Python server aiohttp web test24.11.17

to test this asynchron web server you need to use a client what allows to make multiple request to the same url like curl 
firefox wont' allow you to make concurrent requests to the same URL

#!/usr/bin/env python3
from aiohttp import web
import time
import asyncio
import random
import string
import logging

logger = logging.getLogger('webserver')
logger.setLevel(logging.INFO)
handler = logging.StreamHandler()
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)

def randomword(length):
  return ''.join(random.choice(string.ascii_lowercase) for i in range(length))

async def hello(request):
  sleeptime = 10 # seconds
  requestid = randomword(5)
  logger.info("Request id: {} received - will sleep for {}".format(requestid, sleeptime))
  await asyncio.sleep(sleeptime)
  logger.info("Request id: {} wakeup and respond".format(requestid))
  return web.json_response()

# create app and register with request handler
app = web.Application()
app.router.add_get('/', hello)
web.run_app(app)
