FastAPI - Middleware and Hooks
You want to add middleware that logs request time but only for routes under /api. Why does FastAPI middleware still run on all routes, and how can you limit it?
AFastAPI does not support middleware; use dependencies instead
BMiddleware can be added only to specific routes by passing route list to add_middleware
CMiddleware runs globally but can be disabled per route with a decorator
DMiddleware runs globally by design; to limit, check path inside middleware and skip non-/api requests
Step-by-Step Solution
Solution:
Step 1: Understand middleware scope
FastAPI middleware always runs globally on every request to handle shared tasks.
Step 2: Limit middleware effect by path check
To restrict middleware to /api routes, check the request URL path inside middleware and skip processing for others.
Final Answer:
Middleware runs globally by design; to limit, check path inside middleware and skip non-/api requests -> Option D
