如何通过更改URL中的一个数字来遍历整个API集合

import requests

base_url = "https://example.com/api/items"
page_size = 10  # 每页显示的条目数

for page in range(1, total_pages + 1):  # total_pages 是总页数，需要预先知道或通过API获取
    url = f"{base_url}?page={page}"
    response = requests.get(url)
    
    if response.status_code == 200:
        data = response.json()
        # 处理数据
        print(f"Page {page}: {data}")
    else:
        print(f"Failed to fetch page {page}: {response.status_code}")
        break

initial_response = requests.get(f"{base_url}?page=1")
total_items = initial_response.json().get("total_items")
total_pages = (total_items + page_size - 1) // page_size  # 向上取整

import time

for page in range(1, total_pages + 1):
    url = f"{base_url}?page={page}"
    retries = 3
    while retries > 0:
        try:
            response = requests.get(url, timeout=10)  # 设置超时时间为10秒
            if response.status_code == 200:
                data = response.json()
                print(f"Page {page}: {data}")
                break
            else:
                print(f"Failed to fetch page {page}: {response.status_code}")
                break
        except requests.Timeout:
            retries -= 1
            if retries == 0:
                print(f"Failed to fetch page {page} after multiple retries")
                break
            time.sleep(1)  # 等待1秒后重试
