python save image from url -


i got problem when using python save image url either urllib2 request or urllib.urlretrieve. url of image valid. download manually using explorer. however, when use python download image, file cannot opened. use mac os preview view image. thank you!

update:

the code follow

def downloadimage(self):     request = urllib2.request(self.url)     pic = urllib2.urlopen(request)     print "downloading: " + self.url     print self.filename     filepath = localsaveroot + self.catalog  + self.filename + picture.postfix     # urllib.urlretrieve(self.url, filepath)     open(filepath, 'wb') localfile:         localfile.write(pic.read())

the image url want download http://site.meishij.net/r/58/25/3568808/a3568808_142682562777944.jpg

this url valid , can save through browser python code download file cannot opened. preview says "it may damaged or use file format preview doesn't recognize." compare image download python , 1 download manually through browser. size of former 1 several byte smaller. seems file uncompleted, don't know why python cannot download it.

a sample code works me on windows:

with open('pic1.jpg', 'wb') handle:         response = requests.get(pic_url, stream=true)          if not response.ok:             print response          block in response.iter_content(1024):             if not block:                 break              handle.write(block)
