django - Uvicorn 自动关闭
问题描述
尝试在共享主机服务器（Linux Debian）上启动 uvicorn：
uvicorn etebase_server.asgi:application --port 8000 --host 0.0.0.0 --lifespan on
uvicorn 启动，可以处理几个 HTTP GET，但在 30 秒左右后关闭。这是错误消息：
INFO: Started server process [125907]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
INFO: Shutting down
INFO: Waiting for application shutdown.

有什么想法AttributeError: 'RedisWrapper' object has no attribute 'redis'吗？？？
