How to add Run Nested applications in AioHttp - aiohttp

Question

I am trying out nested application in AIOhttp but can't get it to run.
If I want my url to be like localhost/greet/ and localhost/greet/abc, I am using the following code but giving me 404 Not Found so my routing is not correct.
I am not able to find much online resources here as well.
Below is my code:
app = web.Application()
greet = web.Application()
app.router.add_get('/', index)
greet.router.add_get('/{name}', handle_name, name='name')
app.add_subapp('/greet/', greet)
web.run_app(app, host='127.0.0.1', port=8080)
async def handle_name(request):
name = request.match_info.get('name', "Anonymous")
txt = "Hello {}".format(name)
return web.Response(text=txt)
Any guidance will be helpful!

Not entirely clear what your problem was, but this works fine:
from aiohttp import web
async def index_view(request):
return web.Response(text='index\n')
async def subapp_view(request):
name = request.match_info.get('name', "Anonymous")
txt = "Hello {}\n".format(name)
return web.Response(text=txt)
app = web.Application()
app.router.add_get('/', index_view)
greet = web.Application()
greet.router.add_get('/{name}', subapp_view)
app.add_subapp('/greet/', greet)
if __name__ == '__main__':
web.run_app(app, host='127.0.0.1', port=8080)
and then testing with curl:
~ 0 25ms ➤ curl localhost:8080/
index
~ 0 33ms ➤ curl localhost:8080/greet/world
Hello world
Hope that answers your question.
