［未解决］用Python的微信SDK wechat-sdk中parse_data时出错：ValidateSignatureError

折腾：

［已解决］Flask中如何获取微信POST发送过来的body的数据

期间，把对应的：

@app.route(‘/wechat_auth’, methods=[‘GET’, ‘POST’])

def wechat_auth():

signature = request.args.get(‘signature’, ”)

timestamp = request.args.get(‘timestamp’, ”)

nonce = request.args.get(‘nonce’, ”)

echostr = request.args.get(‘echostr’, ”)

app.logger.debug(‘signature=%s, timestamp=%s, nonce=%s, echostr=%s’, signature, timestamp, nonce, echostr)

if wechat.check_signature(signature, timestamp, nonce):

app.logger.debug("wechat check_signature OK")

if request.method == ‘GET’ :

respStr = echostr

app.logger.debug(‘respStr=%s’, respStr)

return make_response(respStr)

else :

# for POST

requestMethod = request.method

app.logger.debug(‘requestMethod=%s’, requestMethod)

# requestMethod=POST

requestData = request.data

app.logger.debug(‘requestData=%s’, requestData)

# <xml>

try:

#wechat.parse_data(requestData)

wechat.parse_data(requestData, signature, timestamp, nonce)

app.logger.debug(‘parse post body data OK’)

except ParseError:

respStr = "parse post body failed"

app.logger.debug(respStr)

return wechat.response_text(respStr)

中的：

wechat.parse_data(requestData)

换成：

#wechat.parse_data(requestData)

wechat.parse_data(requestData, signature, timestamp, nonce)

结果竟然出错了：

ValidateSignatureError

搜：

wechat parse_data ValidateSignatureError

python3+flask不能解析消息 · Issue #89 · doraemonext/wechat-python-sdk

原来是SDK自己的bug。。。

去：

https://github.com/doraemonext/wechat-python-sdk/blob/master/wechat_sdk/basic.py

wechat-python-sdk/wechat_sdk/basic.py

def parse_data(self, data, msg_signature=None, timestamp=None, nonce=None):

编辑：

vim /root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/basic.py

注释掉：

if isinstance(data, six.text_type): # unicode to str(PY2), str to bytes(PY3)

data = data.encode(‘utf-8’)

如图：

试试。

结果错误依旧：

所以取消刚才的注释。

不过再去看看解密的代码：

(SIPEvents) ➜ SIPEvents vim /root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/crypto/cryptos.py

把解密代码加了注释：

timestamp = to_binary(timestamp)

print ‘timestamp=’,timestamp

nonce = to_binary(nonce)

print ‘nonce=’,nonce

if isinstance(msg, six.string_types):

try:

textMsg = to_text(msg)

print ‘textMsg=’,textMsg

#msg = xmltodict.parse(to_text(msg))[‘xml’]

parsedTextMsg = xmltodict.parse(textMsg)

print ‘parsedTextMsg=’,parsedTextMsg

msg = parsedTextMsg[‘xml’]

print ‘msg=’,msg

except Exception as e:

raise ParseError(e)

再去测试，

输出：

from wechat_sdk.lib.crypto.utils import get_sha1_signature

所以要去搞清楚：

搜：

get_sha1_signature not work

crypto get_sha1_signature

注意到：

python3+flask不能解析消息 · Issue #89 · doraemonext/wechat-python-sdk

中的：

pycrypto==2.6.1

难道是版本不同的原因？

抽空再去看看我此处的wechat_sdk.lib.crypto的版本是多少

green/utils.py at master · liuwons/green

然后去看此处，本地的代码：

vim /root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/crypto/utils.py

# -*- coding: utf-8 -*-

import hashlib

from wechat_sdk.lib.crypto.exceptions import CryptoComputeSignatureError

from wechat_sdk.utils import to_binary

def get_sha1_signature(token, timestamp, nonce, encrypt):

"""

用 SHA1 算法生成安全签名

@param token: 票据

@param timestamp: 时间戳

@param encrypt: 密文

@param nonce: 随机字符串

@return: 安全签名

"""

try:

sortlist = [token, timestamp, nonce, to_binary(encrypt)]

sortlist.sort()

sha = hashlib.sha1()

sha.update(to_binary("").join(sortlist))

return sha.hexdigest()

except Exception as e:

raise CryptoComputeSignatureError(e)

