aiohttp安装:pip install aiohttp。在本地程序通过aiohttp进行http请求简单代码如下: import aiohttp import asyncio import async_timeout async def fetch(session, url): with async_timeout.timeout(10): async with session.get(url) as response:

Event loop is closed 场景:协程创建时,会时不时报错RuntimeError: Event loop is closed 报错原因: aiohttp 内部使用了 _ProactorBasePipeTransport ,程序退出释放内存时自动调用其del方法导致二次关闭事件循环。一般的协程程序是不会使用_ProactorBasePipeTransport 的,所以asyncio.run() 还是可以正常运行。而且这种情况...
