在python中使用aiohttp获取多个urls

import asyncio
import aiohttp

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def get_multiple_urls(urls):
    async with aiohttp.ClientSession() as session:
        tasks = []
        for url in urls:
            task = asyncio.ensure_future(fetch(session, url))
            tasks.append(task)
        responses = await asyncio.gather(*tasks)
        return responses

urls = ['http://example.com', 'http://example.org', 'http://example.net']
loop = asyncio.get_event_loop()
results = loop.run_until_complete(get_multiple_urls(urls))
