Ethereum: Sharing Data Between Binance Twisted Internet Websocket and an Asynchronous Thread

As Ethereum continues to grow in popularity, so does the demand for reliable and efficient ways to interact with the underlying infrastructure. Examples include creating a WebSocket connection using the Binance Twisted Internet Websocket library and Python’s asynchronous threading.

In this article, we will look at how to create a WebSocket server on Binance that takes data from their API (Binance API) and sends it to an asynchronous thread for processing.

Prerequisites

Before diving into the code, make sure you have the following prerequisites:

  • Python 3.6+
  • Binance Twisted Internet Websocket Library (twisted)
  • “asyncio” library

Code

Here is a step-by-step example of how to create a WebSocket server on Binance that takes data from the API and sends it to an asynchronous thread:

from binance.websockets import BinanceSocketManager

import asyncio

import json


Define the Binance API URL (replace with your own API key)

BINANCE_API_URL = "

WebSocketServer class:

def __init__(self):

self.socket_manager = BinanceSocketManager (BINANCE_API_URL, on_open=self.on_open)

async def on_open(self, socket):

await socket.send("Connected")

async def handle_message(self, message):

print(f"Message received: {message}")

async def main():


Create a WebSocket server

ws_server = WebSocketServer()


Define the asynchronous event loop

coro = asyncio.get_event_loop()


Start the asynchronous task to send data to the asynchronous thread

async def send_data_to_thread():

while true:

message = await ws_server.socket_manager.recv()

if message.startswith("disconnect"):

pause


Parse and process the received message

data = json.loads(message)

print(f"Data received: {data}")


Simulate the processing time

wait for asyncio.sleep(1)


Start the asynchronous task to send data to the asynchronous thread

coro.run_until_complete(send_data_to_thread())

asyncio.get_event_loop().run_until_complete(coroutine(main()))

Explanation

Ethereum: Sharing data between binance twisted.internet websocket and asyncio thread

In this code, we define a “WebSocketServer” class that establishes a connection to the Binance Twisted Internet Websocket library using the “BinanceSocketManager”. When it receives a message, it prints it to the console.

Next, we create an asynchronous event loop and start two asynchronous tasks: one to send to the asynchronous thread and the other to process the received messages. The send_data_to_thread function simulates the processing time by sleeping for 1 second between each iteration of receiving the message.

Finally, we run both tasks simultaneously using `coro.run_until_complete(send_data_to_thread()).

Conclusion

In this article, we have shown how to create a WebSocket connection between Binance Twisted Internet’s Websocket library and an asynchronous thread in Python. Following the code example above, you can create your own WebSocket server that takes data from the Binance API and sends it to an asynchronous thread for processing.

Keep in mind that this is just a basic example to get you started. You may need to modify the code to suit your specific use case and handle errors more robustly.
