异步协程开发技巧：实现高并发的短链接生成器

import aiohttp
import asyncio

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

            task = asyncio.ensure_future(fetch(session, url))
            tasks.append(task)
        responses = await asyncio.gather(*tasks)
        print(responses)

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())
