下载zhihu指定页面的所有图片到当前文件夹

import re
from selenium import webdriver
import time
import urllib.request

driver = webdriver.Chrome("/home/h/Downloads/chromedriver")
driver.maximize_window()

driver.get("https://www.zhihu.com/question/29134042")
i = 0
while i < 10:
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
    time.sleep(2)
    try:
        driver.find_element_by_css_selector("button.QuestionMainAction").click()
        print("page"+str(i))
        time.sleep(1)
    except:
        break
result_raw = driver.page_source
content_list = re.findall("img src=\"(.+?)\" ",str(result_raw))
n = 0
while n<len(content_list):
    i = time.time()
    local = (r"%s.jpg"%(i))
    urllib.request.urlretrieve(content_list[n], local)
    print("编号："+str(i))
    n = n + 1

需要注意的是

driver = webdriver.Chrome("/home/h/Downloads/chromedriver")

中的参数。
需要先到
https://sites.google.com/a/chromium.org/chromedriver/downloads
下载对应版本的chromedriver，解压后添加到路径中即可使用。
