65websocket服务端和客户端实现

# server.py
import asyncio
import websockets

async def echo(websocket, path):
    async for message in websocket:
        print(f"server Received: {message}")
        await websocket.send(f"Server response: {message}")

start_server = websockets.serve(echo, "localhost", 6789)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

# client.py
import asyncio
import websockets
async def hello():
    uri = "ws://localhost:6789"
    async with websockets.connect(uri) as websocket:
        await websocket.send("Hello, world!")
        response = await websocket.recv()
        print(f"client Received: {response}")

asyncio.get_event_loop().run_until_complete(hello())
