使用BeautifulSoup进行循环，以便按时间戳抓取多个页面

from bs4 import BeautifulSoup
import requests
import time

base_url = "http://example.com/page="

start_date = "2021-01-01"
end_date = "2021-01-31"

start_timestamp = int(time.mktime(time.strptime(start_date, "%Y-%m-%d")))
end_timestamp = int(time.mktime(time.strptime(end_date, "%Y-%m-%d")))

for timestamp in range(start_timestamp, end_timestamp + 86400, 86400):
    url = base_url + str(timestamp)
    response = requests.get(url)
    soup = BeautifulSoup(response.content, "html.parser")
    
    # 在这里进行页面解析和数据提取
    
    time.sleep(1)  # 延迟1秒，避免过快请求
