NetSuite python TBA 身份验证

Question

我对使用 SOAP 进行 NetSuite 调用这一领域还不熟悉。因此，我对如何解决问题的思考可能完全错误。这是我试图解决的问题： - 语言：Python+Zeep - 我想将我的应用程序从电子邮件传递转移到基于令牌的身份验证。

在 Python 中，我能够生成 TokenPassport 的所有参数。 这是我感到困惑的地方：我在堆栈上查找了一些代码，发现人们正在使用 client.service.login() 方法来登录。此方法采用护照而不是 tokenpassport 对象。 是否有一个单独的方法可以使用 tokenpassport obj 进行登录？或者我是否需要使用参数生成（硬编码）一个 XML，并将其作为数据传入标头？

谢谢 T

Answer 1

希望下面的代码可以帮助刚入门的人。

base = '&'.join([nsAccountID, consumerKey, token, Nonce, currentTime])
key = '&'.join([consumerSecret, tokenSecret])
digest = hmac.new(str.encode(key), msg=str.encode(base), digestmod=hashlib.sha256).digest()
signature = base64.b64encode(digest).decode()

tokenPassport = client.get_type('ns0:TokenPassport')
PassportSignature = client.get_type('ns0:TokenPassportSignature')
tokenPassportSignature = PassportSignature(signature, "HMAC-SHA256" )
clientPass = tokenPassport(account=nsAccountId, consumerKey = consumerKey, token= token, nonce= Nonce, timestamp=currentTime, signature=tokenPassportSignature)


search = client.get_type('ns5:ItemSearchBasic')
searchCriteriaComplex = client.get_type('ns0:SearchStringField')
searchCriteria = searchCriteriaComplex(searchValue= "Test Display Name - tax", operator="is")
searchItem = search(displayName = searchCriteria)
testRes = client.service.search(searchRecord= searchItem, _soapheaders={"tokenPassport": clientPass})

我没有对此进行更深入的研究，而是尝试了 netsuite，这要好得多。

Answer 3

这是我生成 TokenPassport 的方法。

    def _generateTimestamp(self):
        return str(int(time()))

    def _generateNonce(self, length=20):
        """Generate pseudorandom number
        """
        return ''.join([str(random.randint(0, 9)) for i in range(length)])

    def _getSignatureMessage(self, nonce, timestamp):
        return '&'.join(
            (
                self._setting['ACCOUNT'],
                self._setting['CONSUMER_KEY'],
                self._setting['TOKEN_ID'],
                nonce,
                timestamp,
            )
        )

    def _getSignatureKey(self):
        return '&'.join((self._setting['CONSUMER_SECRET'], self._setting['TOKEN_SECRET']))

    def _getSignatureValue(self, nonce, timestamp):
        key = self._getSignatureKey()
        message = self._getSignatureMessage(nonce, timestamp)
        hashed = hmac.new(
            key=key.encode('utf-8'),
            msg=message.encode('utf-8'),
            digestmod=hashlib.sha256
        ).digest()
        return base64.b64encode(hashed).decode()

    @property
    def tokenPassport(self):
        TokenPassport = self.getDataType("ns0:TokenPassport")
        TokenPassportSignature = self.getDataType("ns0:TokenPassportSignature")

        nonce = self._generateNonce()
        timestamp = self._generateTimestamp()
        tokenPassportSignature = TokenPassportSignature(
            self._getSignatureValue(nonce, timestamp),
            algorithm='HMAC-SHA256'
        )

        return TokenPassport(
            account=self._setting['ACCOUNT'],
            consumerKey=self._setting['CONSUMER_KEY'],
            token=self._setting['TOKEN_ID'],
            nonce=nonce,
            timestamp=timestamp,
            signature=tokenPassportSignature
        )

Zeep 很棒 - 但我想要一个在客户端内指定命名空间或替代查找的选项。但这是当前（2023 年）使用 zeep 访问 Netsuite 的方式，并需要修改服务地址。

def createNonce(length=20):
    return ''.join([str(random.randint(0, 9)) for i in range(length)])

def createSignature(passport, tokenSecret, consumerSecret):
    signatureKey = f"{urllib.parse.quote_plus(consumerSecret)}&{urllib.parse.quote_plus(tokenSecret)}"
    baseString = f"{passport.account}&{passport.consumerKey}&{passport.token}&{passport.nonce}&{passport.timestamp}"

    return base64.b64encode(hmac.digest(signatureKey.encode('utf-8'), baseString.encode('utf-8'), hashlib.sha256))

--------------------------------------------------------------------------------------
client = zeep.CachingClient(wsdl=netsuiteWSDL)
client.service._binding_options["address"] = (nsURL + nsURLPath)
#service = client.create_service(netsuiteBinding, address = (nsURL + nsURLPath) )

TokenPassport = client.get_type("ns0:TokenPassport");
tokenPassport = TokenPassport(
    account = nsAccount,
    consumerKey = consumerKey,
    token = tokenKey,
    nonce = createNonce(),
    timestamp = str(int(datetime.now().timestamp()))
)

TokenPassportSignature = client.get_type("ns0:TokenPassportSignature")
hashAlgorithm = "HMAC-SHA256"
tokenPassport["signature"] = TokenPassportSignature(createSignature(tokenPassport, tokenSecret, consumerSecret), hashAlgorithm)

RecordType = client.get_type("ns1:RecordType")

RecordRef = client.get_type("ns0:RecordRef")
recordRef = RecordRef(
    internalId = "14764193",
    type = RecordType("customer")
)

print(client.service.get(recordRef, _soapheaders = { "tokenPassport": tokenPassport } ))

可能有多种方法可以利用自动绑定，但我喜欢清晰。具有讽刺意味的是，因为我不想在命名空间中搜索类型和方法。
