閒聊Python應用在game server的開發
2 likes2,034 views
This document discusses using Python and Django for game server development. It describes using Python with Socket and Epoll for real-time features like player locations and chat. It then discusses using Django and REST APIs with polling for other functions. It provides examples of Puzzle & Dragon's game flow and API endpoints. It also notes some challenges like database access times, latency, and application server performance that can be addressed through techniques like reducing server-side computation, modifying designs, database sharding, caching, using NoSQL, and queues.

閒聊Python應用在game server的開發
- 2. Agenda ● Python應用在之前的專案中 ● Django與REST應用在遊戲開發上 ● 面臨的問題與挑戰
- 3. Before... ● Pure Python (Socket + Epoll) ● Django + PyAMF ● Django + REST
- 4. Socket vs Web Service ● Socket Server ○ Real Time ■ Player location info. ■ Chat ● Web Service ○ polling
- 5. REST API HTTP Method Data operate Description POST Create Create a resource without id. GET Read Get a resource. PUT Update Update a resource or create a resource with id if not existed. DELETE Delete Delete a resource
- 6. Framework ● Django ● Django REST framework
- 7. Why Django REST framework? Source of photo credit :http://django-rest-framework.org/
