python - Web Scraping - 从 Lazada 电子商务平台提取 URL

Question

我目前正在尝试从 Lazada 电子商务平台抓取产品 URL，但是我从网站获取随机链接而不是产品链接。

https://www.lazada.com.my/oldtown-white-coffee/?langFlag=en&q=All-Products&from=wangpu&pageTypeId=2

我的代码如下：

from bs4 import BeautifulSoup, SoupStrainer
import requests

url = "https://www.lazada.com.my/oldtown-white-coffee/?langFlag=en&q=All- 
       Products&from=wangpu&pageTypeId=2"

page = requests.get(url)    
data = page.text
soup = BeautifulSoup(data)


links = soup.find_all('div', {'class': 'c16H9d'})

for link in soup.find_all("a"):
    print(link.get("href"))

我从这段代码中得到的结果（这不是我想要的）：

这是我需要的链接部分，我想列出产品页面中的所有产品 URL。

我希望你们能帮助我，我知道这很简单它似乎不起作用，从昨天开始一直在看这个。

页面是动态的。在 html 源代码中是生成产品 json 格式的脚本。您可以提取它，然后解析 json 对象以打印出 url：

from bs4 import BeautifulSoup, SoupStrainer
import requests
import json

url = "https://www.lazada.com.my/oldtown-white-coffee/?langFlag=en&q=All-Products&from=wangpu&pageTypeId=2"

page = requests.get(url)    
data = page.text
soup = BeautifulSoup(data)


scripts = soup.find_all('script')

jsonObj = None
for script in scripts:
    if 'window.pageData=' in script.text:
        jsonStr = script.text

        jsonStr = jsonStr.split("window.pageData=")[1]
        jsonObj = json.loads(jsonStr)


products = jsonObj['mods']['listItems']

for item in products:
    print (item['productUrl'])

输出：
