使用Python和BeautifulSoup获取Amazon数据时出错

Question

我刚开始使用Python，我有一个奇怪的行为，Python大多数时候都会给我一个错误，有时它会正确地编译我的代码。在

import requests
from bs4 import BeautifulSoup

jblCharge4URL = 'https://www.amazon.de/JBL-Charge-Bluetooth-Lautsprecher-Schwarz-integrierter/dp/B07HGHRYCY/ref=sr_1_2_sspa?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=jbl+charge+4&qid=1562775856&s=gateway&sr=8-2-spons&psc=1'

def get_page(url):
    page = requests.get(url, headers=headers)
    soup = BeautifulSoup(page.content, 'html.parser')
    return soup

def get_product_name(url):
    soup = get_page(url)
    try:
        title = soup.find(id="productTitle").get_text()
        print("SUCCESS")
    except AttributeError:
        print("ERROR")
while(True)
    print(get_product_name(jblCharge4URL))

控制台输出：

提前谢谢

除了使用requests和BeautifulSoup组合之外，还可以使用requests-html包来下载网页并同时解析内容。使用请求html的示例如下：

from requests_html import HTMLSession

url = r"https://www.amazon.de/JBL-Charge-Bluetooth-Lautsprecher-Schwarz-integrierter/dp/B07HGHRYCY/"

req = HTMLSession().get(url)
product_title = req.html.find("#productTitle", first=True)
print(product_title.text)  #JBL Charge 4 Bluetooth-Lautsprecher in Schwarz – Wasserfeste, portable Boombox mit integrierter Powerbank – Mit nur einer Akku-Ladung bis zu 20 Stunden kabellos Musik streamen
