Returns the response headers as key-->value string pairs following a RestServices call
The key-->value pairs are returned as a JavaScript object.
Accessing a key value where the name of the key has a hyphen in it needs to be accessed using headers["key-name"] syntax.
Example:
var response = services.rest.get("http://example.com/rest/users");
var headers = response.getHeaders();
var content = headers["Content-Type"];
if(content == 'application/json')
{
//do something with JSON
}
