【问题描述】：

有没有办法通过 playwright-python 中的 goto 直接转到其下载链接来下载文件？

async with page.expect_download(timeout=420000) as download_info:
        await page.goto(f'https://example.com/gateway/reports/{id}/file')

Download = await download_info.value
await Download.save_as(Download.suggested_filename)

我发现的唯一方法是将 goto 包装在 try-except 块中

from playwright.sync_api import Playwright, sync_playwright, expect

with sync_playwright() as p:
    #We define the browser, the context and the page
    browser = p.chromium.launch(headless=False)
    context = browser.new_context()
    page = browser.new_page()
    with page.expect_download() as download_info:
        #If we navigate without try, it will throw an exception and it will stop our script, so, we wrap it inside a try except block
        try:
            page.goto("https://manueltgomes.com/wp-content/uploads/2021/09/ParseHTMLLInks_1_0_0_1.zip")
        except:
            pass
    download = download_info.value
    download.save_as(f"./{download.suggested_filename}")
    context.close()
    browser.close()

该文件将保存在 main.py 文件的相同路径中
