中间件影响 API 上的所有请求

Question

I'm working with fastapi and suppose I have registered 2 middlewares called A and B (for example, they can add to each request the connection to a database) . Suppose also that I have 2 endpoints, and the first one only need A middleware and the second one only need B middleware. I used dependencies to establish the needs of each endpoint . When I use the first endpoint, the request is equiped with the result of both middlewares A and B, I want to restrict the effect of middlewares only when they are needed, I thought that was done using dependencies. How can I do that?. Thank you!!

如果我正确理解您的问题，该实践似乎要么在您的中间件中创建自定义逻辑（例如检查调用了哪个路径/路由），要么使用文档中描述的声明自定义 Request/APIRoute 对象的高级功能
