Android使用Websocket实现聊天室
autobahn.twisted.websocket是一个Python库,它提供了在Twisted框架下使用WebSocket的功能。使用autobahn.twisted.websocket,你可以轻松地创建WebSocket客户端和服务器,以实现实时通信。下面是一个简单的例子,演示如何使用autobahn.twisted.websocket创建一个WebSocket服务器:
```python
from twisted.internet import reactor
from autobahn.twisted.websocket import WebSocketServerFactory, \
WebSocketServerProtocol
class MyServerProtocol(WebSocketServerProtocol):
def onConnect(self, request):
print("Client connected: {0}".format(request.peer))
def onOpen(self):
print("WebSocket connection open.")
def onMessage(self, payload, isBinary):
if isBinary:
print("Binary message received: {0} bytes".format(len(payload)))
else:
print("Text message received: {0}".format(payload.decode('utf8')))
# echo message back to client
self.sendMessage(payload, isBinary)
def onClose(self, wasClean, code, reason):
print("WebSocket connection closed: {0}".format(reason))
if __name__ == '__main__':
factory = WebSocketServerFactory("ws://localhost:9000")
factory.protocol = MyServerProtocol
reactor.listenTCP(9000, factory)
reactor.run()
```
这个例子创建了一个WebSocket服务器,监听在本地的9000端口。当客户端连接时,会打印出相应的信息。当收到消息时,会将其原封不动地发送回客户端。当客户端断开连接时,同样会打印出相应的信息。
