Python的HTTP Basic认证

标签：python   http协议   base64   认证   basic   

1. 客户端向服务器请求数据，请求的内容可能是一个网页或者是一个其它的MIME类型，此时，假设客户端尚未被验证，则客户端提供如下请求至服务器:

         Get/index.html HTTP/1.0
         Host:www.baidu.com

2. 服务器向客户端发送验证请求代码401,服务器返回的数据大抵如下：

        HTTP/1.0 401 Unauthorised
        Server: SokEvo/1.0
        WWW-Authenticate: Basic realm="google.com"
        Content-Type: text/html
        Content-Length: xxx

        Get /index.html HTTP/1.0
        Host:www.google.com
        Authorization: Basic xxxxxxxxxxxxxxxxxxxxxxxxxxxx

         import urllib2
         from base64 import encodestring

         url = 'http://XXX.XXX.X.XX'
         user = 'a'
         passwd = 'aa' 

         req = urllib2.Request(url)
         basestr = encodestring('%s:%s' % (user,passwd))[:-1]
         req.add_header('Authorization','Basic %s' % basestr)

         f = urllib2.urlopen(req)

       import urllib2

        url = 'http://XXX.XXX.X.XX'
        user = 'a'
        passwd = 'aa'

        hdlr = urllib2.HTTPBasicAuthHandler()
        hdlr.add_password('hello',url,user,passwd)  ##此处需添入realm
        opener = urllib2.build_opener(hdlr)
        urllib2.install_opener(opener)

        f = urllib2.urlopen(url)

    为了更通用我们来用HTTPPasswordMgrWithDefaultRealm密码管理器来实现:

        import urllib2

        url = 'http://XXX.XXX.X.XX'
        user = 'a'
        passwd = 'aa'

        psmg = urllib2.HTTPPasswordMgrWithDefaultRealm() 
        psmg.add_password(None,url,user,passwd)
        hdlr = urllib2.HTTPBasicAuthHandler(psmg)
        opener = urllib2.build_opener(hdlr)
        urllib2.install_opener(opener)

        f = urllib2.urlopen(url)
