python，requests和bs4的亞馬遜價格網頁抓取問題

Question

因此，我編寫了一段代碼來獲取有關亞馬遜產品的信息，並且使我可以獲取價格並設置條件。如果滿足價格條件，我將使用gmail向自己發送一條消息。問題是當我使用代碼獲取價格時

'NoneType' object has no attribute 'get_text'

這是我的代碼。 不是全部內容，而是僅收集有關產品的信息：

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

在您抓取的頁面中找不到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

只需將用戶代理更改為Mozilla，然后嘗試以下代碼。

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())

輸出：
