Python Bitmex 交易机器人 - .向 api/v1/instrument/active 和 api/v1/user/margin 发出获取请求时出现连接错误

问题描述

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 bitmex.com 的 Base URL 和 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")

与错误相关的一段代码：

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：

2021-04-30 22:38:45,969 ERROR :: Connection error while making GET request to api/v1/instrument/active: HTTPSConnectionPool(host='testnet.bitmex.comapi',port=443): Max retries exceeded with url: /v1/instrument/active (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x000002065A061520>: Failed to establish a new connection: [Errno 11001] getaddrinfo Failed'))

解决方法

问题似乎在于您正在尝试连接到“testnet.bitmex.comapi”的主机。

主机应该是“testnet.bitmex.com”。
