Include headers in cached requests

[524c]

Hey guys.

I have a project that depends on a header included in the responses of an action. I need to enable a cache for these actions and would like to use Moleculer's native cache feature, but I noticed that Moleculer cache only the response without including the headers.

Is there any option to include the response headers in the cache?

You can define response headers inside the action via ctx.meta.$responseHeaders. More info: https://moleculer.services/docs/0.14/moleculer-web#Response-type-amp-status-code

@icebob Thank you very much. Where is the best place for me to make a donation? (it will be symbolic, but it's a way to recognize the great project you've developed, from one developer to another).

You're welcome.
For donation, you can use Github Sponsors or Open Collective. Thanks in advance!

Yes, I'm using the meta to add headers as responses (0.14). What I noticed is that when caching is enabled, these custom headers are not saved along with the body.

Yes, you are right. Plz open an issue about it, however, I won't able to fix it, just with breaking changes because need to change the whole cache storage mechanism, but I will able to do it in later versions.

For a workaround, if you split your action to separated action, and the first one is not cached, just calls the second one and put the headers, and the second one is cached and do the logic.

great, thanks!

I opened a issue: #1242

Or you can use hook onAfterCall in the API gateway
