NoneType 对象没有属性“get_text”——Python

Question

我正在从亚马逊进行一些网络抓取，遇到了这个错误（标题中提到）。

这是我的代码：

import requests

from bs4 import BeautifulSoup

import smtplib

URL = 'https://www.amazon.co.uk/UGREEN-Adapter-Samsung-Oneplus- Blackview/dp/B072V9CNTK/ref=sr_1_2_sspa?keywords=otg+cable&qid=1578610622&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzRzRRUUdaR05RVlRJJmVuY3J5cHRlZElkPUEwNjExNjM4MVI4NVZaTFlYTlhGSCZlbmNyeXB0ZWRBZElkPUEwMjg1MTU0OEhROERWQTBSRFAzJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==' 

headers = {

"User Agent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64 AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 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])

def check_price():

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

    converted_price = float(price[0:3])

    if(converted_price < 7.00):

        send_mail()

这是因为该页面是使用 javascript 动态加载的。您可以使用selenium来获取网站的html代码，如下所示：from selenium import webdriverURL = 'https://www.amazon.co.uk/UGREEN-Adapter-Samsung-Oneplus- Blackview/dp/B072V9CNTK/ref=sr_1_2_sspa?keywords=otg+cable&qid=1578610622&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzRzRRUUdaR05RVlRJJmVuY3J5cHRlZElkPUEwNjExNjM4MVI4NVZaTFlYTlhGSCZlbmNyeXB0ZWRBZElkPUEwMjg1MTU0OEhROERWQTBSRFAzJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ=='driver = webdriver.Chrome()driver.get(URL)time.sleep(5)page = driver.page_sourcedriver.close()因此，这是完整的代码：from bs4 import BeautifulSoupfrom selenium import webdriverimport timeURL = 'https://www.amazon.co.uk/UGREEN-Adapter-Samsung-Oneplus- Blackview/dp/B072V9CNTK/ref=sr_1_2_sspa?keywords=otg+cable&qid=1578610622&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzRzRRUUdaR05RVlRJJmVuY3J5cHRlZElkPUEwNjExNjM4MVI4NVZaTFlYTlhGSCZlbmNyeXB0ZWRBZElkPUEwMjg1MTU0OEhROERWQTBSRFAzJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ=='driver = webdriver.Chrome()driver.get(URL)time.sleep(5)page = driver.page_sourcedriver.close()soup = BeautifulSoup(page, 'html5lib')title = soup.find(id="productTitle")price = soup.find(id="priceblock_ourprice")print(soup.find(id="priceblock_ourprice").get_text())输出：£6.99
