python使用协程循环并发执行http请求

import asyncio
import aiohttp

async def do_request(val):
    timeout = aiohttp.ClientTimeout(total=86400)
    async with aiohttp.ClientSession(timeout=timeout) as session:
        async with session.post('http://127.0.0.1:5000'), json={"val": val}) as resp:
        result = await resp.json()
        return result

    async def main(count):
        tasks = [do_request(val) from val in range(count)]
        values = await asyncio.gather(*tasks)
        print(values)

asyncio.run(main(10))
