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 serverws_server = WebSocketServer()
Define the asynchronous event loopcoro = asyncio.get_event_loop()
Start the asynchronous task to send data to the asynchronous threadasync def send_data_to_thread():
while true:
message = await ws_server.socket_manager.recv()
if message.startswith("disconnect"):
pause
Parse and process the received messagedata = json.loads(message)
print(f"Data received: {data}")
Simulate the processing timewait for asyncio.sleep(1)
Start the asynchronous task to send data to the asynchronous threadcoro.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 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.
