Receive parameter in delete request

I am trying to pass a parameter to my DELETE request, I tried to do the following:

Use the same way I use in GET (where it works normal).

app.delete('/contatos', function(req, res){
    var obj = req.body;
    console.log(obj);
});

However in the NodeJS console this .log() prints only {} .

I've also tried this way (I found it in SOen ):

app.delete('/contatos',function(req, res){
    var obj = req.body.data;
    console.log(obj);
});

But the same thing happened. Maybe the DELETE implementation is different from GET and POST and I skipped some step.

I am requesting the API from AngularJS, with the following service:

angular.module("lista").factory("contatosAPI", function($http){     
    var _saveContato = function(contato){
        return $http.post("http://localhost:3412/contatos", contato);
    };

    var _deleteContato = function(contato){
        console.log(contato); //Aqui o objeto está normal
        return $http.delete("http://localhost:3412/contatos", contato);
    };

    return {
        saveContato: _saveContato,
        deleteContato: _deleteContato
    };
});

controller I call the service, like this:

$scope.apagarContatos = function(contato){      
    contatosAPI.deleteContato(contato);
};
