为什么我只能在eBay上抓取前4页的结果？

import requests
import time

# 假设这是你的API密钥和访问令牌
api_key = 'your_api_key'
access_token = 'your_access_token'

# 构造API请求头
headers = {
    'Authorization': f'Bearer {access_token}',
    'Content-Type': 'application/json'
}

# 构造API请求URL
base_url = 'https://api.ebay.com/sell/fulfillment/v1/order'

# 分页参数
page_number = 1
page_size = 100

while True:
    # 构造完整的API请求URL
    url = f'{base_url}?page={page_number}&pageSize={page_size}'
    
    try:
        response = requests.get(url, headers=headers)
        response.raise_for_status()  # 如果响应状态码不是200，会抛出异常
        
        data = response.json()
        
        # 处理数据...
        
        # 检查是否有更多页面
        if not data['hasMore']:
            break
        
        page_number += 1
        time.sleep(1)  # 请求之间加入延迟
    except requests.exceptions.RequestException as e:
        print(f'Error: {e}')
        break
