Python requests及aiohttp速度对比代码实例_Python

环境：centos7 python3.6

测试网址：www.bai.com

测试方式：抓取百度100次

结果：

aio: 10.702147483825684s
requests: 12.404678583145142s

异步框架的速度还是有显著提升的。

下面贡献代码：

									import aiohttp

									import time

									import requests

									import asyncio

									def test_requests():

									  """ 测试requessts请求百度100次时间 """

									  start = time.time()

									  url = "https://www.baidu.com"

									  for i in range(100):

									    requests.get(url)

									  end = time.time()

									  print("requests:")

									  print( end - start )

									async def aio_download(url):

									  """ aiohttp 下载 """

									  async with aiohttp.ClientSession() as session:

									    await session.get(url)

									async def test_aio():

									  """ 测试aiohtpp请求百度100次时间 """

									  url = "https://www.baidu.com"

									  start = time.time()

									  for i in range(100):

									    await aio_download(url)

									  end = time.time()

									  print("aio: ")

									  print( end - start )

									if __name__ == "__main__":

									  loop = asyncio.get_event_loop()

									  loop.run_until_complete(test_aio())

									  test_requests()
