Kolleksiya qiladigan websayt bor.
User kolleksiyaga item qo'shgan vaqtida Itemda 3 ta id, name, tag majburiy fieldlari bo'ladi va qo'shimcha fieldlarini o'zi xohlagan(maksimal 3-4 ta qo'shimcha) ravishda tanlash imkoniga ega.
Masalan, Kitob id, name, tag fieldlari aniq bo'ladi va qo'shimcha author, description, publishdate fieldlari user xohlagani uchun qo'shiladi.
qanaqa qilib buni realizatsiya qilish mumkin?

Live stream lar UDP protokolida ishlaydi. Bunga misol socket. Server hosil qilasiz, live stream qilayotgan foydalanuvchi o'zidagi videoni serverga uzatadi, server kelgan ma'lumotni boshqa userlarga uzatadi, shu bilan live stream hosil qilinadi(umumiy tushuncha shunday)

Videoni yozib olish masalasi serverda bo'ladi.

WebSocketni ishlatsangiz bo'ladi. bunga client mobile yoki frontend qismida yoziladi

Ассалом алейкум хаммага. Project да jwt қўлланилган. http да security with jwt ишлаб турибди хатосиз.. Проектни серверга деплой қилгандан кейин JWT INVALID SIGNATURE бервотти. Деплой қилингандан кейин хам http ишлавотти. Муаммо нимада эканлигига бош қотган.
