Getting response from a RESTful Go service

Elastic Stack Kibana
1

Hi Community.
So, i have been trying to request from my Go service using Ajax/fetch with the kibana plugin Js file but so far no luck. I get a 405 (method not allowed) error.

request:
fetch('https://somelink/createinfo', { mode: 'no-cors'}, { headers: { 'Content-Type': 'application/json' }, method: "POST", body: jsonsjson }) .then(res => res.text()) .then(console.log)

On Go service I have added the following header.

w.Header().Set("Access-Control-Allow-Origin", "*")
w.Header().Set("Access-Control-Max-Age", "3600")
w.Header().Set("Access-Control-Allow-Credentials", "true")
w.Header().Set("Access-Control-Allow-Headers", "Access-Control-Allow-Headers, Access-Control-Allow-Methods, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers")
w.Header().Set("Access-Control-Allow-Methods", "GET,HEAD,OPTIONS,POST,PUT,DELETE")

The service responds just fine on POSTMAN with no additional headers. Also, the setup is present on k8s and I am using ingress to expose the service securely.

Any help here wil be great. thanks!

I believe you will need the mode set to cors instead of no-cors.

Hi Josh thanks for the response.
I am now using XMLHttpRequest() will end to end cors enabled and that works fine. It even worked with an insecure connection unlike the ajax call.

Thanks!
