Python 二进制API'；allOrders'；（HMAC sha256）错误1022

大约在过去的一周里，我一直在努力思考签名HMACSHA256请求的概念

在这个例子中，我只是想得到所有当前订单的列表。 我想我已经弄明白了，但由于某种原因，这仍然行不通。 API密钥是新的…我尝试了读和写版本，我的IP被列入了白名单

我收到{'code'：-1022，'msg'：'此请求的签名无效。}

我的代码

import hmac
import hashlib

    def GetAllOrders(pair,orderid='',start='',finish='',limit='',window=''):

        # Credentials #

        SecretKey = Credentials.Binance.ReadSecretKey

        BaseURL = 'https://api.binance.com'
        EndPoint = '/api/v3/allOrders'
                
        # Required #
        Pair = '?symbol='+str(pair)                                     
        Time = '&timestamp='+str(int(time.time()*1000))  

        # Optional #
        if orderid != '':

        # HMAC #
        HMAC = hmac.new(bytes(SecretKey.encode('utf-8')), 
                        (Pair+OrderID+Start+Finish+Limit+Window+Time).encode('utf-8'),
                        hashlib.sha256).hexdigest()
        
        # Signature #                    
        Signature = '&signature='+str(HMAC)
        
        # Headers #
        Headers = {'X-MBX-APIKEY': ApiKey}

        # Request #
        JSON = requests.get(BaseURL+EndPoint+Pair+OrderID+Start+Finish+Limit+Window+Time+Signature,headers=Headers).json()

        return JSON

print(Private.GetAllOrders(pair='BTCUSDT'))

任何帮助都将不胜感激……

我想出来了

HMAC不会将“？”识别为参数的开头，而URL（API）会识别

以下几行应该是这样的

# Required #
Pair = 'symbol='+str(pair)   

# Request #
JSON = requests.get(BaseURL+EndPoint+'?'+Pair+OrderID+Start+Finish+Limit+Window+Time+Signature,headers=Headers).json()
