How to put a request in a redis queue

there are existing requirements. In order to avoid the problem of high concurrency, controller should put the request into the redis queue after obtaining the request.

I just got an overview of the queue of redis on the Internet, and found that I used the operation BLPOP or BRPOP, or Pub/Sub of list in Redis.

what I don"t understand here is what it is to put a request in a redis queue. Are you putting url in? You can understand the parameters.
