my question is I am connecting with an api and this give me a file response.

this is the result file in my api

result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");

return result;

and i use this ajax to call the api

        $.ajax({
        type: 'GET',
        url: "http://localhost/api/Piezas/Imagen/" + @Model.PiezaId,
        contentType: "application/octet-stream",
        success: function (datos) {
            //$("#image").attr("src", "data:image/png;base64," + datos);
        }
    });
