How to get Grails HeaderParam attributes

I came for ruby/rails background. I am facing issues to get header attributes of rest call.

In case of rails, I used to write below code to list all requested header attributes.

puts request.headers.inspect

Could any body please suggest me what is the equivalent for Grails ?

The request object is an instance of the Servlet API's HttpServletRequest interface, so you can use the getHeader and getHeaderNames methods

This is an example of how to print all the headers - add it where you can access the request object (e.g. inside a controller method):

request.getHeaderNames().each {        
    println(it + ":" + request.getHeader(it))
}

Also, remember in Groovy/Grails any getXXX method will treat XXX as a property. So, getHeader and getHeaderNames can be abbreviated to request.header 'someheadername' or request.headerNames

Take a look here. On this page you can find "The request object is an instance of the Servlet API's HttpServletRequest interface". You can use getHeader and getHeaderNames methods
