Python urlib2 TLSv1

Question

我目前正在使用urlib通过restfulapi获取一些数据。有没有一个简单的方法来指导它使用威瑟SSLv3或TLSv1。。你知道吗

   try:
        request = urllib2.Request(api_query)
        request.add_header("Authorization", "Basic %s" % self.userpass)
        f = urllib2.urlopen(request)
        response = f.read()
        f.close()
        return response
    except Exception, e:
        print "error :",e

谢谢你
