python中selenium爬取图片

使用selenium爬取图片可以分为以下步骤：

1. 安装selenium和webdriver

pip install selenium

下载对应浏览器的webdriver，例如Chrome的webdriver下载地址为：http://chromedriver.chromium.org/downloads

2. 加载网页

from selenium import webdriver

browser = webdriver.Chrome()  # 初始化浏览器
browser.get(url)  # 打开网页

3. 定位图片元素并获取图片链接

img_element = browser.find_element_by_xpath('xpath_of_the_image_element')
img_url = img_element.get_attribute('src')

4. 下载图片

import requests

response = requests.get(img_url, stream=True)
with open('image.jpg', 'wb') as f:
    for chunk in response.iter_content(chunk_size=1024):
        if chunk:
            f.write(chunk)

完整代码如下：

from selenium import webdriver
import requests

url = 'https://www.example.com'
browser = webdriver.Chrome()
browser.get(url)

img_element = browser.find_element_by_xpath('xpath_of_the_image_element')
img_url = img_element.get_attribute('src')

response = requests.get(img_url, stream=True)
with open('image.jpg', 'wb') as f:
    for chunk in response.iter_content(chunk_size=1024):
        if chunk:
            f.write(chunk)

browser.quit()
