get main text of complaint
    Tx = html_soup.main.find('div', {'class': 'description'})
    Text = Tx.text
    C_text.append(Text)
    # Get user name and id
    Uname = html_soup.main.find('span', {'class': 'user'})
    User_name = Uname.span.text
    User_id = Uname.attrs['data-memberid']
    U_name.append(User_name)

    # Get view count of complaint
    Vcount = html_soup.main.find('span', {'view-count-detail'})
    View_count = Vcount.text
    C_count.append(View_count)
    # Get reply for complaint
    Rpnm = html_soup.main.find('h4', {'name'})
    Reply_name = Rpnm.next
    R_name.append(Reply_name)
    # Get reply date
    Rpdt = html_soup.main.find('span', {'date-tips'})
    Reply_date = Rpdt.attrs['title']
    R_date.append(Reply_date)
    # Get reply text
    Rptx = html_soup.main.find('p', {'comment-content-msg company-comment-msg'})
    Reply_text = Rptx.text
    R_text.append(Reply_text)


link_list = getLinks('https://www.sikayetvar.com/arcelik')

for i in link_list:
    z = GetData(i)
    print(z)

PS：我的下一步是将所有信息放入数据框

您的GetData()方法调用自身，没有基本情况：这将导致无限递归：

def GetData(data):
    for i in GetData(data):

您也在呼叫response = get(i)，但随后忽略了结果...也许您是想说

def GetData(link):
    i = get(link)
    ...

BeautifulSoup在其中获取链接和信息
