【python爬虫】aiohttp模块的异步协程代码模板

aiohttp模块的使用：

import aiohttp
import asynciourls = ["","",""
]async def download(url):name = url.rsplit("/",1)[1]#发送请求async with aiohttp.ClientSession() as session:async with session.get(url) as resp:with open(name, mode="wb") as f:f.write(await resp.content.read())  #读取内容为异步的，需要await挂起print(name,"done!")async def main():tasks = []for url in urls:tasks.append(download(url))await asyncio.wait(tasks)if __name__ == '__main__':asyncio.run(main())
