Python使用Selenium批量自动化获取并下载图片的方法

pip install selenium

from selenium import webdriver  
from PIL import Image  
import io

driver = webdriver.Chrome('path/to/chromedriver')  
driver.get('http://example.com')

images = driver.find_elements_by_css_selector('img')

for image in images:  
    image_url = image.get_attribute('src')  
    response = driver.execute_script("return fetch('" + image_url + "');")  
    image_data = response.content  
    image = Image.open(io.BytesIO(image_data))  
    image.save(image_url.split('/')[-1])  # 将图片保存到本地，文件名保持不变

driver.quit()
