设置通知侦听器

本主题介绍如何设置和删除云眼灰度发布（特性标帜）AB实验 Go SDK 的通知侦听器。

通知侦听器触发您在 SDK 中触发某些操作时定义的回调函数。

最常见的用例是将所有灰度发布（特性标帜）决策的流发送到分析提供商或内部数据仓库，以将其与您拥有的有关用户的其他数据联接。

通知侦听器类型

有关通知侦听器类型和用例的更多信息，请参阅通知侦听器。

设置每种类型的通知侦听器

下面的示例代码演示如何设置和删除每种类型的通知侦听器。

Go

// Create default Client eyeofcloudFactory := &client.EyeofcloudFactory{ SDKKey: "[SDK_KEY_HERE]", } eyeofcloudClient, _ := eyeofcloudFactory.Client() // SET UP DECISION NOTIFICATION LISTENER onDecision := func(notification notification.DecisionNotification) { // Add a DECISION Notification Listener for type FLAG if string(notification.Type) == "flag" { // Access information about feature, for example, key and enabled status fmt.Print(notification.DecisionInfo["flagKey"]) fmt.Print(notification.DecisionInfo["enabled"]) fmt.Print(notification.DecisionInfo["decisionEventDispatched"]) } } notificationID, _ := eyeofcloudClient.DecisionService.OnDecision(onDecision) // REMOVE DECISION NOTIFICATION LISTENER eyeofcloudClient.DecisionService.RemoveOnDecision(notificationID) // SET UP LOG EVENT NOTIFICATION LISTENER onLogEvent := func(eventNotification event.LogEvent) { // process the logEvent object here (send to analytics provider, audit/inspect data) } notificationID, _ = eyeofcloudClient.EventProcessor.OnEventDispatch(onLogEvent) // REMOVE LOG EVENT NOTIFICATION LISTENER eyeofcloudClient.EventProcessor.RemoveOnEventDispatch(notificationID) // SET UP EYEOFCLOUD CONFIG NOTIFICATION LISTENER // listen to EYEOFCLOUD_CONFIG_UPDATE to get updated data onConfigUpdate := func(notification notification.ProjectConfigUpdateNotification) { } notificationID, _ = eyeofcloudClient.ConfigManager.OnProjectConfigUpdate(onConfigUpdate) // REMOVE EYEOFCLOUD CONFIG NOTIFICATION LISTENER eyeofcloudClient.ConfigManager.RemoveOnProjectConfigUpdate(notificationID) // SET UP TRACK LISTENER onTrack := func(eventKey string, userContext entities.UserContext, eventTags map[string]interface{}, conversionEvent event.ConversionEvent) { // process the event here (send to analytics provider, audit/inspect data) } notificationID, _ = eyeofcloudClient.OnTrack(onTrack) // REMOVE TRACK LISTENER eyeofcloudClient.RemoveOnTrack(notificationID)
