我在eBay python sdk查找API中遇到问题

Question

我正在尝试一个在智能设备上收集数据的项目。我决定使用eBay python SDK，而不是依赖于网络抓取。我有几个问题

1. 当我请求某个特定商品（例如“ iPhone x 64gb”）时，我得到的响应是eBay列表的清单。在列表中，某些列表项可能以以下形式出现：a）iPhone 6列表，这不是我想要的。 b。）两部手机的清单（例如，iPhone x 64 Gb和256gb版本）。如何过滤烂摊子？

2. python SDK的文档不足，因为我需要更多关于过滤XML响应以及向我的API请求添加搜索过滤器的知识。

3. 我必须多次呼叫同一项目，但要响应发送的另一个页码（最多100页，每页100个项目）。我通常会看到很多相同商品，相同价格的商品，它们的URL指向同一卖家。这可能不会帮助我对指标进行准确的统计分析，例如“ iPhone x”的每日平均销售价格。如何从API获取更好的示例数据，因为我不会获得所有的“ iPhone X”列表？

使用发现API时遇到的所有问题。

from ebaysdk.finding import Connection as find_connect
from statistics import mean, median
from bs4 import BeautifulSoup

APP_ID = 'Removed for privacy reasons'
# keywords = input("Enter search keywords(e.g 'white board'): ")

api = find_connect(appid=APP_ID, config_file=None,  siteid="EBAY-ENCA")
request = {
        'keywords': "Iphone x 64gb",
        'itemFilter': [
            {'name': 'Condition', 'value': 'Used'},
            {'name': 'currency', 'value': 'CAD'},
            {'name': 'minPrice', 'value': 100.0}
        ],
        'paginationInput': {
            'entriesPerPage': 100,
            'pageNumber': 1
        },
    }
response = api.execute('findItemsByKeywords', request)

# print(responses.dict())
soup = BeautifulSoup(response.content, 'lxml')
totalentries = int(soup.find('totalentries').text)
items = soup.find_all('item')

print(f"{totalentries} items found")

print_no = 0
prices = []
print(f"Current list is {len(items)} items long")
for item in items:
    cat = item.categoryname.string.lower()
    title = item.title.string.lower()
    price = int(round(float(item.currentprice.string)))
    url = item.viewitemurl.string.lower()

    print('-'*20)
    print(f"{cat}\n{title}\n{price}\n{url}\n")
    prices.append(price)
    print_no += 1

print(f"{print_no} items have been printed")
print(f"Average price is ${mean(prices)}. Median is ${median(prices)}")

我可以收到诸如以下的输出>

3242 items found
Current list is 100 items long
