使用aiohttp进行Python异步函数调用

我想更好地了解aiohttp。有人可以检查为什么我的代码没有打印请求的响应，而是只打印协程。

import asyncio
import aiohttp
import requests

async def get_event_1(session):
    url = "https://stackoverflow.com/"
    headers = {
        'content-Type': 'application/json'
    }
    response = await session.request('GET',url)
    return response.json()

async def get_event_2(session):
    url = "https://google.com"
    headers = {
        'content-Type': 'application/json'
    }
    response = await session.request('GET',url)
    return response.json()

async def main():
    async with aiohttp.ClientSession() as session:
        return await asyncio.gather(
            get_event_1(session),get_event_2(session)
        )

loop = asyncio.get_event_loop()
x = loop.run_until_complete(main())
loop.close()
print(x)

输出：

$ python async.py 
[<coroutine object ClientResponse.json at 0x10567ae60>,<coroutine object ClientResponse.json at 0x10567aef0>]
sys:1: RuntimeWarning: coroutine 'ClientResponse.json' was never awaited

我该如何打印回复？
