我正在学习如何构建 Python 交易机器人，我正处于编程的第一步，我需要一些帮助。我在尝试使用 API 连接器从基本 URL 和来自 bitmex.com 的 Websocket 获取信息时遇到了这个错误。

这是连接到主机的代码：

BitmexClient 类：

def __init__(self, public_key: str, secret_key: str, testnet: bool):
    if testnet:
        self._base_url = "https://testnet.bitmex.com"
        self._wss_url = "wss://testnet.bitmex.com/realtime"
    else:
        self._base_url = "https://www.bitmex.com"
        self._wss_url = "wss://www.bitmex.com/realtime"

    self._public_key = public_key
    self._secret_key = secret_key

    self._ws = None

    self.contracts = self.get_contracts()
    self.balances = self.get_balances()

    self.prices = dict()

    t = threading.Thread(target=self._start_ws)
    t.start()

    logger.info("Bitmex Client successfully initialized")

与错误相关的代码段：

def get_contracts(self) -> typing.Dict[str, Contract]:

    instruments = self._make_request("GET", "api/v1/instrument/active", dict())

    contracts = dict()

    if instruments is not None:
        for s in instruments:
            contracts[s['symbol']] = Contract(s, "bitmex")

    return contracts

def get_balances(self) -> typing.Dict[str, Balance]:

    data = dict()
    data['currency'] = "all"

    margin_data = self._make_request("GET", "api/v1/user/margin", data)

    balances = dict()

    if margin_data is not None:
        for a in margin_data:
            balances[a['currency']] = Balance(a, "bitmex")

    return balances

这是错误：

看起来问题在于您正在尝试连接到“testnet.bitmex.comapi”主机。

主机应该是“testnet.bitmex.com”。
