Is there a server that can provide the code to query k-string data from the underlying websocket?
I tried to call the API interface, and the result is that the k-string data returned is incomplete and cannot be converted to json.
The interface: ws://stream.binance.com:9443/ws/ethusdt_swap@continuousKline_1h
In addition to the above-mentioned, there is also the possibility of the following data: [E]1623312213713, [E]2540.91000000
