urls = []
with open('urls.txt', mode='rt', encoding='utf-8') as f:
    urls = f.readlines()

# 访问目标 URL 列表并另存为 PDF
with sync_playwright() as p:
    browser = p.chromium.launch()
    for i,url in enumerate(urls):
        context = browser.new_context()
        page = context.new_page()
        page.goto(url)
        page.pdf(path=f"{i}.pdf")
