API を 1000 回要求する (ネットワーク要求を送信して応答を処理する) 場合、最初に 1000 個の要求をすべて送信した後に応答の処理を開始し、次に応答を処理します。
asyncio が完了したら、await 位置コードを返すように指示できますか?
import asyncio
import httpx
# request_time = 10
request_time = 1000 # large enough to ensure previous responses return
limits = httpx.Limits(max_connections=5)
client = httpx.AsyncClient(limits=limits)
async def request_baidu(i):
# async with httpx.AsyncClient(limits=limits) as client:
print(f"===> %d" % i)
r = await client.get("http://www.baidu.com")
# print(r.status_code)
print(f"<=== %d" % i) # How to ensure return to run this code, not make a new request (run a new task `request_baidu` here)
async def main():
request_list = [asyncio.create_task(request_baidu(i)) for i in range(request_time)]
await asyncio.gather(*request_list)
if __name__ == '__main__':
asyncio.run(main())
結果
# request_time = 10
