Openapi Server Object url supports reverse proxy

[oursy]

There is a webflux-functional endpoint A service. Proxy via Spring Cloud Gateway.
A service is behind the gateway, so use the following solution
https://springdoc.org/faq.html#how-can-i-deploy-springdoc-openapi-ui-behind-a-reverse-proxy

After setting the forward-headers-strategy: framework property
The webflux-functional endpoint request starts at 404.
Specific information can be viewed spring-projects/spring-framework#25270

@oursy,

The settings are for reverse proxies: apache/nginx or others ...
For spring-cloud-gateway, you don't need to set server.forward-headers-strategy=framework.

Basically, all what you need:

• Declare springdoc-openapi-webflux-ui, on the spring-cloud-gateway side
• Declare springdoc-openapi-webflux-core, on your back-end services that using spring-webflux (account-service).

You can have access,
1)- By just updating, your application.yml on the gateway side:

springdoc:
  swagger-ui:
    urls[0]:
      name: account
      url: /account/v3/api-docs/

2)- Or programatically: This is the sample demo code for the integration with spring-cloud-gateway:

You can find attached, the working sample as well;
