python 3.3 下载固定链接文件并保存的方法

python 3.3 下载固定链接文件并保存。

import urllib.request
print ("downloading with urllib")
url = 'http://www.wzsky.net/img2013/uploadimg/20130906/1216294.jpg'
f = urllib.request.urlopen(url)
data = f.read()
with open("d:/color/1216294.jpg", "wb") as code:
code.write(data)

urllib在3.3版本有了很大变化：

urllib.error: ContentTooShortError; HTTPError; URLError

urllib.parse: parse_qs; parse_qsl; quote; quote_from_bytes; quote_plus; unquote

unquote_plus; unquote_to_bytes; urldefrag; urlencode; urljoin; urlparse;
urlsplit; urlunparse; urlunsplit

urllib.request: AbstractBasicAuthHandler; AbstractDigestAuthHandler; BaseHandler;

 CatheFTPHandler; FTPHandler; FancyURLopener; FileHandler;
 HTTPBasicAuthHandler; HTTPCookieProcessor; HTTPDefaultErrorHandler;
 HTTPDigestAuthHandler; HTTPErrorProcessorl; HTTPHandler;
 HTTPPasswordMgr; HTTPPasswordMgrWithDefaultRealm;
 HTTPRedirectHandler; HTTPSHandler;OpenerDirector;ProxyBasicAuthHandler
 ProxyDigestAuthHandler; ProxyHandler; Request; URLopener;
 UnknowHandler; build_opener; getproxies; install_opener; pathname2url;
 url2pathname; urlcleanup; urlopen; urlretrieve;

urllib.response: addbase; addclosehook; addinfo; addinfourl;

urllib.robotparser: RobotFileParser

另外，这个方法对于有防盗链的链接只能下载到防盗链图片。
