python - b'{"error": {"message": "HMAC authentication key and signature is given, but they are invalid.", "error_code": 41}}'

Question

我遇到了 API 调用/配置问题。相同的 API 密钥在其他地方工作，所以我知道它不是密钥，并且密钥确实具有正确的权限。

                      'My_secret')


def getDashboard():
    global nonce

    nonce = str(int(datetime.datetime.timestamp(datetime.datetime.now())*1000000))

    url = 'https://localbitcoins.com/api/dashboard/'

while True:

    print(datetime.datetime.now())
    localBitcoinsDashboardContacts = getDashboard()['contact_list']
    if len(localBitcoinsDashboardContacts) > 0:
        print("You have open trades")
        for contact in localBitcoinsDashboardContacts:
            trade_type = contact['data']['advertisement']['trade_type']
            contact_id = contact['data']['contact_id']

        mesages = gettrademessages(contact_id)['data']['message_count']
        if mesages <= 2:
            print('sending message ')
            print('yeet')
            head = {
                "msg": "this is a message / alert",
                'Apiauth-Key': hmac_key,
                'Apiauth-Nonce': nonce,
                'Apiauth-Signature': signature,
            }

            cid = contact['data']['contact_id']
            resp = requests.post(f"https://localbitcoins.com/api/contact_message_post/{cid}", headers=head)
            print(resp.content)

        else:
            print('waiting for trade.......')

    time.sleep(10)

不太确定为什么会出现此错误，我认为这与从全局签名、令牌和其他方面调用有关。如您所知，在编码方面我有点新手
