for img in x:
    links.append(img['src'])

Answer 1

我建议使用selenium Web 驱动程序来获取所有页面源然后解析它们。

from bs4 import BeautifulSoup
from selenium import webdriver

url = "https://www.pexels.com/search/flower/"

options = webdriver.FirefoxOptions()
options.add_argument('--ignore-certificate-errors')
options.add_argument('--ignore-ssl-errors')
options.headless = True
driver = webdriver.Firefox(executable_path="./geckodriver", options=options)

driver.get(url)
content = driver.page_source
driver.quit()

soup = BeautifulSoup(content, "html.parser")
links = []
x = soup.select('img[src^="https://images.pexels.com/photos"]')
for img in x:
    links.append(img['src'])
for l in links:
    print(l)
