WebSockets¶
websockets is a library for building WebSocket servers and clients in
Python with a focus on correctness and simplicity.
Built on top of asyncio, Python’s standard asynchronous I/O framework,
it provides an elegant coroutine-based API.
Here’s a client that says “Hello world!”:
#!/usr/bin/env python
import asyncio
import websockets
async def hello(uri):
async with websockets.connect(uri) as websocket:
await websocket.send("Hello world!")
asyncio.get_event_loop().run_until_complete(
hello('ws://localhost:8765'))
And here’s an echo server:
#!/usr/bin/env python
import asyncio
import websockets
async def echo(websocket, path):
async for message in websocket:
await websocket.send(message)
asyncio.get_event_loop().run_until_complete(
websockets.serve(echo, 'localhost', 8765))
asyncio.get_event_loop().run_forever()
