Not sure I understand the question, but what would be wrong with simply looking at the name of the interest/data?

<div style="margin:0;" class="">    I use ndn-consumer-zipf-mandelbrot.cpp and set the number of content to 3. My understanding is that every interest package sent by the consumer belongs to one of the three contents, such as A, B or C. So, when a consumer
 sends an interest package, how can I know that the interest package belongs to A, B or C? Similarly, the returned data packet should also be divided into three, how do I know which one the data packet belongs to?</div>
