playwright下载

playwright中的下载操作相对于selenium来说更简便一些。在playwright中，可以使用`with page.expect_download() as download_info`来等待下载完成，然后通过`download_info.value`获取下载的相关元素，最后通过`download.path()`获取下载的路径。以下是示例代码：

import time
from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch(headless=False)
    context = browser.new_context(accept_downloads=True)
    page = context.new_page()

    # 执行下载操作
    with page.expect_download() as download_info:
        page.click("button#download-button")
        download = download_info.value
        path = download.path()

    # 打印下载路径
    print(path)

以上代码中，`page.click("button#download-button")`是执行启动下载的操作，`download_info.value`获取到了下载的相关元素，然后赋值给`download`，最后通过`download.path()`获取下载的路径。
