SockJS server implementation for aiohttp.
Project description
sockjs is a SockJS integration for aiohttp. SockJS interface is implemented as a aiohttp route. Its possible to create any number of different sockjs routes, ie /sockjs/* or /mycustom-sockjs/*. You can provide different session implementation and management for each sockjs route.
Simple aiohttp web server is required:
[server:main] use = egg:gunicorn#main host = 0.0.0.0 port = 8080 worker = aiohttp.worker.GunicornWebWorker
Example of sockjs route:
def main(global_settings, **settings):
app = web.Application()
app.router.add_route('GET', '/', index)
sockjs.add_endpoint(app, prefix='/sockjs', handler=chatSession)
web.run_app(app)
Client side code:
<script src="https://cdn.jsdelivr.net/npm/sockjs-client@1/dist/sockjs.min.js"></script>
<script>
var sock = new SockJS('http://localhost:8080/sockjs');
sock.onopen = function() {
console.log('open');
sock.send('test');
};
sock.onmessage = function(e) {
console.log('message', e.data);
sock.close();
};
sock.onclose = function() {
console.log('close');
};
</script>
