我試圖在搜索詞下從 Elle.com 抓取資料。我注意到當我單擊按鈕時，它會發送一個更新 url 中 &page=2 的請求。但是，下面的代碼只會讓我得到很多重復的條目。我需要幫助找到一種方法來為回圈的每次迭代設定起點（我認為）。有任何想法嗎？
import requests,nltk,pandas as pd
from bs4 import BeautifulSoup as bs
def get_hits(url):
r = requests.get(url)
soup = bs(r.content, 'html')
body = []
for p in soup.find_all('p',{'class':'body-text'}):
sentences = nltk.sent_tokenize(p.text)
result1 = [s for s in sentences if 'kim' in s]
body.append(result1)
result2 = [s for s in sentences if 'kanye' in s]
body.append(result2)
body = [a for a in body if a!=[]]
if body == []:
body.append("no hits")
return body
titles =[]
key_hits = []
urls = []
counter = 1
for i in range(1,10):
url = f'https://www.elle.com/search/?page={i}&q=kanye'
r = requests.get(url)
soup = bs(r.content, 'html')
groups = soup.find_all('div',{'class':'simple-item grid-simple-item'})
for j in range(len(groups)):
urls.append('https://www.elle.com' groups[j].find('a')['href'])
titles.append(groups[j].find('div',{'class':'simple-item-title item-title'}).text)
key_hits.append(get_hits('https://www.elle.com' groups[j].find('a')['href']))
if (counter == 100):
break
counter =1
data = pd.DataFrame({
'Title':titles,
'Body':key_hits,
'Links':urls
})
data.head()
如果有什么我不明白但我可能應該理解的地方，請告訴我。只是一名試圖在這里學習強大工具的營銷研究人員。

要在 sige 上進行分頁，您可以使用其無限滾動 API URL（此示例將列印9*42標題）：
import requests
from bs4 import BeautifulSoup
api_url = "https://www.elle.com/ajax/infiniteload/"
params = {
"id": "search",
"class": "CoreModels\\search\\TagQueryModel",
"viewset": "search",
"trackingId": "search-results",
"trackingLabel": "kanye",
"params": '{"input":"kanye","page_size":"42"}',
"page": "1",
"cachebuster": "undefined",
}
all_titles = set()
for page in range(1, 10):
params["page"] = page
soup = BeautifulSoup(
requests.get(api_url, params=params).content, "html.parser"
)
for title in soup.select(".item-title"):
print(title.text)
all_titles.add(title.text)
print()
print("Unique titles:", len(all_titles)) # <-- 9 * 42 = 378

實際上，加載更多分頁是從 api 呼叫純 html 回應生成的，每個頁面鏈接/url 都是相對 url，并使用 urljoin 方法將其轉換為絕對 url，我在 api_urls 中進行分頁。
代碼：
import requests
from bs4 import BeautifulSoup
from urllib.parse import urljoin
api_urls = ["https://www.elle.com/ajax/infiniteload/?id=search&class=CoreModels\search\TagQueryModel&viewset=search&trackingId=search-results&trackingLabel=kanye¶ms={"input":"kanye","page_size":"42"}&page=" str(x) "&cachebuster=undefined" for x in range(1,4)]
Base_url = "https://store.steampowered.com"
for url in api_urls:
req = requests.get(url)
soup = BeautifulSoup(req.content,"lxml")
cards = soup.select("div.simple-item.grid-simple-item")
for card in cards:
title = card.select_one("div.simple-item-title.item-title")
p = card.select_one("a")
l=p['href']
abs_link=urljoin(Base_url,l)
print("Title:" title.text " Links: " abs_link)
print("-" * 80)
