python aiohttp into existing event loop
I'm testing aiohttp and asyncio. I want the same event loop to have a socket, http server, http client.
I'm using this sample code:
@routes.get('/')
async def hello(request):
return web.Response(text="Hello, world")
app = web.Application()
app.add_routes(routes)
web.run_app(app)
The problem is run_app
is blocking. I want to add the http server into an existing event loop, that I create using:
asyncio.get_event_loop()
python python-asyncio aiohttp

The problem is
run_app
is blocking. I want to add the http server into an existing event loop
run_app
is just a convenience API. To hook into an existing event loop, you can directly instantiate the AppRunner
:
loop = asyncio.get_event_loop()
# add stuff to the loop
...
# set up aiohttp - like run_app, but non-blocking
runner = aiohttp.web.AppRunner(app)
loop.run_until_complete(runner.setup())
site = aiohttp.web.TCPSite(runner)
loop.run_until_complete(site.start())
# add more stuff to the loop
...
loop.run_forever()
Thanks, any reason why the server wont terminate on SIGINT (pressing CTRL+C)? I'm using windows powershell
