Websocket无法获取BTC/JPY现货交易对的K线数据

您好,我想用Websocket方式获取BTC/JPY现货交易对的K线数据,但是无返回信息,是参数有错误还是没开放该交易对,以下是订阅函数。谢谢!
params = “btcjpy@kline_1m”
def on_open(ws):
subscribe_message = {
“method”: “SUBSCRIBE”,
“params”: [params],
“id”: 1
}
ws.send(json.dumps(subscribe_message))

我在cmd上使用websocat 是能收到信息的,你看看是不是你代码哪里有写错了不。

aisling$ websocat -v "wss://stream.binance.com:9443/ws/btcjpy@kline_1d"
