美丽汤对现有元素不返回任何值 [英] Beautiful Soup returns None on existing element

问题描述

我正在努力弄清产品的价格.这是我的代码:

I'm trying to scrape the price of a product. Here's my code:

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)

但是我得到以下答复，而不是期望的价格

But I get the following response instead of the desired price

<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/

I have checked that the element exists using Chrome developer tools. URL: https://www.falabella.com/falabella-cl/product/5311682/Smartphone-iPhone-7-PLUS-32GB/5311682/

尝试以下代码.

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

要获取产品名称:

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

输出:

Smartphone iPhone 7 PLUS 32GB

如果您只查找值$ 379.990 ，请打印此内容

If you only looking for the value $ 379.990 the print this

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