Python 并发 http 编程 ⭐️

asyncio

使用 requests_async 库（一个支持异步的 HTTP 库）进行异步网络请求：

import requests_async as requests
 
async def main(args):
    # 你可以通过这种方式获取url
    url = args.params['url']
    # 使用await，这将异步等待网络请求的完成
    response = await requests.get(url)
 
    ret = {
        'code': response.status_code,
        'res': response.text,
    }
    return ret

aiohttp

import aiohttp
import asyncio
 
async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()
 
async def main():
    async with aiohttp.ClientSession() as session:
        html = await fetch(session, 'http://python.org')
        print(html)
 
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
