当我尝试使用以下代码了解Sony耳机的标题时，代码的结果是None。
import requests
from bs4 import BeautifulSoup
URL = 'https://www.amazon.com/Sony-Noise-Cancelling-Headphones-
WH1000XM3/dp/B07G4MNFS1/ref=sxin_0_ac_d_rm?ac_md=0-0-c29ueQ%3D%3D-
ac_d_rm&keywords=sony&pd_rd_i=B07G4MNFS1&pd_rd_r=3e6d5325-8ee4-4ba8-a84f-

headers = {"User-Agent":"Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like
Gecko) Chrome/79.0.3945.88 Safari/537.36"}
page = requests.get(URL, headers=headers)
soup = BeautifulSoup(page.content, "html.parser")
soup.prettify()
#print(soup)
title = soup.find_all('span', {'id':'productTitle'})
print(title, len(title))
电流输出为：
[ ] 0
我花了最后两个小时试图用BeautifulSoup来刮这个标题。我尝试抓取页面上的其他元素。没有成功。我尝试将原始内容发送到文件，但由于存在奇怪的字符而中断。
我尝试了艾哈迈德的答案，仍然没有得到。我尝试了一堆我在网上找到的其他解决方案，但仍然没有得到。我一辈子都想不出如何使用BeautifulSoup来刮这个。
我知道你使用硒，所以这里是硒溶液。
