消息传送要点

本页记录了有关使用消息传送组件在网站上包含消息传送功能的详细信息。

客户端的要点

撰写消息

消息列表 （用于收件箱、已发送和垃圾桶）

另请参阅客户端自定义

服务器端的要点

• 配置消息传送

• 用于SCF组件 的消息传送客户端API

• 服务 的消息传送API

• 消息端点

• 服务器端自定义

valid: mb.setInboxPath( "/mail/inbox" );
 not valid: mb.setInboxPath( "/mail/inbox/" );

社区站点

使用向导创建的社区站点结构将在选择时包含消息传送功能。 请参阅社区站点控制台的User Management设置。

示例代码：消息收到通知

社交消息功能引发操作事件，例如send、marking read、marking delete。 可以捕获这些事件并对事件中包含的数据执行相应操作。

以下示例是一个事件处理程序，它监听message sent事件，并使用Day CQ Mail Service向所有消息收件人发送电子邮件。

要尝试服务器端示例脚本，您需要开发环境并能够构建OSGi包。

1. 以管理员身份登录 [CRXDE|Lite](http://localhost:4502/crx/de)

2. 在/apps/engage/install中创建具有任意名称的bundle node，例如

   • 符号名称:com.engage.media.social.messaging.messagingNotification
   • 名称:入门教程消息通知
   • 描述:向用户发送电子邮件通知的示例服务
   • 包: com.engage.media.social.messaging.notification

3. 导航至 /apps/engage/install/com.engage.media.social.messaging.MessagingNotification/src/main/java/com/engage/media/social/messaging/notification

   1. 删除自动创建的Activator.java类
   2. 创建类MessageEventHandler.java
   3. 将以下代码复制/粘贴到MessageEventHandler.java中

4. 单击​Save All

5. 导航到/apps/engage/install/com.engage.media.social.messaging.MessagingNotification/com.engage.media.social.messaging.MessagingNotification.bnd并按照MessageEventHandler.java代码中的说明添加所有import语句。

6. 构建包

7. 确保配置了Day CQ Mail ServiceOSGi服务

8. 以演示用户身份登录，并向其他用户发送电子邮件

9. 收件人应收到一封关于新消息的电子邮件
