用Python实现的WebSocket服务器端

1. 按

一个项目若需用到多种语言开发请参考：基于WebSocket实现的分布式微内核项目

2. 安装库

You can use the project in three ways:

• Copy/paste the websocket_server.py file in your project and use it directly

• pip install git+https://github.com/Pithikos/python-websocket-server
  

  (latest code)

• pip install websocket-server
  

  (might not be up-to-date)

3. 代码

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))


PORT=56
server = WebsocketServer(PORT,host='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)
print("启动成功")
server.run_forever()
