Get url params in action compositions

Question

I have an Interceptor (Action composition) defined for my controllers. I need to access url parameters in request

i.e. to enter conf below, how do I access the Id parameter inside my Action composition?

GET /jobs/:id controllers.JobManager.getlist(id: Int)

my action method hook class only refers to my Http.Context object. while accessing the body of the request is obvious that the URL is not.

Take it out yourself. In your example, the path is 6 characters long plus the id length.

String path = ctx.request().path();
String id = path.substring(6, path.length());

This decision depends on the length of the route. In addition, you can pass the start and end parameters to your action:

@With({ ArgsAction.class })
@Target({ ElementType.TYPE, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
public @interface Args {

    int start() default -1;
    int end() default -1;

}

action :

public class ArgsAction extends Action<Args> {

    @Override
    public Promise<Result> call(Context ctx) throws Throwable {
        final int start = configuration.start();
        final int end = configuration.end();
        if (start != -1) {
            final String path = ctx.request().path();
            String arg = null;
            if (end != -1) {
                arg = path.substring(start, end);
            } else {
                arg = path.substring(start, path.length());
            }
            // Do something with arg...
        }
        return delegate.call(ctx);
    }
}

JobManager:

@Args(start = 6)
public getlist(Integer id) {
    return ok();
}
