Receive parameter in delete request

Question

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

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

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

But on the island of Nodejs this .log() prints only {}.

I also tried this way (found 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 ignored 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
    };
});

In the controller I call the service, this way:

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

the delete service of the $http method, returns you a promisse ie, to access server return data, must be implemented as follows.

the delete service does not accept an OBJECT to be sent, because the same at the end performs a Get to the server, ie the information must go in the URL, so you can only pass parameters, and not a complete object.

 $http.delete("http://localhost:3412/contatos/" + contato.ID).success(function (data, status) {
                console.log(data); // Retorno seu Data
            });
