python http基本验证方法

#!usr/bin/env python# -*- coding: utf-8 -*-import urllib2 LOGIN = ""PASSWORD = ""URL = ""REALM = "Secure Archive" def handler_version(url): from urlparse import urlparse#urlparse用来将url拆成各个部分scheme netloc path params query fragment hdlr = urllib2.HTTPBasicAuthHandler()#http验证类 里面有用户名和密码 hdlr.add_password(REALM, urlparse(url)[1], LOGIN, PASSWORD)#将url 用户名 密码添加进去 opener = urllib2.build_opener(hdlr)#urlopen不支持验证等高级功能 所以自定义opener urllib2.install_opener(opener)#建立url开启器 return url def request_version(url): from base64 import encodestring#编码 req = urllib2.Request(url)#开始请求页面 b64str = encodestring('%s:%s' % (LOGIN, PASSWORD))[:-1]#将sting转换成base64-data形式 base64为一种形式的二进制编码 req.add_header("Authorization", "Basic %s" % b64str)#添加header标头 return req for funcType in ('handler', 'request'): print '***Using %s:' % funcType.upper() url = eval('%s_version' % funcType)(URL)#eval 将字符串转换成有效的表达式并返回结果 f = urllib2.urlopen(url) print f.readline() f.close()
