Debug mode of asyncio 我们用asyncio就是为了提高性能,而为了更容易去开发编写异步的代码,我们需要开启debug模式 在应用中开启调试模式: 全局开启异步的调试模式,可以通过设置环境变量PYTHONASYNCIODEBUG=1,或者直接调用AbstractEventLoop.set_debug() 设置asynico logger的日志等级为DEBUG,如在代码开头logging.basicConfig(l...

Queue 队列，用于管理并行任务，确保执行顺序，通过 asyncio.Queue 管理任务队列，使用 queue.put_nowait、queue.get()、queue.task_done()、queue.join() 操作。使用 debug mode，asyncio.run(coroutine(), debug=True)，当协程或任务运行时间超过 100 毫秒时，可获取有用日志信息。
