### **本人实际调用隐式api抓取okex3的期货合约行情的方法【带参数的】：** ###

    from app.exchanges.common.pandas_base import PandasBase
    
    exchange = ccxt.okex3({
        "apiKey": ExchangeAPIConfig.okex_api_v3["api_key"],
        "secret": ExchangeAPIConfig.okex_api_v3["seceret_key"],
        "password": ExchangeAPIConfig.okex_api_v3["passphrase"],
        'timeout': 30000,
        'enableRateLimit': True,
    })
    
    # 输出exchange所有方法和属性
    # print(dir(exchange))
    
    
    """
        对于有参数的隐式方法如何传参？
        GET /api/futures/v3/instruments/<instrument_id>/candles
        request(path, api='public', method='GET', params={}, headers=None, body=None) method of ccxt.okex3.okex3 instance
        Exchange.request is the entry point for all generated methods
    """
    # 输出这个方法的帮助
    # print(help(exchange.futures_get_instruments_instrument_id_candles))
    
    data = exchange.futures_get_instruments_instrument_id_candles(params={
        "instrument_id": "BTC-USDT-191227",
        "granularity": 60 * 60
    })
    
    
    print(PandasBase.generate_datatime_index_iso8601_pandas(data))
