Ethereum: Sharing data between Binance Twisted Internet Websocket and asyncio thread

As Ethereum’s popularity grows, so does the need for reliable and efficient ways to interact with its underlying infrastructure. One such example is creating a WebSocket connection using the Binance Twisted Internet Websocket library and the asyncio thread in Python.

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 asyncio thread for processing.

Prerequisites

Before we get to the code, make sure you have the following prerequisites:

• Python 3.6+

• Binance’s 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 gets data from their API and sends it to an asyncio thread:

from binance.websockets import BinanceSocketManager
import asyncio
import json









Define the URL for the Binance API (replace it with your own API key)
BINANCE_API_URL = "
class WebSocketServer:
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"Received message: {message}")
async def main():

Create a WebSocket server
ws_server = WebSocketServer()

Define an asyncio event loop
coro = asyncio.get_event_loop()

Start an asynchronous task to send data to an asyncio thread
async def send_data_to_thread():
while True:
message = await ws_server.socket_manager.recv()
if message.startswith("disconnect"):
break

Parse and process the received message
data = json.loads(message)
print(f"Data received: {data}")

Simulate processing time
await asyncio.sleep(1)

Run an asynchronous task to send data to the asyncio thread
coro.run_until_complete(send_data_to_thread())
asyncio.get_event_loop().run_until_complete(coroutine(main()))

Explanation

In this code, we define a WebSocketServer class that connects to Binance’s Twisted Internet Websocket library using BinanceSocketManager. When we receive an incoming message, we print it to the console.

Then, we create an asyncio event loop and run two asynchronous tasks: one to send data to the asyncio 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 messages.

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

Conclusion

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

Please note that this is just a basic example to get you started. You may need to modify the code to adapt it to your specific use case and handle errors more reliably.
