Hello, sur la video autour de asyncio, vous utilisez python 2.7.12. J'utilise python 3.10, aussi je souhaite faire partager mon code (qui fonctionne) selon ma vision et compréhension sur le sujet d'étude que vous avez proposé. Yvan Vogel.
#CODE en python 3.10.0 64 bits (VScode 1.62.3)
import datetime
import asyncio

# ----------------------------------------------------------------------------------------------------------------------------
def req_bloquante(num):
print(f"Get {num}")
uid = requests.get("https://httpbin.org/uuid").json()["uuid"]
print(f"Res {num}: {uid}")
def faire_toutes_les_requetes():
for x in range(51):
req_bloquante(x)
print("=====> ### Bloquant : ")
start = datetime.datetime.now()
faire_toutes_les_requetes()
exec_time = (datetime.datetime.now() - start).seconds
print(f"Downloading all take {exec_time} seconds\n")
# ----------------------------------------------------------------------------------------------------------------------------
async def requeteSansBloquer(semaphore, num, session):
print(f"Get {num}")
# await semaphore.acquire() # putting this await semaphore commande the Res is ordering but process very slow ~60 sec
async with session.get("https://httpbin.org/uuid") as response:
uid = (await response.json())["uuid"]
# await asyncio.sleep(delay=3) #delay = number of seconds
# semaphore.release()
print(f"Res {num}: {uid}")
# return uid # ?
async def main():
semaphore = asyncio.Semaphore(value=1)
tasks = []
async with aiohttp.ClientSession(
loop=loop, connector=aiohttp.TCPConnector(ssl=False)
) as session:
for x in range(51):
tasks.append(requeteSansBloquer(semaphore, x, session))
await asyncio.gather(*tasks)
print("This is after the loop...")
if __name__ == "__main__":
print("=====> ### Non Bloquant : ")
start = datetime.datetime.now()
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
exec_time = (datetime.datetime.now() - start).microseconds
print(f"Downloading all take {exec_time} micro seconds\n")
