how to control limit by duration? about slowapi

Sounds like you want to set a limit of 1/30seconds with a moving-window strategy:

limiter = Limiter(..., strategy="moving-window")

@limiter.limit("1/30seconds")
async def foo(request: Request)
    pass

Note that I haven't tested this code, there could be bugs. Let me know if this works for you.

For more info, check limits's docs on rate-limit-string-notation.

@laurentS Maybe there should be docs to describe the different supported strategies?

[laurentS]

The different strategies are documented in limits docs. Do you think we should duplicate this, or just point to it?

okay, I got it. Thanks for all. And I think it is better to write down some strategies for beginners.

[nootr]

The strategies are documented, but I was thinking about the string values of the strategies (fixed-window, fixed-window-elastic-expiry, moving-window). These aren't mentioned in the limits docs, except in the source code.

Maybe we could cross-reference to limits.strategies.STRATEGIES in the docstrings?
