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 = '/zb_users/upload/202003/5cvdswfybfa.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。
