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P

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...
sleep(1) except Exception: exit(0) if __name__ == "__main__": sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) sock.bind(("127.0.0.1", 10083)) sock.listen(5) t = threading.Thread(target=handler_accept(sock)) ...
Thus, we have asgiref.sync.async_to_sync. This handy wrapper will do all of the above, plus exception and return value propagation, plus detecting if you do something stupid (like trying to use it from a thread that already has an event loop running in it). All you need to do is ...
