How to enable CORS?

[Daniel.]

Hi everybody,
I have some code that runs as a cockpit plugin. I have a lot of calls to
cockpit.spawn, which I want to replace by fetch calls. The problem is that
the software running API is running on port 443, not 9090, so I get a big
and red error message about CORS not enabled,

I can check that response has Acces-Control-Allow-Origin set to
mymachine:9090, in dev tools

I did some googling and found that I would enable CORS by editing
cockpit.conf and placing a `Origin = https://mymachine:9090
wss://mymachine:9090 https://mymachine%60 I tried that without success. I may
be wrong here

I'm running a Centos7 machine with cockpit 195, here is the content of my
/etc/cockpit/cockpit.conf

[WebService]
Origin = https://192.168.123.2:9090 wss://192.168.123.2:9090
http://192.168.123.2 https://192.168.123.2

Any ideas?

Best regards

Perhaps you could use cockpit.http() to avoid CORS problems:

https://cockpit-project.org/guide/latest/cockpit-http.html

This means the HTTP calls go through the server Cockpit is running on,
than directly from the browser. That should avoid CORS problems.

Cheers,

Hi Stef,

Thanks for the response .. that may work for me, but I want to remove some
code from cockpit plugin and if is already decoupled it would be much easier

Does cockpit support it? From the documentation it seems too but I can't
get it working

Regards
