如何使用 Playwright 從網站下載相同 class 名稱中的多個 excel 文件

Question

在這個網站（ https://www.mca.gov.in/content/mca/global/en/data-and-reports/company-llp-info/incorporated-closed-month.html# ）有多個 excel 文件一一具有相同的 class 名稱和不同的值數據。 我使用 playwright click() function 從網站下載了一個 excel 文件。 我不知道如何在下載第一個文件后自動下載第二個文件。

這里的代碼，

import re
import asyncio
import requests
from playwright.async_api import async_playwright

async def main():
    async with async_playwright() as p:
        browser = await p.chromium.launch(headless = False, slow_mo=50)
        page = await browser.new_page()

        web = "https://www.mca.gov.in/content/mca/global/en/data-and-reports/company-llp-info/incorporated-closed-month.html"

        await page.goto(web)

        await page.click('[class="expand-desk"]')

        async with page.expect_download() as download_info:
            await page.click('[class="doc-link download-file"]')

        download = await download_info.value

        print("download_url = ",download)

        new = re.search("(?P<url>https?://[^\s ' ]+)", str(download)).group("url")
        print("New url = ",new)

        Filename = new.rsplit('=')[1]+".xlsx"

        r = requests.get(new, allow_redirects=True)

        open(Filename, 'wb').write(r.content)

        await page.screenshot(path="report.png")

        await page.pause()
        await browser.close()

asyncio.run(main())

你能提出任何關於這些的想法嗎？

Answer 1

首先獲取一個元素，然后獲取所有元素的計數。 直到計數做一個for循環，然后使用第nth元素，一個一個地點擊下載圖標。

downloadButtons = page.locator('img[alt="download-icon"]')
count = downloadButtons.count()
for i in range(count):
    downloadButtons.nth(i).click()

Answer 2

也許這個簡單的例子會幫助你：

for CURRENT_XPATH in ['FIRST_XPATH', 'SECOND_XPATH']:

    with page.expect_download() as download_info:
        page.click(CURRENT_XPATH)

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