odoo後臺實現微信公衆號驗證

在微信公衆號開發的其中一個步驟是微信服務器調用咱們本身的網站驗證身份，這一步微信服務器會傳遞過來4個參數，但是按照官方的寫法，卻沒法驗證經過，下面是官方的驗證方法：

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" #請按照公衆平臺官網\基本配置中信息填寫

            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

網上有網友寫的專門的模塊，通過實際驗證可行，現將這部分的代碼單獨抽取以下：

    @http.route('/wechat_public_account_auth/validate', type='http', auth="none", methods=["GET"])
    def validate_auth(self, signature, timestamp, nonce, echostr, **kw):
        token = "guoodoo"  # 請按照公衆平臺官網\基本配置中信息填寫
        list = [token, timestamp, nonce]
        list_data = []
        for data in list:
            list_data.append(self.to_binary(data))
        list_data.sort()
        _delimiter = self.to_binary(b'')
        str_to_sign = _delimiter.join(list_data)
        hashcode = hashlib.sha1(str_to_sign).hexdigest()
        if hashcode == signature:
            return echostr
        else:
            return ""

    def to_binary(self, value, encoding='utf-8'):
        """Convert value to binary string, default encoding is utf-8
        :param value: Value to be converted
        :param encoding: Desired encoding
        """
        if not value:
            return b''
        if isinstance(value, six.binary_type):
            return value
        if isinstance(value, six.text_type):
            return value.encode(encoding)

        return self.to_text(value).encode(encoding)

    def to_text(self, value, encoding='utf-8'):
        """Convert value to unicode, default encoding is utf-8
        :param value: Value to be converted
        :param encoding: Desired encoding
        """
        if not value:
            return ''
        if isinstance(value, six.text_type):
            return value
        if isinstance(value, six.binary_type):
            return value.decode(encoding)

        return six.text_type(value)

通過比較發現，主要的不一樣是對token,timestap,nonce字符串進行了編碼，代碼寫好以後，在微信公衆平臺上填寫相關信息進行測試，以下圖所示.

若是經過，微信開放平臺會記錄下咱們的信息，若是失敗沒法保存。
