设置通知侦听器

本主题介绍如何为云眼灰度实验 Swift SDK 设置和删除通知侦听器。

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

有关代码示例,请参阅以下部分。

添加和删除所有通知侦听器

下面的示例代码演示如何添加侦听器、删除侦听器、删除特定类型的所有侦听器(例如所有决策侦听器)以及删除所有侦听器。

Swift目标-C

// Add a notification listener let notificationId = eyeofcloud.notificationCenter.addDecisionNotificationListener(decisionListener: { (type, userId, attributes, decisionInfo) in // Send data to analytics provider here }) // Remove a specific listener eyeofcloud.notificationCenter.removeNotificationListener(notificationId: notificationId!) // Remove all Notification Listeners eyeofcloud.notificationCenter.clearAllNotificationListeners() // Remove all Notification Listeners of a certain type eyeofcloud.notificationCenter.clearNotificationListeners(type: .decision)

// Add a notification listener NSNumber *notificationId = [self.eyeofcloud.notificationCenter addDecisionNotificationListenerWithDecisionListener:^(NSString *type, NSString *userId, NSDictionary<NSString *,id> *attributes, NSDictionary<NSString *,id> *decisionInfo) { // Send data to analytics provider here }]; // Remove a specific listener [eyeofcloud.notificationCenter removeNotificationListenerWithNotificationId:notificationId]; // Remove all Notification Listeners [eyeofcloud.notificationCenter clearAllNotificationListeners]; // Remove all Notification Listeners of a certain type [eyeofcloud.notificationCenter clearNotificationListenersWithType:NotificationTypeDecision];

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每种类型的通知侦听器。

Swift目标-C

// SET UP DECISION NOTIFICATION LISTENER let onDecision : DecisionListener = {[weak self](decisionType, userId, attributes, decisionInfo) in // Add a DECISION Notification Listener for type FLAG if decisionType == "flag" { // Access information about feature, for example, key and enabled status print(decisionInfo["flagKey"]) print(decisionInfo["enabled"]) print(decisionInfo["decisionEventDispatched"]) } } self.eyeofcloudClient?.notificationCenter?.addDecisionNotificationListener(decisionListener: onDecision) // SET UP LOG EVENT NOTIFICATION LISTENER let onLogEvent : LogEventListener = {[weak self] (url, logEvent) in // process the logEvent object here (send to analytics provider, audit/inspect data) } self.eyeofcloudClient?.notificationCenter?.addLogEventNotificationListener(logEventListener: onLogEvent) // SET UP DATAFILE CHANGE NOTIFICATION LISTENER let onDatafileUpdate : DatafileChangeListener = {[weak self] (datafile) in } self.eyeofcloudClient?.notificationCenter?.addDatafileChangeNotificationListener(datafileListener: onDatafileUpdate) // SET UP TRACK LISTENER let onTrack : TrackListener = { [weak self](eventKey, userId, attributes, eventTags, event) in // process the event here (send to analytics provider, audit/inspect data) } self.eyeofcloudClient?.notificationCenter?.addTrackNotificationListener(trackListener: onTrack)

// SET UP ACTIVATE NOTIFICATION LISTENER (void)[self.eyeofcloudClient.notificationCenter addActivateNotificationListenerWithActivateListener:^(NSDictionary<NSString *,id> * _Nonnull experiment, NSString * _Nonnull userId, NSDictionary<NSString *,id> * _Nullable attributes, NSDictionary<NSString *,id> * _Nonnull variation, NSDictionary<NSString *,id> * _Nonnull event) { }]; // SET UP DECISION NOTIFICATION LISTENER (void)[self.eyeofcloudClient.notificationCenter addDecisionNotificationListenerWithDecisionListener: ^(NSString * _Nonnull decisionType, NSString * _Nonnull userId, NSDictionary<NSString *,id> * _Nullable attributes, NSDictionary<NSString *,id> * _Nonnull decisionInfo) { // Add a DECISION Notification Listener for type FEATURE if ([decisionType isEqualToString:@"feature"]) { // Access information about feature, for example, key and enabled status NSLog(decisionInfo[@"featureKey"]); NSLog(decisionInfo[@"featureEnabled"]); NSLog(decisionInfo[@"source"]); } }]; // SET UP LOG EVENT NOTIFICATION LISTENER (void)[self.eyeofcloudClient.notificationCenter addLogEventNotificationListenerWithLogEventListener:^(NSString * _Nonnull url, NSDictionary<NSString *,id> * _Nonnull logEvent) { // process the logEvent object here (send to analytics provider, audit/inspect data) }]; // SET UP DATAFILE CHANGE NOTIFICATION LISTENER (void)[self.eyeofcloudClient.notificationCenter addDatafileChangeNotificationListenerWithDatafileListener:^(NSData * _Nonnull datafile) { }]; // SET UP TRACK LISTENER (void)[self.eyeofcloudClient.notificationCenter addTrackNotificationListenerWithTrackListener:^(NSString * _Nonnull eventKey, NSString * _Nonnull userId, NSDictionary<NSString *,id> * _Nullable attributes, NSDictionary<NSString *,id> * _Nullable eventTags, NSDictionary<NSString *,id> * _Nonnull event) { // process the event here (send to analytics provider, audit/inspect data) }];
