POST not getting data but $.ajax does.

Maybe this is the problem with my understanding of Vue resource, but why does this work:

_this = this;

            $.ajax({
                type: 'POST',
                url: requestURL,
                async: false,
                success: function (data) {
                    _this.$set('cartData', data);
                }
            });

But this does not:

this.$http.post(requestURL).then(function(response){
        this.$set('cartData', data);
})

I get a “Headers already sent error”. Backend for this example is Symfony 2.

@evertramos I think I did, but it was a long time ago. the project is finished, so I can’t check it now. But thanks for the suggestion.

Have you tried a simple:

this.cartData = data;
