Utilize X-Forwarded Headers

[aaron-hooper]

Please support the X-Forwarded headers (x-forwarded-host, x-forwarded-prefix, x-forwarded-port, x-forwarded-proto) when they exist to allow the swagger docs to be properly served from behind a reverse proxy.

Hi @aaron-hooper,

The procy headers are natively supported by spring-boot.
Please have a look at the answer of #153. This should work without any issue.

Please don't forget to give a feedback about which option resolved your issue.

Setting server.forward-headers-strategy=framework does allow the redirect to resolve, but there is still an issue with the static content.

When accessing the app directly without going through a proxy localhost:8080/swagger-ui.html the static resources are resolved, ie localhost:8080/swagger-ui/swagger-ui-bundle.js.

However when accessing via the reverse proxy localhost:8081/app-context/swagger-ui.html the static resources are returning a 404 because the path is missing /swagger-ui/ ie localhost:8081/app-context/swagger-ui-bundle.js.

Hi,

You need to make sure you reverse proxy is also well configured:
For example using apache 2:

RequestHeader set X-Forwarded-Prefix "/custom-path"

Did you try with the Bean configuration?

@Bean
ForwardedHeaderFilter forwardedHeaderFilter() {
   return new ForwardedHeaderFilter();
}

Is the /custom-path a fixed one?
