How to send a POST request to a URL using Cisco TCL?

Question

Cisco

You need to send the IP address to pdd.yandex.ru to change the value of the DNS record. PDD only accepts POST requests.
ip ddns update method http - sends a GET. Therefore, I began to look towards sending a request by a script, but I can’t find it, tell me.
