websockets简单例子1

services.py

import asyncio
import websockets

async def web(websocket,path=None):
    while True:
        name = await websocket.recv()
        print("收到的消息:",name)
        message = "hello,"+name
        await websocket.send(message)
        print("发送的消息",message)




async def main():
    # 启动 WebSocket 服务器
    server = await websockets.serve(web, 'localhost', 8765)
    await server.wait_closed()

# 运行主函数
asyncio.run(main())

client.py

import asyncio
import websockets


async def hello():
    async with websockets.connect('ws://localhost:8765' ) as websocket:
        while True:
            print("连接成功")
            name = input("What's your name? ")

            await websocket.send(name)
            print(f"> {name}")

            greeting = await websocket.recv()
            print(f"< {greeting}")

if __name__ == '__main__':
    asyncio.run(hello())

去掉while True

去掉while True对话只会执行一轮就结束了
