how to set custom headers with a $resource action?

Question

with $http, we can do this:

var config = { headers: { \'something\': \'anything\' } };          
$http.get(\'url/to/json\', config)
    .success(function()

The headers object inside a resource action supports both static values for its fields, but also dynamic values returned from a function.

$resource('url/to/json', {}, {
        get: {
            method: 'GET',
            headers: { 
               'header_static': 'static_value',
               'header_dynamic': dynamicHeaderVal
            }
        }
});

function dynamicHeaderVal(requestConfig){
     // this function will be called every time the "get" action gets called
     // the result will be used as value for the header item
     // if it doesn't return a value, the key will not be present in the header
}
