设置通知侦听器

本主题介绍如何设置和删除云眼特性标帜(Feature Flag)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特性标帜(Feature Flag)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。

有关代码示例，请参阅以下部分。

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)
