For example, you might want to write code for a service that starts up and runs forever, accepting service requests.Forever, in this context, means until you shut it down. The typical way to write an infinite loop is to use thewhile Trueconstruct. To ensure that the loop terminates natura...
self.loop 创建了一个新的异步事件循环。 run 方法: 这个方法是线程的入口点,它设置当前线程的事件循环,并打开输出文件。 self.loop.run_forever() 使事件循环持续运行,直到调用 stop 方法。 最后,通过 self.loop.run_until_complete(asyncio.sleep(0)) 确保事件循环能够完成所有挂起的协程。 异步写入方法 real...
