How can I implement it so that when a user enters the site, send him data via websocket?

Question

Python

Implementation for vk mini apps, the user id is passed to the url, I made sure that the data is saved in cookies, but it is possible to try to hack when changing cookies, the site is on flask, websockets is separate

Answer 1

Cookies cannot be used in vk mini apps because they can be lost. Use data from launch options https://vk.com/dev/vk_apps_docs3?f=6.%2B%D0%9F%D0%... or store data in vkshny storage https://vk.com/dev/vk_bridge_events_11 ?f=6.%2B%D0%...
