各位大佬问一下这段代码从python2改成python3怎么改啊，谢谢各位大佬了

host = 'http://jisutqybmf.market.alicloudapi.com'
    path = '/weather/query'
    method = 'GET'
    appcode = '我的appcode'
    querys = 'city=%s&citycode=citycode&cityid=cityid&ip=ip&location=location' % cityname
    bodys = {}
    url = host + path + '?' + querys

    request = urllib2.Request(url)
    request.add_header('Authorization', 'APPCODE ' + appcode)
    response = urllib2.urlopen(request)
    content = response.read()

在开头加上
import sys
reload(sys)
sys.setdefaultencoding( "utf-8" )
或者直接在cmd中运行
