示例

以下示例演示如何创建 MediaProtectionManager、设置 Properties 属性，以及为 ComponentLoadFailed 和 ServiceRequested 添加事件侦听器。 有关完整示例，请参阅 如何使用可插入 DRM 主题。 '''javascript

mediaProtectionManager = 新的 Windows.Media.Protection.MediaProtectionManager () ;

function ServiceRequested (e) { logMsg (“Got Enabler - system/type： {” + e.request.protectionSystem + “}/{” + e.request.type + “}”) ;e.completion.complete (true) ;}

function ComponentLoadFailed (e) { logMsg (e.information.items.size.toString () + “failed components”) ; logMsg (”

组件：

列出 (var i = 0 的故障组件;i.information.items.size < ; i++) { logMsg (”

“ + e.information.items[i].name + ”

Reasons=0x“ + e.information.items[i].reasons.toString (16) + ”

Renewal Id=“ + e.information.items[i].renewalId) ;}

e.completion.complete (false) ;}

function RebootNeeded (e) { logMsg (“Reboot Required”) ; }

mediaProtectionManager.addEventListener (“servicerequested”， ServiceRequested， false) ;mediaProtectionManager.addEventListener (“componentloadfailed”， ComponentLoadFailed， false) ;mediaProtectionManager.addEventListener (“rebootneeded”， RebootNeeded， false) ;

注解

此对象不直接实例化。 它由 MediaProtectionManager.ServiceRequested 事件创建，作为参数返回到 ServiceRequestedEventHandler 委托。
