fastapi add_event_handler 连接mysql fastapi django 天下武功,唯快不破。在软件开发中更是如此,“快”能从多方面提升用户体验。谈到Python,它似乎天生就和速度无关,你可能很熟悉Django、Flask这些框架,虽然开发效率的确不错,但是速度就一言难尽。那么在前后端分离开发的时代,有没有能拿得出手的Python Web框架呢?当...

有时候, 我们希望在服务启动时进行一些操作, 比如初始化数据库连接池等操作, 原来我们可能是直接写在生成 app 的时候, 而在服务关闭时关闭连接池则需要费些心思, FastApi提供了事件, 我们注册到某个事件后其在指定的时候执行我们注册的功能, 还拿 main.py 举例 add_event_handler 代表添加事件, 参数1为事件的名...

How can I register startup/shutdown handlers for the sub app? All solutions I could find either require control over thelifespangenerator (which I don't have) or involve deprecated methods likeadd_event_handler(which doesn't work whenlifespanis set). ...

如果你写的都是同步的 handler,无非就是性能退化到和 Flask 一样呗,但是自动生成的 swagger UI 和类型检查还是有的呀,这俩还不够香么?FastAPI 的作者也在一个播客访谈中谈过,asyncio 的生态肯定是还不够丰富的,所以你完全可以把大多数的函数写成同步的,找到个别 QPS 特别高的函数协程异步的,这样兼顾了开发效率...
