在Python的ASGI(Asynchronous Server Gateway Interface)应用程序中,遇到“exception in asgi application”错误通常表明在异步处理过程中发生了异常。下面我将从理解ASGI、异常类型、可能原因、解决方法及预防措施几个方面进行详细解答。 1. 理解ASGI及其在Python中的应用 ASGI是Python的一个标准,用于构建异步Web应用和服务...

在ASGI标准下,python-web-app需要这样的接口实现: asyncdefapplication(scope,receive,send):"""python-web-app应用层实现:param scope: 由python-web-server提供,表示当前连接的环境信息:param receive: 通过这个协程,可以收到由python-web-server发来的事件:param send: 通过这个协程,可以写回事件给python-web-ser...

在Application 运行后,lifespan 会率先执行。它是 ASGI 提供的生命周期 hooks,可用于在 Application 启动和关闭时执行一些操作。 以下是一个简单的示例: asyncdefstartup():# 回调函数,在服务启动时print("Startup ...")asyncdefshutdown():# 回调函数,在服务关闭时print("Shutdown ...")asyncdefapp(scope,...
