python - Beautiful Soup 在现有元素上返回 None

问题描述

我试图刮掉产品的价格。这是我的代码：

from bs4 import BeautifulSoup as soup
import requests

page_url = "https://www.falabella.com/falabella-cl/product/5311682/Smartphone-iPhone-7-PLUS-32GB/5311682/"
headers={
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'
}
uClient = requests.get(page_url, headers=headers)
print(uClient)
page_soup = soup(uClient.content, "html.parser") #requests
test = page_soup.find("p", {"class":"fb-price"})
print(test)

但我得到以下响应而不是期望的价格

<Response [200]>
None

我已经使用 Chrome 开发者工具检查了该元素是否存在。网址：https ://www.falabella.com/falabella-cl/product/5311682/Smartphone-iPhone-7-PLUS-32GB/5311682/

解决方案

如果你去network tab你会得到以下链接，它以 json 格式检索数据。你可以在没有 Selenium 和 Beautifulsoup 的情况下做到这一点

试试下面的代码。

import requests

page_url = "https://www.falabella.com/rest/model/falabella/rest/browse/BrowseActor/fetch-item-details?{%22products%22:[{%22productId%22:%225311634%22},{%22productId%22:%225311597%22},{%22productId%22:%225311505%22},{%22productId%22:%226009874%22},{%22productId%22:%225311494%22},{%22productId%22:%225311510%22},{%22productId%22:%226009845%22},{%22productId%22:%226009871%22},{%22productId%22:%226009868%22},{%22productId%22:%226009774%22},{%22productId%22:%226782957%22},{%22productId%22:%226009783%22},{%22productId%22:%226782958%22},{%22productId%22:%228107608%22},{%22productId%22:%228107640%22},{%22productId%22:%226009875%22},{%22productId%22:%226782967%22},{%22productId%22:%226782922%22}]}"
headers={
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'
}
response=requests.get(page_url, headers=headers)
res=response.json()
for item in res['products'][0]['product']['prices']:
    print(item['symbol'] + item['originalPrice'])

输出：

$ 379.990
$ 569.990

获取产品名称：

print(res['products'][0]['product']['displayName'])

输出：

Smartphone iPhone 7 PLUS 32GB

如果您只寻找value $ 379.990打印此

print(res['products'][0]['product']['prices'][0]['symbol'] +res['products'][0]['product']['prices'][0]['originalPrice'] )
