nil { return nil, err } // 反序列化 return deserializeActivity(data) } func (r *RedisCache) SetActivity(id string, activity vocab.Type, ttl time.Duration) error { // 序列化并存储到Redis data, err : serializeActivity(activity) if err ! nil { return err } return r.client.Set(context.Background(), activity:id, data, ttl).Err() } // 批量处理优化 func processBatchActivities(activities []vocab.Type) error { // 批量处理活动减少数据库操作 batchSize : 100 for i : 0; i len(activities); i batchSize { end : i batchSize if end len(activities) { end len(activities) } batch : activities[i:end] // 批量处理逻辑 if err : processBatch(batch); err ! nil { return err } } return nil }3. 错误处理与监控// error_handling.go package main import ( github.com/go-fed/activity/pub github.com/prometheus/client_golang/prometheus github.com/prometheus/client_golang/prometheus/promauto ) // 监控指标 var ( activityPubRequests promauto.NewCounterVec(prometheus.CounterOpts{ Name: activitypub_requests_total, Help: ActivityPub请求总数, }, []string{method, endpoint, status}) activityProcessingTime promauto.NewHistogramVec(prometheus.HistogramOpts{ Name: activity_processing_seconds, Help: 活动处理时间, Buckets: prometheus.DefBuckets, }, []string{activity_type}) ) // 带监控的处理器 type MonitoredActor struct { pub.Actor } func (m *MonitoredActor) PostInbox(c context.Context, w http.ResponseWriter, r *http.Request) (handled bool, err error) { start : time.Now() defer func() { duration : time.Since(start).Seconds() activityProcessingTime.WithLabelValues(inbox).Observe(duration) }() handled, err m.Actor.PostInbox(c, w, r) status : success if err !
