Question

我需要下载网页上有下载按钮的所有文件，例如此页面：http://a.vmall.com/topic/list/d6aac030f17e49d990b8a1996e872d53，每个应用都有一个下载按钮，要求您点击＆＃34;下载＆＃34;在网站上，然后开始下载

如何编写python或selenium脚本以自动下载具有＆＃34; download＆＃34;的所有文件。按钮？感谢

Answer 1

selenium 在这里没用，只需使用BeautifulSoup来获取链接即可。

例如：

import re
import requests
from bs4 import BeautifulSoup

link = 'http://a.vmall.com/topic/list/d6aac030f17e49d990b8a1996e872d53'

r = requests.get(link)
soup = BeautifulSoup(r.text, "html.parser")

for i in soup.find_all('a', {'class': "app-btn-down"}):
    print(re.search('http://.*\.apk', i.get('href')).group(0))

输出：

http://122.11.38.214/dl/appdl/application/apk/72/723e6026cf0f4a2eb4b7f564f6c82715/com.google.android.wearable.app.cn.1510301352.apk

然后你可以保存链接，或使用其他包如urllib或请求下载它们。

Answer 2

我认为你应该以艰难的方式尝试：

btns = driver.find_elements_by_tag_name("a")
for btn in btns:
    btn.click()