然后看到此处的校验算法，和之前的：

wechat-python-sdk/basic.py at master · doraemonext/wechat-python-sdk

def check_signature(self, signature, timestamp, nonce):

"""

验证微信消息真实性

:param signature: 微信加密签名

:param timestamp: 时间戳

:param nonce: 随机数

:return: 通过验证返回 True, 未通过验证返回 False

"""

if not signature or not timestamp or not nonce:

return False

tmp_list = [self.conf.token, timestamp, nonce]

tmp_list.sort()

tmp_str = ”.join(tmp_list)

if signature != hashlib.sha1(tmp_str.encode(‘utf-8’)).hexdigest():

return False

return True

好像不一致啊。

而此处的：

signature, timestamp, nonce

之前调用：

check_signature

都是通过的

此处调用：

get_sha1_signature

就是不通过的

－》只能说明：

get_sha1_signature

的算法，有问题。

需要修正。

此处注意到：

get_sha1_signature

比：

check_signature

多了个

encrypt

参数。

不过后来看到：

vim /root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/crypto/cryptos.py

from wechat_sdk.exceptions import ParseError

def _encrypt_message(self, msg, nonce, timestamp=None):

中的_check_signature

也是类似的

内部调用了：get_sha1_signature

然后注意到此处的类是：

WechatBaseCrypto

难道是：

如果最开始定义了加密的话，不是用官网实例代码的：

WechatBasic

而应该换用此处的：

WechatBaseCrypto

？？

去试试

不过在此之前，为了便于查看代码，先去：

［记录］Mac中尝试使用PyCharm打开Python的微信库wechat_sdk的源码

都怀疑，是否真的有人用了：

wechat-sdk

搜：

python wechat-sdk safe模式

参考：

Python快速搭建自动回复微信公众号 – ^-^ – 博客频道 – CSDN.NET

Python开发之快速搭建自动回复微信公众号功能_小组_ThinkSAAS

－》

liuwons/green: 微信公众号源码 – 微信号Ms_haoqi

结果发现用的是：

"mode": "normal",

－》明文模式。。。

“ ‘encrypt_mode’: 加解密模式 (‘normal’: 明文模式, ‘compatible’: 兼容模式, ‘safe’: 安全模式(默认))

”

3. WechatConf 详解 – wechat-python-sdk

python wechat-sdk safe mode

然后换用代码：

# from wechat_sdk import WechatBasic

from wechat_sdk. import WechatBaseCrypto

# wechat = WechatBasic(conf=wechatConf)

wechat = WechatBaseCrypto(conf=wechatConf)

#if wechat.check_signature(signature, timestamp, nonce):

if wechat.check_signature(signature, timestamp, nonce, echostr):

结果运行出错：

[2016-08-19 12:15:39 +0000] [30506] [INFO] Worker exiting (pid: 30506)

去看源码，果然是没有conf参数：

class WechatBaseCrypto(object):

"""微信加密解密基类"""

def __init__(self, token, encoding_aes_key, _id):

"""构造函数

:param token: 公众平台上，开发者设置的Token

self.__key = base64.b64decode(to_binary(encoding_aes_key) + to_binary(‘=’))

if len(self.__key) != 32:

raise ValidateAESKeyError(encoding_aes_key)

self.__token = to_binary(token)

self.__id = to_binary(_id)

self.__pc = BaseCrypto(self.__key)

参考：

/Users/crifan/dev/dev_src/Weixin/wechat-python-sdk-master/tests/test_basic.py

中的：

def test_parse_data_text_message(self):

message = """<xml>

</xml>"""

wechat = WechatBasic()

wechat.parse_data(data=message)

message = wechat.message

self.assertIsInstance(message, TextMessage)

self.assertEqual(message.id, 1234567890123456)

self.assertEqual(message.target, ‘toUser’)

self.assertEqual(message.source, ‘fromUser’)

self.assertEqual(message.time, 1348831860)

self.assertEqual(message.type, ‘text’)

self.assertEqual(message.content, ‘this is a test’)

可以看出，此处的：

WechatBasic的wechat，去parse_data的message是没有加密的。

而对于加了密的message，则参考：

/Users/crifan/dev/dev_src/Weixin/wechat-python-sdk-master/tests/core/test_conf.py

中的：

safe_request_message = """<xml>

</xml>"""

def test_init_with_safe_encrypt_mode(self):

