make interdomain network request to Confluence

[Mark Sinakaev]

How to organize an interdomain network request in order to get an avatar?
My code:

Error:

I have an application which has:

1) Back => Spring Boot
2) Front => ReactJs
The back requests data from the Jira some data and displays it. Works through JiraRestClient, then it passes to front via Rest Api. Working fine.

Is it possible to somehow make requests to https://wiki/rest/api/user?username=Sinakaev from the front without CORS error?
I can not find more detailed documentation on Confluence.
Confluence is an Atlassian project, we have it deployed on-premise, maybe some configs can be changed through engineers.

Hi @Mark Sinakaev 
Welcome to the Atlassian Community.

You might be able to circumvent it by working with your Confluence administrators to disable the clickjacking protection, although this might not be safe.

There might be better options to allow it for targeted systems if you can rewrite headers through proxy or load balancer.

There's an example on this Jira feature request: https://jira.atlassian.com/browse/JRASERVER-67896.

Kind regards,
