如何创建有效的签名消息以将订单发布到 Kucoin Future API？

Question

我正在尝试下订单，但它给了我这个错误： {"code":"400005","msg":"无效的 KC-API-SIGN"} 如果有人检查我的代码并让我知道问题，我将非常感激

import requests
import time
import base64
import hashlib
import hmac
import json
import uuid
api_key = 'XXXXXXXXXXXXXXXXXXXXXXX'
api_secret = 'XXXXXXXXXXXXXXXXXXXXXX'
api_passphrase = 'XXXXXXXXXXXXXXX'
future_base_url = "https://api-futures.kucoin.com"
clientOid = uuid.uuid4().hex
params = {
"clientOid": str(clientOid),
"side": str(side),
"symbol": str(symbol),
"type": "limit",
"leverage": "5",
"stop": "down",
"stopPriceType": "TP",
"price": str(price),
"size": int(size),
"stopPrice": str(stopprice)
}
json_params = json.dumps(params)
print(json_params)
now = int(time.time() * 1000)
str_to_sign = str(now) + 'POST' + '/api/v1/orders' + json_params
signature = base64.b64encode(hmac.new(api_secret.encode('utf-8'), str_to_sign.encode('utf-8'), hashlib.sha256).digest())
passphrase = base64.b64encode(hmac.new(api_secret.encode('utf-8'), api_passphrase.encode('utf-8'), hashlib.sha256).digest())

headers = {
"KC-API-SIGN": signature,
"KC-API-TIMESTAMP": str(now),
"KC-API-KEY": api_key,
"KC-API-PASSPHRASE": passphrase,
"KC-API-KEY-VERSION": "2",
"Content-Type": "application/json"
}
response = requests.request('POST', future_base_url + '/api/v1/orders', params=params, headers=headers)

print(response.text)
