python - Beautifulsoup - 如何打开图片并下载它们

Question

我想从 here 中获取完整尺寸的产品图片

我的想法是:

• 点击图片链接
• 下载图片
• 回去
• 重复n+1张图片

我知道如何打开图像缩略图，但不知道如何获取全尺寸图像。关于如何做到这一点有什么想法吗？

Answer 1

这将为您提供所有图片的 URL:

import urllib2
from bs4 import BeautifulSoup

url = "http://icecat.biz/p/toshiba/pscbxe-01t00een/satellite-pro-notebooks-4051528049077-Satellite+Pro+C8501GR-17732197.html"
html = urllib2.urlopen(url)
soup = BeautifulSoup(html)

imgs = soup.findAll("div", {"class":"thumb-pic"})
for img in imgs:
        print img.a['href'].split("imgurl=")[1]

输出:

http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g1_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g4_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g2_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g5_satellite-pro-c850.jpg
http://www.toshiba.fr/contents/fr_FR/SERIES_DESCRIPTION/images/g3_satellite-pro-c850.jpg

此代码用于下载和保存这些图像:

import os
import urllib
import urllib2
from bs4 import BeautifulSoup

url = "http://icecat.biz/p/toshiba/pscbxe-01t00een/satellite-pro-notebooks-4051528049077-Satellite+Pro+C8501GR-17732197.html"
html = urllib2.urlopen(url)
soup = BeautifulSoup(html)

imgs = soup.findAll("div", {"class":"thumb-pic"})
for img in imgs:
        imgUrl = img.a['href'].split("imgurl=")[1]
        urllib.urlretrieve(imgUrl, os.path.basename(imgUrl))
