Bs4 AttributeError：“NoneType”对象没有属性“get_text”

Question

我刚刚开始了一个跟踪亚马逊价格的应用程序项目。根据教程视频，在这一步，当我运行代码时，它必须显示产品的名称和价格，但唯一出现的是下一个错误：AttributeError: 'NoneType' object has no attribute 'get_text'。我已经在其他页面上尝试过，并在这里修改了相同的主题，但没有找到答案。请帮忙 ;（代码本身：import requestsfrom bs4 import BeautifulSoupURL = 'https://www.amazon.es/dp/B07JQRWLXM/ref=nav_signin?pf_rd_r=FJX3CJC8RWFE3NPQJRNP&'headers = {"User-Agent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)  Chrome/86.0.4240.75 Safari/537.36'} page = requests.get(URL, headers=headers) soup = BeautifulSoup(page.content, 'html.parser') title = soup.find(id="productTitle").get_text() price = soup.find(id = "priceblock_ourprice").get_text() converted_price = float(price[0:3]) print(converted_price) print(title.strip())

Answer 1

您的脚本几乎是正确的，只需使用lxml或html5lib解析器而不是html.parser：

import requests

from bs4 import BeautifulSoup

URL = 'https://www.amazon.es/dp/B07JQRWLXM/ref=nav_signin?pf_rd_r=FJX3CJC8RWFE3NPQJRNP&'

headers = {"User-Agent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'}

page = requests.get(URL, headers=headers)

soup = BeautifulSoup(page.content, 'lxml')   # <-- change to 'lxml' or 'html5lib'

title = soup.find(id="productTitle").get_text()

price = soup.find(id = "priceblock_ourprice").get_text()

converted_price = float(price.split()[0].replace(',', '.'))   # <-- change the conversion method

print(converted_price)

print(title.strip())
