描述

I have BloomSize set to 1048576, if I then try to do any config call, example

ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'

I get:

Error: failed to set config value: Failure to decode config: json: cannot unmarshal number 1.048576e+06 into Go value of type int (maybe use --json?)

The integer is being transformed into floating point at some point.

研究方向
Investigate the config package in the IPFS Go repository, specifically how config values are read and written. The issue occurs because large integers (e.g., 1048576) are being serialized in Go's default JSON marshaler using scientific notation (1.048576e+06), which then fails to unmarshal into an int type. Look at the config structs and how they handle numeric fields. Consider using json.Number or implementing a custom unmarshaler to preserve integer precision. Check comments in the issue for any pointers, and search for similar fixes in the codebase.
