HTTP Basic Authorization

Http Basic Authorizaition验证的原理详见
http://zh.wikipedia.org/wiki/HTTP%E5%9F%BA%E6%9C%AC%E8%AE%A4%E8%AF%81

python实现：
import urllib2
import sys
import re
import base64
from urlparse import urlparse

theurl = 'http://api.minicloud.com.cn/statuses/friends_timeline.xml'

username = 'qleelulu'
password = 'XXXXXX'  # 你信这是密码吗？

base64string = base64.encodestring(
                '%s:%s' % (username, password))[:-1] #注意哦，这里最后会自动添加一个\n
authheader =  "Basic %s" % base64string
req.add_header("Authorization", authheader)
try:
    handle = urllib2.urlopen(req)
except IOError, e:
    # here we shouldn't fail if the username/password is right
    print "It looks like the username or password is wrong."
    sys.exit(1)
thepage = handle.read()

原理就是添加了请求头Authorization
