Question

我必须从ebay.com抓取数据，我的抓取项是：“汽车的标题”，“制造”，“模型”，“变速器”和“价格”，我已经抓取了所有该项目，但在撰写时代码“传输”，向我显示此错误：

Traceback (most recent call last):
  File "C:/Users/Oogway/PycharmProjects/web_scraping1/test.py", line 27, in <module>
    trans_of_car = title_trans.text
AttributeError: 'NoneType' object has no attribute 'text'

它不会刮擦“传输”项目！ * tip：从“ transmission”中删除一些项目，然后显示错误，并在显示错误后将“ transmission”中的两个项目废弃。

代码：

import requests
from bs4 import BeautifulSoup
import re

url = 'https://www.ebay.com/b/Cars-Trucks/6001?_fsrp=0&_sacat=6001&LH_BIN=1&LH_ItemCondition=3000%7C1000%7C2500&rt=nc&_stpos=95125&Model%2520Year=2020%7C2019%7C2018%7C2017%7C2016%7C2015'
res = requests.get(url)
soup = BeautifulSoup(res.text, 'html.parser')

ebay_cars = soup.find_all('li', class_='s-item')
for car_info in ebay_cars:

    title_div = car_info.find('div', class_='s-item__wrapper clearfix')
    title_sub_div = title_div.find('div', class_='s-item__info clearfix')
    title_p = title_sub_div.find('span', class_='s-item__price')
    title_tag = title_sub_div.find('a', class_='s-item__link')
    title_maker = title_sub_div.find('span', class_='s-item__dynamic s- item__dynamicAttributes1')
    title_model = title_sub_div.find('span', class_='s-item__dynamic s-item__dynamicAttributes2')
    title_trans = title_sub_div.find('span', class_='s-item__dynamic s-item__dynamicAttributes3')

    name_of_car = title_tag.text
    price_of_car = title_p.text
    maker_of_car = title_maker.text
    model_of_car = title_model.text
    trans_of_car = title_trans.text

Answer 1

这是因为，此元素在网站中不存在此特定条目，这意味着它是None。只需将语句放在try , except子句中，这会导致此错误，这将有所帮助。

在这种情况下...

try:
  trans_of_car = title_trans.text
except:
  trans_of_car = ''
