مشاكل CORS في طلب تسجيل الخروج لتطبيق الويب

Hey everyone, thanks for Discourse I’ve find it pretty easy to set up, up until this point.

I have a SSO setup that works fine with my web app, however when I trigger the admin/users/:id/logout endpoint, it won’t work from the web app.

For some reason it’ll accept a cURL just fine:

 curl 'http://localhost/admin/users/2/log_out' \
  -X 'POST' \
  -H 'Api-Key: <>' \
  -H 'Content-Type: multipart/form-data;' -v

*   Trying 127.0.0.1:80...
* Connected to localho.st (127.0.0.1) port 80 (#0)
> POST /admin/users/2/log_out HTTP/1.1
> Host: localho.st
> User-Agent: curl/7.77.0
> Accept: */*
> Api-Key: <>
> Content-Type: multipart/form-data;
>
* Mark bundle as not supporting multiuse

{"success":"OK"}

and the server logs:

Started POST "/admin/users/2/log_out" for 172.18.0.1 at 2021-11-30 21:12:58 +0000
Processing by Admin::UsersController#log_out as */*
  Parameters: {"user_id"=>"2"}
Can't verify CSRF token authenticity.
Completed 200 OK in 75ms (Views: 0.9ms | ActiveRecord: 0.0ms | Allocations: 2350)

But then when I try from the web app:

axios.post('http://localhost/admin/users/2/log_out', {}, {
  headers: {
    'User-Api-Key': '<>',
    'Content-Type': 'multipart/form-data'
  }
});

the server logs show:

Started POST "/admin/users/2/log_out" for 172.18.0.1 at 2021-11-30 21:08:26 +0000
ActionController::RoutingError (No route matches [POST] "/admin/users/2/log_out")

some more evidence:

What do you mean by “from the webapp”. Are you trying to call this API endpoint from front-end javascript? That would expose the admin API key.

That’s right, wanted to verify first in the front-end, but if you recommend setting up an endpoint on my server to handle the logout (and there is no shorter path around it) I’ll follow your advice.
