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)

            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:

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:

ValidateSignatureError

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:

对应着代码:

        signature = get_sha1_signature(self.__token, timestamp, nonce, encrypt)
        print ‘singnature=’,signature,’ msg_signature=’,msg_signature
        if signature != msg_signature:
            raise ValidateSignatureError()

搜源码中的get_sha1_signature:

只有:

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

            raise ValidateSignatureError(e)
    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:

换成:

    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。

结果试了试:

问题依旧。

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__(selfdelimiter=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:

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:
