我正在從亞馬遜進行一些網絡抓取，遇到了這個錯誤（標題中提到）。這是我的代碼：import requestsfrom bs4 import BeautifulSoupimport smtplibURL = '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()

這是因為該頁面是使用 javascript 動態加載的。您可以使用selenium來獲取網站的html代碼，如下所示：
from selenium import webdriver
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=='
driver = webdriver.Chrome()
driver.get(URL)
time.sleep(5)
page = driver.page_source
driver.close()
因此，這是完整的代碼：
from bs4 import BeautifulSoup
from selenium import webdriver
import time
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=='
driver = webdriver.Chrome()
driver.get(URL)
time.sleep(5)
page = driver.page_source
driver.close()
soup = BeautifulSoup(page, 'html5lib')
title = soup.find(id="productTitle")
price = soup.find(id="priceblock_ourprice")
print(soup.find(id="priceblock_ourprice").get_text())
