我想從外部 websocket 獲取加密貨幣數(shù)據(jù)并將其保存到數(shù)據(jù)庫。為了producer.py從頭開始運(yùn)行，我將其添加INSTALLED_APPS到settings.py：INSTALLED_APPS = [    'crypto.spot.producer',]producer.py是：from .models import Spotasync def message(u, t, interval, timeout):    async with websockets.connect(uri=u + '?token=' + t, ping_interval=interval, ping_timeout=timeout) as websocket:        await websocket.send(json.dumps({"id": "4848226",                                         "type": "subscribe",                                         "topic": "/market/ticker:all",                                         "response": True}))        while True:            response = await websocket.recv()            result = json.loads(response)            '''            write result to django model (Spot)            '''while True:    response = r.post('https://api.kucoin.com/api/v1/bullet-public')    payload = json.loads(response.text)    uri = payload['data']['instanceServers'][0]['endpoint']    token = payload['data']['token']    ping_interval = payload['data']['instanceServers'][0]['pingInterval']    ping_timeout = payload['data']['instanceServers'][0]['pingTimeout']    asyncio.get_event_loop().run_until_complete(message(uri, token, ping_interval, ping_timeout))    asyncio.get_event_loop().run_forever()
