Pywss - implement WebSocket server with python

WebSocket-Server server-side framework for the development of similar Flask for python3.X

1, the mounting module Pywss

pip install pywss

2, set up makeshift server

2.1 server code

Code Description

• route: Registration request path
• example_1(request, data):
  • request: Socket handle connected can transmit and receive data. Transmit data request.ws.send(data), receive datarequest.ws_recv(1024)
  • data: Data sent by a client is stored in here

from pywss import Pyws, route

@route('/test/example/1')
def example_1(request, data):
    return data + ' - data from pywss'

if __name__ == '__main__':
    ws = Pyws(__name__, address='127.0.0.1', port=8866)
    ws.serve_forever()

2.2 client code

Client code, it is recommended to run directly in the browser, eg: Chorme Open a new tab -> F12 -> console
Introduction Code

• WebSocket(ws_url): Initiation Protocol upgraded to a WebSocket connection request, ws_url do wrong path slightly to the server in route()association with the registered path
• ws.onmessage: When data transfer over, will perform this function
• ws.onclose: When disconnecting, you will perform this function
• ws.onopen: When the connection is established, it will perform this function

ws = new WebSocket("ws://127.0.0.1:8866/test/example/1");
ws.onmessage = function (ev) {
    console.log(JSON.parse(ev.data));
}
ws.onclose = function (ev) {
    console.log('Connect Closed')
}
ws.onopen = function() {
    if (ws.readyState === WebSocket.OPEN) {
        ws.send('hello, pywss!')  // you will get 'hello, pywss! - data from pywss'
    }
}
