最简单的方法是使用现有的“轮子”,比如asgiref.async_to_sync from asgiref.sync import async_to_sync 然后: async_to_sync(main)() 一般来说: async_to_sync(<your_async_func>)(<.. arguments for async function ..>) 这是一个调用者类,它将仅在具有事件循环的线程上工作的可等待对象转变为在子线...

Of course, you can run a coroutine withasyncio.run(), and blocking sync code from a coroutine withasyncio.to_thread(), but the former isn't granular enough, and the latter doesn't solve async code being at the top. As always, there must be a better way. ...
每次协程函数创建返回值后,就暂停(即init_suspend),接着在暂停实现里面,就发送task的run,run里面实现resume。主要是main函数不能执行协程。让event loop取出run执行协程。 在co_wait时,重载了运算符,也执行子协程的 suspend,在暂停实现中:记录了父协程,供调试。然后将自己恢复执行。

This function cannot be called when another asyncio event loop is running in the same thread. If debug is True, the event loop will be run in debug mode. This function always creates a new event loop and closes it at the end.
