BeautifulSoup find()返回none

Question

import requests
from bs4 import BeautifulSoup

URL = 'https://www.amazon.de/BenQ-GL2580H-Monitor-Eye-Care-Reaktionszeit/dp/B073NTJHYY/ref=sr_1_3?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=bildschirm&qid=1597391122&sr=8-3'


headers = {
    "User-Agent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.79 Safari/537.36'
}

page = requests.get(URL, headers=headers)
soup = BeautifulSoup(page.content, 'html.parser')

title = soup.find(id="productTitle")
price = soup.find(id="priceblock_ourprice")

print("Titel:",title,"\n","Preis:",price)

输出始终为: Titel: None Preis: None

我已经检查了前面的步骤，但在到达find功能之前，一切都运行得很好。

我以前从来没有问过问题，所以如果我犯了错误，请原谅我。谢谢你的帮助。

您必须使用不同的parser尝试进行以下更改：

soup = BeautifulSoup(page.content, 'html.parser')

至

soup = BeautifulSoup(page.content, 'lxml')
