如何向下滚动并单击按钮以连续Web在python中抓取页面

我想剪贴整个页面以获得帐户链接,但问题是:

  1. 我需要多次点击Load more按钮才能获取要删除的完整帐户列表

  2. 偶尔会出现一个弹出窗口,所以我该如何检测它并单击“取消”按钮

如果可能的话,我宁愿只用请求将整个页面抓取。由于我必须单击按钮,因此考虑使用硒。

这是我的代码:

import time
import requests
from bs4 import BeautifulSoup
import lxml
from selenium import webdriver

driver = webdriver.Chrome()
driver.get('https://society6.com/franciscomffonseca/followers')

time.sleep(3)

try: driver.find_element_by_class_name('bx-button').click() #button to remove popup

except: print("no popups")

driver.find_element_by_class_name('loadMore').click #to click load more button

我正在使用一个测试页面,该页面包含1万个关注者,并希望取消其关注者帐户链接。我已经为抓取程序编写了代码,因此只需要查看完整的网页

https://society6.com/franciscomffonseca/followers

为防万一,报废代码:

r2 = requests.get('https://society6.com/franciscomffonseca/followers')
print(r2.status_code)
r2.raise_for_status

soup2 = BeautifulSoup(r2.content, "html.parser")
a2_tags = soup2.find_all(attrs={"class": "user"})

#attrs={"class": "user-list clearfix"}

follow_accounts = []

for a2 in a2_tags:
    follow_accounts.append('https://society6.com'+a2['href'])

print(follow_accounts)
print("number of accounts scrapped: " + str(len(follow_accounts)))

load more按钮的HTML:

<button class="loadMore" onclick="loadMoreFollowers();">Load More</button>

您可以直接向Society6 API发出请求,如下所示:

counter = 1

while True:
    source = requests.get('https://society6.com/api/users/franciscomffonseca/followers?page=%s' % counter).json()
    if source['data']['attributes']['followers']:
        for i in source['data']['attributes']['followers']:
            print(i['card']['link']['href'])
        counter += 1
    else:
        break

这会将相对的href打印为

/wickedhonna
/wiildrose
/williamconnolly
/whiteca1x

如果要使用绝对href,只需替换

print(i['card']['link']['href'])

使用

print("https://society6.com" + i['card']['link']['href'])
