如何从Flask服务器发送多个请求？

import threading
import requests

def send_request(url):
    response = requests.get(url)
    print(response.text)

urls = ['http://example.com', 'http://example.org', 'http://example.net']

threads = []
for url in urls:
    t = threading.Thread(target=send_request, args=(url,))
    threads.append(t)
    t.start()

for t in threads:
    t.join()

import asyncio
import aiohttp

async def send_request(url):
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            return await response.text()

async def main():
    urls = ['http://example.com', 'http://example.org', 'http://example.net']
    tasks = [send_request(url) for url in urls]
    responses = await asyncio.gather(*tasks)
    for response in responses:
        print(response)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())
