它不是WebSocket的替代品，但我修复了setInterval的问题。
后端app.py

@app.route('/allOrders')
@cross_origin(supports_credentials=True)
def allOrders():
    openOrders = getAllOrders("LITBUSD")
    return jsonify(openOrders) 

def getAllOrders(symbol):
    try:
        openOrders =  client.get_all_orders(symbol=symbol)
    except requests.exceptions.ConnectTimeout:
        print("timeout")
        pass 
    return openOrders

js side chart.js

setInterval(function(){ 
    fetch('http://localhost:5000/allOrders')
    .then((r) => r.json())
    .then((response) => {
        console.log(response)       
    })
 }, 3000);

我像这样在index.html中添加引用。

<script src="{{url_for('static', filename='chart.js')}}"></script>

安装Unicorn Binance WebSocket API：

pip install unicorn-binance-websocket-api

如何通过Binance WebSocket API查询所有未结订单的完整示例：

from unicorn_binance_websocket_api.manager import BinanceWebSocketApiManager
import asyncio
import logging
import os

api_key = ""
api_secret = ""

async def binance_api_stream(ubwa):
    def handle_socket_message(data):
        print(f"received data:\r\n{data}\r\n")

    ubwa.create_stream(api=True, api_key=api_key, api_secret=api_secret,
                       process_stream_data=handle_socket_message)
    ubwa.api.get_open_orders(symbol="BNBBTC")
    ubwa.stop_manager_with_all_streams()

if __name__ == "__main__":
    logging.getLogger("unicorn_binance_websocket_api")
    logging.basicConfig(level=logging.DEBUG,
                        filename=os.path.basename(__file__) + '.log',
                        format="{asctime} [{levelname:8}] {process} {thread} {module}: {message}",
                        style="{")

    ubwa = BinanceWebSocketApiManager(exchange='binance.com')

    try:
        asyncio.run(binance_api_stream(ubwa))
    except KeyboardInterrupt:
        print("\r\nGracefully stopping the websocket manager...")
        ubwa.stop_manager_with_all_streams()
