本文介绍了如何利用Python的asyncio库来实现一个简单的echo服务器。通过这种方式，可以创建一个能够响应客户端并返回相同消息的服务器端应用。

asyncio实现echo服务端

async def handle(reader:StreamReader, writer:StreamWriter):

    while True:
        writers = []
        data = await reader.read(1024)
        if not data or data == b'quit':
            print('quit !!!')
            break
        # print(1,reader, 2,writer)
        writers.append(writer)
        print(3, writers)
        client = writer.get_extra_info('peername')
        # print(client)
        message = '{} your msg {}'.format(client, data.decode()).encode()
        for i in writers:
            i.write(message)
        await writer.drain()
    writer.close()

loop = asyncio.get_event_loop()
coro = asyncio.start_server(handle, '127.0.0.1', 9999, loop=loop)
server = loop.run_until_complete(coro)
print(server)

try:
    loop.run_forever()
except KeyboardInterrupt:
    pass
finally:
    server.close()
    loop.run_until_complete(server.wait_closed())
    loop.close()
