OAuth2 redirect broken in WebFlux when context-path is not set to root

[neuroretransmit]

Describe the bug
When spring.webflux.base-path is set to a different context, the oauth2-redirect.html is broken. It tries to send you to root.

For instance, after authenticating at /v1/webjars, the redirect sends you to /webjars. You can change the path and it closes the redirect.

To Reproduce
Steps to reproduce the behavior:

• What version of spring-boot you are using?
  • 2.5.6
• What modules and versions of springdoc-openapi are you using?
  • security
  • webflux
• What is the actual and the expected result using OpenAPI Description (yml or json)?
• Provide with a sample code (HelloController) or Test that reproduces the problem

Expected behavior
Redirected to /context-root/webjars/...

@optimisticninja,

• Which springdoc-openapi version are you using ?
• Are you able to provide any Minimal, Reproducible Example - with HelloController that reproduces the problem?

Hi @bnasslahsen producing a minimal example may be difficult given that oauth2 would need an authorization server. You may view the project here

As for the versions:

dependencyManagement {
    dependency group: 'io.springfox', name: 'springfox-swagger-common', version: '3.0.0'
    dependencySet(group: 'org.springdoc', version: '1.5.2') {
      entry 'springdoc-openapi-webflux-ui'
      entry 'springdoc-openapi-security'
    }
  }
}

It doesn't look like there is a workaround, the redirect path property springdoc.swagger-ui.oauth2RedirectUrl starts after /webjars at /swagger-ui/

| /swagger-ui/oauth2-redirect.html | String. OAuth redirect URL.

Upon further inspection, this functionality needs to be ported to the webflux-ui project.

@optimisticninja,

First, make sure you are using the last stable version v1.5.12, before reporting any issues.
There is no known issues with the OAuth2 redirect url.

I have updated the demos, that shows it is just working fine with spring.webflux.base-path.

• https://github.com/springdoc/springdoc-openapi-demos/tree/master/springdoc-openapi-oauth2

If you are still facing the issue, then i invite to provide a sample test like this one, which explains what you are facing.

This ticket will be now closed and can reopened if any relevant information is provided.

Thank you and sorry for wasting your time. 1.5.12 fixed the issue.
