亚马逊价格网络抓取问题与python，请求和bs4

Question

所以我写了一段代码来获取亚马逊上某个产品的信息，并且我已经可以获取价格并设置一个condition.If，价格的条件得到满足，我将使用gmail向myself.The发送一条消息，问题是当我使用代码获取它所说的价格时

'NoneType' object has no attribute 'get_text'

这是我的代码。不是完整的部分，而是只收集有关产品的信息：

url="https://www.amazon.de/Sony-DigitalKamera-Touch-Display-Vollformatsensor-KartenSlots/dp/B07B4L1PQ8/ref=sr_1_3?keywords=sony+a7&qid=1561393494&s=gateway&sr=8-3"
headers={"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 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[0:6])
print(converted_price)
print(title.strip())

Answer 1

我在你抓取的页面中找不到priceblock_ourprice。

from bs4 import BeautifulSoup
import requests

url = "https://www.amazon.de/Sony-DigitalKamera-Touch-Display-Vollformatsensor-KartenSlots/dp/B07B4L1PQ8/ref=sr_1_3?keywords=sony+a7&qid=1561393494&s=gateway&sr=8-3"
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36"}
page = requests.get(url, headers=headers)
soup = BeautifulSoup(page.content, 'html.parser')
title = soup.find('span', {'id': 'productTitle'}).text
print(title.strip())

Answer 2

只需将user-agent更改为Mozilla only并尝试以下代码即可。

url="https://www.amazon.de/Sony-DigitalKamera-Touch-Display-Vollformatsensor-KartenSlots/dp/B07B4L1PQ8/ref=sr_1_3?keywords=sony+a7&qid=1561393494&s=gateway&sr=8-3"
headers={"User-Agent":"Mozilla/5.0"}
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()
price=price.replace(',','')
converted_price=float(price[0:6])
print(converted_price)
print(title.strip())

输出：
