Query Parameters #
Besides
Extra Parameters (width, height, and related options), WebP Server Go supports metadata query parameters on image requests.
meta=full
#
Request full metadata for a resource as JSON:
GET /path/to/image.jpg?meta=full
Behavior:
| Condition | HTTP status |
|---|---|
| Valid path and source exists (local file or reachable remote) | 200 with JSON body |
| Malformed or illegal path | 404 Not Found |
| Valid path but source does not exist | 404 Not Found |
Previously, meta=full could return metadata from cache even when the source file was missing or the path was invalid. Current versions validate the path and confirm the source exists before returning metadata.
For path validation and status code policy, see Security.
