ratpack public address of your server

ratpackGetPublicAddress.md

Ratpack handlers have access to ratpack internal components. Especially:

• context - implements interface ratpack.handling.Context
• registry - implements interface ratpack.registry.Registry
• publicAddress - implements interface ratpack.server.PublicAddress

context and registry variables are accessible without declaration. The other has to be declared as handler parameter.

In order to get public address of ratpack application declare publicAddress variable in your handler. In ratpack.groovy file import:

import ratpack.server.PublicAddress

and then have an access to PublicAddress instance. getAddress method requires ratpack context as parameter.

ratpack {
    get("/api") { PublicAddress publicAddress ->
        log.debug("Server address: ${publicAddress.getAddress(context)}")
    }
}
