Re-explain
Path parameters are defined in the function signature with type hints:
from fastapi import FastAPI, Path
app = FastAPI()
@app.get("/items/{item_id}")
def get_item(
item_id: int = Path(..., gt=0, description="The ID of the item")
):
return {"item_id": item_id}
@app.get("/users/{user_id}/items/{item_id}")
def get_user_item(user_id: int, item_id: int):
return {"user_id": user_id, "item_id": item_id}
