Metadata-Version: 1.0 Name: SimpleWebSocketServer Version: 0.1.0 Summary: A Simple Websocket Server written in Python Home-page: https://github.com/dpallot/simple-websocket-server/ Author: Dave Author-email: UNKNOWN License: UNKNOWN Description: ## A Simple Websocket Server written in Python - RFC 6455 (All latest browsers) - TLS/SSL out of the box - Passes Autobahns Websocket Testsuite - Support for Python 2 and 3 #### Installation You can install SimpleWebSocketServer by running the following command... `sudo pip install git+https://github.com/dpallot/simple-websocket-server.git` Or by downloading the repository and running `sudo python setup.py install`. Installation via pip is suggested. #### Echo Server Example `````python from SimpleWebSocketServer import SimpleWebSocketServer, WebSocket class SimpleEcho(WebSocket): def handleMessage(self): # echo message back to client self.sendMessage(self.data) def handleConnected(self): print self.address, 'connected' def handleClose(self): print self.address, 'closed' server = SimpleWebSocketServer('', 8000, SimpleEcho) server.serveforever() ````` Open *websocket.html* and connect to the server. #### Chat Server Example `````python from SimpleWebSocketServer import SimpleWebSocketServer, WebSocket clients = [] class SimpleChat(WebSocket): def handleMessage(self): for client in clients: if client != self: client.sendMessage(self.address[0] + u' - ' + self.data) def handleConnected(self): print self.address, 'connected' for client in clients: client.sendMessage(self.address[0] + u' - connected') clients.append(self) def handleClose(self): clients.remove(self) print self.address, 'closed' for client in clients: client.sendMessage(self.address[0] + u' - disconnected') server = SimpleWebSocketServer('', 8000, SimpleChat) server.serveforever() ````` Open multiple *websocket.html* and connect to the server. #### Want to get up and running faster? There is an example which provides a simple echo and chat server Echo Server python SimpleExampleServer.py --example echo Chat Server (open up multiple *websocket.html* files) python SimpleExampleServer.py --example chat #### TLS/SSL Example 1) Generate a certificate with key openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout cert.pem 2) Run the secure TSL/SSL server (in this case the cert.pem file is in the same directory) python SimpleExampleServer.py --example chat --ssl 1 --cert ./cert.pem 3) Offer the certificate to the browser by serving *websocket.html* through https. The HTTPS server will look for cert.pem in the local directory. Ensure the *websocket.html* is also in the same directory to where the server is run. sudo python SimpleHTTPSServer.py 4) Open a web browser to: *https://localhost:443/websocket.html* 5) Change *ws://localhost:8000/* to *wss://localhost:8000* and click connect. Note: if you are having problems connecting, ensure that the certificate is added in your browser against the exception *https://localhost:8000* or whatever host:port pair you want to connect to. #### For the Programmers handleConnected: called when handshake is complete - self.address: TCP address port tuple of the endpoint handleClose: called when the endpoint is closed or there is an error handleMessage: gets called when there is an incoming message from the client endpoint - self.opcode: the WebSocket frame type (STREAM, TEXT, BINARY) - self.data: bytearray (BINARY frame) or unicode string payload (TEXT frame) - self.request: HTTP details from the WebSocket handshake (refer to BaseHTTPRequestHandler) sendMessage: send some text or binary data to the client endpoint - sending data as a unicode object will send a TEXT frame - sending data as a bytearray object will send a BINARY frame sendClose: send close frame to endpoint --------------------- The MIT License (MIT) Platform: UNKNOWN
