python 图片抓取

1、图片地址为下载地址访问图片地址可直接下载的

　　#!/usr/bin/env python
　　# -*- coding: utf-8 -*-
　　import urllib2
　　import json
　　import requests
　　import os
　　import sys
　　from time import sleep
　　reload(sys)
　　sys.setdefaultencoding("utf-8")
　　def uploadreColorImg():
　　file_recolorJson = "/home/siyin/Downloads/LibraryMD5.json"
　　recolor_url = "basicurl"
　　savePath = "/home/siyin/recolor0621/"
　　with open(file_recolorJson) as f:
　　j = json.loads(f.read())
　　books = j.get("Books")
　　for item in books:
　　count = 0
　　category = item
　　os.mkdir(savePath+category,0775)
　　os.mkdir(savePath + category+"/c", 0775)
　　imglist = books.get(item)
　　for elem in imglist:
　　contents = imglist.get(elem).get("Contents")
　　for ele in contents :
　　count = count + 1
　　art = contents.get("Art")
　　artUrl = recolor_url + art
　　try:
　　print artUrl
　　r_art = requests.get(artUrl)
　　print r_art.status_code
　　if r_art.status_code == 200:
　　with open(savePath+category+"/"+art+".pdf","wb") as output:
　　for chunk in r_art:
　　output.write(chunk)
　　except:
　　sleep(5)
　　continue
　　finally:
　　output.close()
　　print count

　　if __name__ == "__main__":

　　uploadreColorImg()

2、url是图片链接

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import json
import requests
import os
import sys
import time
import urllib
reload(sys)
sys.setdefaultencoding("utf-8")

def getAndSaveImg(urlParam,save_absPath):

urllib.urlretrieve(urlParam,save_absPath)

def uploadColorImg():

file_json = "/home/siyin/colorfy/colorfy_json.json"
color_url = "http://cdn.colorfy.fungames-forfree.com/v2/android/galleries/images/"
savePath = "/home/siyin/colorfy/"
with open(file_json) as f:
j = json.loads(f.read())
galleries = j.get("galleries")
for gallery in galleries:
galleryId = gallery.get("id")
os.mkdir(savePath+galleryId,0775)
volumes = gallery.get("volumes")
if volumes is not None:
for volume in volumes:
volumeId = volume.get("id")
paintings = volume.get("paintings")
for painting in paintings:
img_path = painting.get("img_path")
img_url = color_url + img_path + '.png'
save_absPath = savePath + galleryId + "/" + img_path + '.png'
try:
r_img = requests.get(img_url)
if r_img.status_code == 200:
getAndSaveImg(img_url,save_absPath)
else:
print "error"
except:
time.sleep(5)
continue
print img_path

if __name__ == "__main__":
uploadColorImg()
