微信公众平台 token 验证失败 python3

官方文档handle.py python2.7

# -*- coding: utf-8 -*-
# filename: handle.py

import hashlib
import web

class Handle(object):
    def GET(self):
        try:
            data = web.input()
            if len(data) == 0:
                return "hello, this is handle view"
            signature = data.signature
            timestamp = data.timestamp
            nonce = data.nonce
            echostr = data.echostr
            token = "xxxx" #请按照公众平台官网\基本配置中信息填写

            list = [token, timestamp, nonce]
            list.sort()
            sha1 = hashlib.sha1()
            map(sha1.update, list)
            hashcode = sha1.hexdigest()
            print "handle/GET func: hashcode, signature: ", hashcode, signature
            if hashcode == signature:
                return echostr
            else:
                return ""
        except Exception, Argument:
            return Argument

修改如下handle.py python3

# -*- coding: utf-8 -*-
# filename: handle.py

import hashlib
import web

class Handle(object):
    def GET(self):
        try:
            data = web.input()
            if len(data) == 0:
                return "hello, this is handle view"
            signature = data.signature
            timestamp = data.timestamp
            nonce = data.nonce
            echostr = data.echostr
            token = "xxxx" #请按照公众平台官网\基本配置中信息填写
            list = [token, timestamp, nonce]
            list.sort()
            sha1 = hashlib.sha1()
            sha1.update(list[0].encode("utf-8"))
            sha1.update(list[1].encode("utf-8"))
            sha1.update(list[2].encode("utf-8"))
            hashcode = sha1.hexdigest() #获取加密串


            print ("handle/GET func: hashcode, signature: ", hashcode, signature)
            if hashcode == signature:
                return echostr
            else:
                return ""
        except Exception as Argument:
            return Argument
