Http Basic Authorizaition验证

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
