tornado 执行 asyncio 异步报错 run_forever assert self._self_reading_future is None

报错信息：python38\lib\asyncio\windows_events.py", line 314 run_forever  assert self._self_reading_future is None

解决如下：

需要引入nest_asyncio，代码如下：

import nest_asyncio

nest_asyncio.apply()

封装执行多个异步方法并返回结果​

import asyncio
import nest_asyncio
from tornado.platform.asyncio import to_asyncio_future

nest_asyncio.apply()

async def asyncio_all_task(*fuc_list):
    '''
    执行多个异步方法
    '''
    tasks=[]
    for t in fuc_list:
        tasks.append(asyncio.ensure_future(t))
    
    result= asyncio.get_event_loop().run_until_complete(to_asyncio_future(asyncio.gather(*tasks)))
    # asyncio.get_event_loop().run_until_complete(asyncio.wait(tasks))
    return  result

def asyncio_all_task2(*fuc_list):
    result=[]
    loop = asyncio.get_event_loop()
    res= loop.run_until_complete(asyncio.wait(fuc_list))
    for r in res[0]:
        result.append(r._result)

    return result
