复制代码 代码如下:

"""Gravatar <https://en.gravatar.com/site/implement/>_"""

import code for encoding urls and generating md5 hashes

import urllib2, hashlib

Make response slow if verify whether default avatar or not.

So let js do it, see /static/js/article.js.

def gravatar_url(email, size=40, verify_default=False):
"""Construct the gravatar url."""
gravatar_url = ''.join(['http://www.gravatar.com/avatar/',
hashlib.md5(email.lower()).hexdigest(), '?s=%d' % size])

if default return None

if (verify_default):  
    gravatar_url += '&d;=404'  
    try:  
        urllib2.urlopen(gravatar_url)  
    except urllib2.URLError, e:  
        return None  
return gravatar_url

if name == 'main':
import webbrowser as wb
for email in ['xxx@gmail.com']:
url = gravatar_url(email)
print(url)
if url:
wb.open(url)
