操纵Websocket值

我正在尝试第一次与Python处理Websocket。

我创建了两个客户，我想对这两个结果进行一些计算。（哪个是实时加密价格）

是否可以添加或乘以数字的这些结果？

import websockets
import asyncio
import json
from binance import AsyncClient, BinanceSocketManager

async def upbit_ws_client():
    uri = "wss://api.upbit.com/websocket/v1"
    async with websockets.connect(uri) as websocket:
        subscribe_fmt = [
            {"ticket": "test"},
            {
                "type": "ticker",
                "codes": ["KRW-BTC"],
                "isOnlyRealtime": True
            },
            {"format": "SIMPLE"}
        ]
        subscribe_data = json.dumps(subscribe_fmt)
        await websocket.send(subscribe_data)

        while True:
            data = await websocket.recv()
            data = json.loads(data)
            print(data['cd'], data['hp'])


async def binance_ws_client():
    client = await AsyncClient.create()
    bm = BinanceSocketManager(client)
    ts = bm.symbol_book_ticker_socket("BTCUSDT")

    async with ts as tscm:
        while True:
            res = await tscm.recv()
            print(res['b'], res['a'])


if __name__ == '__main__':
    my_loop = asyncio.get_event_loop()
    my_loop.run_until_complete(asyncio.gather(*[upbit_ws_client(), binance_ws_client()]))
    my_loop.close()

I'm trying to handling websockets with python for the first time.

I created two clients and I want to do some calculate with these two results.
(which is realtime crypto price)

Is it possible to add or multiply numbers of theses result?

import websockets
import asyncio
import json
from binance import AsyncClient, BinanceSocketManager

async def upbit_ws_client():
    uri = "wss://api.upbit.com/websocket/v1"
    async with websockets.connect(uri) as websocket:
        subscribe_fmt = [
            {"ticket": "test"},
            {
                "type": "ticker",
                "codes": ["KRW-BTC"],
                "isOnlyRealtime": True
            },
            {"format": "SIMPLE"}
        ]
        subscribe_data = json.dumps(subscribe_fmt)
        await websocket.send(subscribe_data)

        while True:
            data = await websocket.recv()
            data = json.loads(data)
            print(data['cd'], data['hp'])


async def binance_ws_client():
    client = await AsyncClient.create()
    bm = BinanceSocketManager(client)
    ts = bm.symbol_book_ticker_socket("BTCUSDT")

    async with ts as tscm:
        while True:
            res = await tscm.recv()
            print(res['b'], res['a'])


if __name__ == '__main__':
    my_loop = asyncio.get_event_loop()
    my_loop.run_until_complete(asyncio.gather(*[upbit_ws_client(), binance_ws_client()]))
    my_loop.close()

结果是字符串，因此您需要首先将它们转换为浮点，以使您可以计算：

a = float(res['a'])
b = float(res['b'])

然后您可以提取a和b：

result = a - b
print(result)

您可以将其添加到代码下：

import websockets
import asyncio
import json
from binance import AsyncClient, BinanceSocketManager

async def upbit_ws_client():
    uri = "wss://api.upbit.com/websocket/v1"
    async with websockets.connect(uri) as websocket:
        subscribe_fmt = [
            {"ticket": "test"},
            {
                "type": "ticker",
                "codes": ["KRW-BTC"],
                "isOnlyRealtime": True
            },
            {"format": "SIMPLE"}
        ]
        subscribe_data = json.dumps(subscribe_fmt)
        await websocket.send(subscribe_data)

        while True:
            data = await websocket.recv()
            data = json.loads(data)
            print(data['cd'], data['hp'])


async def binance_ws_client():
    client = await AsyncClient.create()
    bm = BinanceSocketManager(client)
    ts = bm.symbol_book_ticker_socket("BTCUSDT")

    async with ts as tscm:
        while True:
            res = await tscm.recv()
            print(res['b'], res['a'])
            
            a = float(res['a'])
            b = float(res['b'])
            result = a - b
            print(result)            


if __name__ == '__main__':
    my_loop = asyncio.get_event_loop()
    my_loop.run_until_complete(asyncio.gather(*[upbit_ws_client(), binance_ws_client()]))
    my_loop.close()

The results are strings so you need to convert them to floats first in order to have a data type which you can calculate:

a = float(res['a'])
b = float(res['b'])

Then you can substract a and b:

result = a - b
print(result)

which you can add to your code like below:

import websockets
import asyncio
import json
from binance import AsyncClient, BinanceSocketManager

async def upbit_ws_client():
    uri = "wss://api.upbit.com/websocket/v1"
    async with websockets.connect(uri) as websocket:
        subscribe_fmt = [
            {"ticket": "test"},
            {
                "type": "ticker",
                "codes": ["KRW-BTC"],
                "isOnlyRealtime": True
            },
            {"format": "SIMPLE"}
        ]
        subscribe_data = json.dumps(subscribe_fmt)
        await websocket.send(subscribe_data)

        while True:
            data = await websocket.recv()
            data = json.loads(data)
            print(data['cd'], data['hp'])


async def binance_ws_client():
    client = await AsyncClient.create()
    bm = BinanceSocketManager(client)
    ts = bm.symbol_book_ticker_socket("BTCUSDT")

    async with ts as tscm:
        while True:
            res = await tscm.recv()
            print(res['b'], res['a'])
            
            a = float(res['a'])
            b = float(res['b'])
            result = a - b
            print(result)            


if __name__ == '__main__':
    my_loop = asyncio.get_event_loop()
    my_loop.run_until_complete(asyncio.gather(*[upbit_ws_client(), binance_ws_client()]))
    my_loop.close()
