9. — Written in Go — Push requests to APNs and FCM — Simple HTTP APIs 9
10. Client FCM APNs Gorush POST /push JSON Body HTTPS APNs Protocol 10
11. — 系統需求 — ⾼高效能 (Good Performance) — ⾼高併發 (High Concurrency) — 簡單的 net/http 就可以達到⽬目標 — 學習⾨門檻低 11
12. — 異異步發送訊息 (Asynchronous push) — API Server 觸發條件 — 溫度過⾼高、⾎血壓過低 — API Server 需要快速回覆前端 — 後端架構不適合⾼高併發 (Nginx + PHP) 12