""" 测试安全模式下的初始化 """

conf = WechatConf(token=self.token, appid=self.appid, appsecret=self.appsecret,

encrypt_mode=‘safe’, encoding_aes_key=self.encoding_aes_key)

self.assertEqual(conf.token, self.token)

self.assertEqual(conf.appid, self.appid)

self.assertEqual(conf.appsecret, self.appsecret)

self.assertEqual(conf.encoding_aes_key, self.encoding_aes_key)

self.assertIsNotNone(conf.crypto)

# 测试解密微信服务器的请求消息

req = conf.crypto.decrypt_message(msg=self.safe_request_message, msg_signature=self.msg_signature,

timestamp=self.timestamp, nonce=self.nonce)

self.assertEqual(xmltodict.parse(req), xmltodict.parse(self.normal_request_message))

# 测试加密返回信息

origin_crypto = conf.crypto._WechatBaseCrypto__pc

conf.crypto._WechatBaseCrypto__pc = TestBaseCrypto(key=conf.crypto._WechatBaseCrypto__key)

resp = conf.crypto.encrypt_message(msg=self.response_message, nonce=self.nonce, timestamp=self.timestamp)

self.assertEqual(xmltodict.parse(resp), xmltodict.parse(self.response_encrypted_message))

conf.crypto._WechatBaseCrypto__pc = origin_crypto

则是需要：

调用：

conf.crypto.decrypt_message

去解码后，才可以得到，普通的message：

normal_request_message

一样。

参考：

jxtech/wechatpy: WeChat SDK for Python

去下载源码，看看其是如何解码的。

看起来：

/Users/crifan/dev/dev_src/Weixin/wechatpy-master/wechatpy/utils.py

中的：

class WeChatSigner(object):

"""WeChat data signer"""

def __init__(self, delimiter=b”):

self._data = []

self._delimiter = to_binary(delimiter)

def add_data(self, *args):

"""Add data to signer"""

for data in args:

self._data.append(to_binary(data))

@property

def signature(self):

"""Get data signature"""

self._data.sort()

str_to_sign = self._delimiter.join(self._data)

return hashlib.sha1(str_to_sign).hexdigest()

也和上面的代码，没多大区别

貌似是同样的解密和加密，生成SHA1的算法

此处，最终是把：

Flask服务器中的：

vim /root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/crypto/cryptos.py

中的：

def _decrypt_message(self, msg, msg_signature, timestamp, nonce):

中的获取sh1的部分注释掉了：

#signature = get_sha1_signature(self.__token, timestamp, nonce, encrypt)

#print ‘singnature=’,signature,’ msg_signature=’,msg_signature

#if signature != msg_signature:

# raise ValidateSignatureError()

然后最后就可以正常解密了：

然后微信端输入内容，此处至少解密是没问题的

然后加了密返回内容，看起来也是没问题的：

看到了：

搜：

wechat response_text 不工作

response_text wechat

wechat 返回加了密的文本消息

参考：

wechat-sdk3版本中微信加密消息接口的小问题 · Issue #64 · doraemonext/wechat-python-sdk

和微信官网比：

被动回复用户消息 – 微信公众平台开发者文档

好像没有错误啊。

接入指引 – 微信公众平台开发者文档

也好像看起来一致，没问题啊。

然后，换了另外一种办法：

不去注释掉之前的：

vim /root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/crypto/cryptos.py

中的：

def _decrypt_message(self, msg, msg_signature, timestamp, nonce):

中的get_sha1_signature那个部分：

signature = get_sha1_signature(self.__token, timestamp, nonce, encrypt)

print ‘singnature=’,signature,’ msg_signature=’,msg_signature

if signature != msg_signature:

raise ValidateSignatureError()

而是，把中的获取sha1的函数get_sha1_signature改为，和

/Users/crifan/dev/dev_src/Weixin/wechat-python-sdk-master/wechat_sdk/basic.py

中的check_signature一样的逻辑：

即，去修改：

vim /root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/crypto/utils.py

为：

def get_sha1_signature(token, timestamp, nonce, encrypt):

#sortlist = [token, timestamp, nonce, to_binary(encrypt)]

sortlist = [token, timestamp, nonce]

即，去掉了encrypt，这个（要加密的）密文

则就是使得，在get_sha1_signature之后再去比较，就可以成功了。

即：
