它显示错误 {\"success\":false,\"error\":\"Missing parameter market\"}

import time
import hmac
from requests import Request
import requests
import json
api_key=\'\'
api_secret=\'\'
payload = json.dumps({
    \"market\": \'XRP/USDT\',
    \"side\": \'BUY\',
    \"price\": 0.7,
    \"size\": 1,
    \"type\": \"limit\",
    \"reduceOnly\": False,
    \"ioc\": False,
    \"postOnly\": False,
    \"clientId\": None
    })
ts = int(time.time() * 1000)
request = Request(\'POST\', \'https://ftx.com/api/orders\')
prepared = request.prepare()
signature_payload = f\'{ts}{prepared.method}{prepared.path_url}{payload}\'.encode()
print(signature_payload)
signature = hmac.new(api_secret.encode(), signature_payload, \'sha256\').hexdigest()
prepared.headers[\'FTX-KEY\'] = api_key
prepared.headers[\'FTX-SIGN\'] = signature
prepared.headers[\'FTX-TS\'] = str(ts)
url=\'https://ftx.com/api/orders\'
response = requests.request(\"POST\", url,headers=prepared.headers,data=payload)
print(response.text)

你能推荐如何解决吗？我尝试了很多方法，但它不起作用

您好，我知道这个问题有点老了，但也许其他人需要答案。我准备好了，它对我有用。

from requests import Request, Session
import hmac
import json
import time
from pprint import pprint


API_KEY = ""
API_SECRET = ""
SUBACCOUNT = ""


def place_order(market, side, price, size, order_type, reduceOnly, postOnly, ioc=False):
    endpoint = "https://ftx.com/api/orders"

    ts = int(time.time() * 1000)
    s = Session()
    data = json.dumps({
      "market": market,
      "side": side,
      "price": price,
      "type": order_type,
      "size": size,
      "reduceOnly": reduceOnly,
      "ioc": ioc,
      "postOnly": postOnly
    })
    request = Request("POST", endpoint, data=data)
    prepared = request.prepare()
    signature_payload = f"{ts}{prepared.method}{prepared.path_url}{data}".encode()
    signature = hmac.new(API_SECRET.encode(), signature_payload, "sha256").hexdigest()

    prepared.headers["FTX-KEY"] = API_KEY
    prepared.headers["FTX-SIGN"] = signature
    prepared.headers["FTX-TS"] = str(ts)
    prepared.headers["FTX-SUBACCOUNT"] = SUBACCOUNT

    response = s.send(prepared)
    data = response.json()
    pprint(data)
    return data
