在 Python 上解析 Epic Games Store 时出现问题

Question

我在解析 python 中的 EpicGames 商店时遇到问题。我想收到有关免费游戏的信息。我正在写代码，但我只得到 []。我在其他网站上测试过，一切正常。我有 Python 3.8.8

from lxml.html import fromstring
import urllib.request

response = urllib.request.urlopen('https://www.epicgames.com/store/pl/').read()
page = fromstring(response)
games = page.xpath('/html/body/div[1]/div/div[4]/main/div/div[3]/div/div/span[4]/div/div/section/div/div[1]/div/div/a/div/div/div[3]/span[1]')
print(games)

Answer 1

也许您想尝试以下代码：

import requests
from pprint import pprint

import lxml.html


if __name__ == '__main__':
    base_url = 'https://www.epicgames.com'

    response = requests.get(base_url + '/store/pl/free-games')
    root = lxml.html.fromstring(response.content)

    results = root.xpath(".//a[contains(@class, 'DiscoverCardLayout__link')]")

    for result in results:
        url = base_url + result.get('href', '')
        title_item = result.xpath(
            ".//span[@data-testid='offer-title-info-title']")
        studio_item = results[0].xpath(
            ".//span[@data-testid='offer-title-info-subtitle']")
        is_free_item = results[0].xpath(
            ".//div[@data-component='PriceLayout']")

        try:

            pprint(
                {
                    'url': url,
                    'title': title_item[0].text,
                    'studio': studio_item[0].text_content(),
                    'is_free': (
                        is_free_item[0].text_content().strip() == 'Bezpłatne')
                }
            )

        except IndexError:
            continue

将其保存在一个文件中，例如 'epic_script.py' 和运行它：python3 epic_script.py.
