help request: How to get the context (ctx) or request headers inside the ResponseFilter of a Go plugin?

[BainDragneel]

Description

I need to add some information to the response header, and the added information depends on values from the request header. I’m considering using context to pass data, but I couldn’t find a function to get the ctx.

Environment

• APISIX version (run apisix version): v3.11

Are you using apisix-go-plugin-runner?

[BainDragneel]

YES，The plugin is written in Go and is injected into the conf of the ext-plugin-post-resp plugin.

@Baoyuantop Please take another look at this issue.

You can refer to this document https://apisix.apache.org/docs/go-plugin-runner/getting-started/
In addition, this plugin for APISIX provides a similar capability.

@Baoyuantop The values I need to add depend on the request endpoint and certain request headers. For example, whitelisted endpoints don’t require this header to be added.
