Pythonの3 aiohttp |サーバーの応答時間を最適化する

Question

from aiohttp import web 
from aiohttp import ClientSession 

# this would go in a different file but keep it simple for now 
class Generate: 

    # Get a person object from my website 
    async def get_person(self): 
     async with ClientSession() as session: 
      async with session.get('http://surveycodebot.com/person/generate') as response: 
       resp = await response.json() 
       # this prints the person 
       print(resp) 
       return resp 

    # loops `get_person` to get more than 1 person 
    async def get_people(self): 
     # array for gathering all responses 
     for _ in range(0,10): 
      resp = await self.get_person() 
     return resp 

# class to handle '/' 
class HomePage(web.View): 
    async def get(self): 
     # initiate the Generate class and call get_people 
     await Generate().get_people() 
     return web.Response(text="Hello, world") 

if __name__ == "__main__": 
    app = web.Application() 
    app.router.add_get('/', HomePage) 
    web.run_app(app) 

コードが正常に動作しています。 HomePageの読み込みに時間がかかり、なぜ私は思っていました。私は28行目の利回りを使うべきだと思っていますが、私がそれを行うときには限界があります。ありがとう。

aiohttp on_startupシグナルを使用して、複数のクライアント要求の間でセッションを共有することで、最適化することができます。次のような

何かが行います。

import asyncio 
from aiohttp import web 
from aiohttp import ClientSession 


class Generate: 

    def __init__(self, session): 
     self.session = session 

    # Get a person object from my website 
    async def get_person(self): 
     async with self.session.get('http://surveycodebot.com/person/generate') as response: 
      resp = await response.json() 
      # this prints the person 
      print(resp) 
      return resp 

    # loops `get_person` to get more than 1 person 
    async def get_people(self): 
     # array for gathering all responses 
     for _ in range(0,10): 
      resp = await self.get_person() 
     return resp 

# class to handle '/' 
class HomePage(web.View): 
    async def get(self): 
     # initiate the Generate class and call get_people 
     await app['generate'].get_people() 
     return web.Response(text="Hello, world") 


async def on_startup(app): 
    session = ClientSession() 
    app['generate'] = Generate(session) 



if __name__ == "__main__": 
    app = web.Application() 
    app.router.add_get('/', HomePage) 
    app.on_startup.append(on_startup) 
    web.run_app(app)
