+
+TCP echo client using streams
+-----------------------------
+
+TCP echo client using the :func:`asyncio.open_connection` function::
+
+ import asyncio
+
+ def tcp_echo_client(message, loop):
+ reader, writer = yield from asyncio.open_connection('127.0.0.1', 8888,
+ loop=loop)
+
+ print('Send: %r' % message)
+ writer.write(message.encode())
+
+ data = yield from reader.read(100)
+ print('Received: %r' % data.decode())
+
+ print('Close the socket')
+ writer.close()
+
+ message = 'Hello World!'
+ loop = asyncio.get_event_loop()
+ loop.run_until_complete(tcp_echo_client(message, loop))
+ loop.close()
+
+.. seealso::
+
+ The :ref:`TCP echo client protocol <asyncio-tcp-echo-client-protocol>`
+ example uses the :meth:`BaseEventLoop.create_connection` method.
+
+
+.. _asyncio-tcp-echo-server-streams:
+
+TCP echo server using streams
+-----------------------------
+
+TCP echo server using the :func:`asyncio.start_server` function::
+
+ import asyncio
+
+ @asyncio.coroutine
+ def handle_echo(reader, writer):
+ data = yield from reader.read(100)
+ message = data.decode()
+ addr = writer.get_extra_info('peername')
+ print("Received %r from %r" % (message, addr))
+
+ print("Send: %r" % message)
+ writer.write(data)
+ yield from writer.drain()
+
+ print("Close the client socket")
+ writer.close()
+
+ loop = asyncio.get_event_loop()
+ coro = asyncio.start_server(handle_echo, '127.0.0.1', 8888, loop=loop)
+ server = loop.run_until_complete(coro)
+
+ # Serve requests until CTRL+c is pressed
+ print('Serving on {}'.format(server.sockets[0].getsockname()))
+ try:
+ loop.run_forever()
+ except KeyboardInterrupt:
+ pass
+
+ # Close the server
+ server.close()
+ loop.run_until_complete(server.wait_closed())
+ loop.close()
+
+.. seealso::
+
+ The :ref:`TCP echo server protocol <asyncio-tcp-echo-server-protocol>`
+ example uses the :meth:`BaseEventLoop.create_server` method.
