描述

The IPFS api is nice and simple, but can cause problems for people wanting to use it as a gateway to serve images. A request for the wrong hash could cause ipfsd to start fetching a ton of data that is not actually desired.

The solutions I have at the moment are to do ipfs file ls first and then fetch, but that requires me to set up my own middleware when it would be nice to have the daemon fetch it for me.

研究方向
Investigate the current file fetching mechanism in the IPFS daemon, specifically in the gateway handler (likely in `core/commands/` or `gateway/` directories). Review the `ipfs file ls` command to understand how to get file size before fetching. Consider implementing a flag like ` max size` in the `ipfs cat` or gateway endpoint to limit response size. Look at existing PRs or discussions for prior attempts.
