python怎么并发上千个请求

import threading
import requests

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

urls = [...]# 存储要发送请求的URL列表

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

for thread in threads:
thread.join()

import asyncio
import aiohttp

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

urls = [...]# 存储要发送请求的URL列表

loop = asyncio.get_event_loop()
tasks = [send_request(url) for url in urls]
loop.run_until_complete(asyncio.wait(tasks))
loop.close()

import grequests

urls = [...]# 存储要发送请求的URL列表

requests = [grequests.get(url) for url in urls]
responses = grequests.map(requests)

for response in responses:
print(response.text)

import gevent
import requests

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

urls = [...]# 存储要发送请求的URL列表

greenlets = [gevent.spawn(send_request, url) for url in urls]
gevent.joinall(greenlets)
