How to add a custom header for every request in Swagger-UI version 3.0

问题

I want to support multiple json versions on my swagger-ui version 3.0. The second json at every ajax call I want to add a custom header with name x-api-version and value 2

I tried this one:

$.ajaxSetup({
    beforeSend: function(xhr) {
        xhr.setRequestHeader('x-my-custom-header', 'some value');
    }
});

But it is not working. The documentation of swagger ui 3.0.0 is poor and I can't find a solution
