反模式
❌ Message Content for Commands
❌ 使用消息内容触发命令
Why bad: Message Content Intent is privileged and deprecated for bot commands.
Slash commands are the intended approach.
问题所在:消息内容意图是特权权限,且已被弃用作为机器人命令的触发方式。斜杠命令是官方推荐的方案。
❌ Syncing Commands on Every Start
❌ 每次启动时同步命令
Why bad: Command registration is rate limited. Global commands take up to 1 hour
to propagate. Syncing on every start wastes API calls and can hit limits.
问题所在:命令注册存在速率限制。全局命令最长需要1小时才能完成同步。每次启动都同步会浪费API调用次数,甚至触发限制。
❌ Blocking the Event Loop
❌ 阻塞事件循环
Why bad: Discord gateway requires regular heartbeats. Blocking operations
cause missed heartbeats and disconnections.
问题所在:Discord网关需要定期发送心跳包。阻塞操作会导致心跳包丢失,进而引发断开连接。
