正常http就够了，但是若是需要双向通信的话，websocket就会更加简单些。下面介绍python下的一些实践。

服务器端

选择 websocket-server，快速安装

pip install websocket-server

例子：

from websocket_server import WebsocketServer
# Called for every client connecting (after handshake)

def new_client(client, server):
    print("New client connected and was given id %d" % client['id'])
    server.send_message_to_all("Hey all, a new client has joined us")

# Called for every client disconnecting
def client_left(client, server):
    print("Client(%d) disconnected" % client['id'])

# Called when a client sends a message
def message_received(client, server, message):
    if len(message) > 200:
        message = message[:200]+'..'
    print("Client(%d) said: %s" % (client['id'], message))
    server.send_message(client, "got your message")

PORT = 9001
server = WebsocketServer(PORT, '0.0.0.0')
server.set_fn_new_client(new_client)
server.set_fn_client_left(client_left)
server.set_fn_message_received(message_received)
server.run_forever()

客户端

建议选择websocket-client，有多种创建方式，代码简洁。Github 2.3k star。可靠。
快速安装

pip install websocket-client

https://github.com/websocket-client/websocket-client

from websocket import create_connection
ws = create_connection("ws://10.26.137.129:9001/")
print("Sending 'Hello, World'...")
ws.send("Hello, World")
print("Sent")
print("Receiving...")
result = ws.recv()
print("Received '%s'" % result)
ws.close()

总结

对于python3.5以下，目前来看，当前的选择是更加实践。若是python3.5以上，可以试试
