Windows推播通知服务（常见别称为Windows通知服务或WNS）是一项由微软开发、适用于Microsoft Windows以及Microsoft Windows Mobile等平台的服务。其主要功能在于让软体开发人员可将推播资料（包含Toast通知或动态砖的更新）传送至支援此服务的Windows或Windows Mobile应用程式中。[1]该服务取代了原有的Microsoft推播通知服务，发行时支援的作业系统仅有Windows 8，不久后才增加Windows Phone 8.1。[2]
技术细节
编辑设计及相容性
编辑Windows推播通知服务（WNS）的设计意在取代原有的Microsoft推播通知服务（MPNS），其中后者仅在Windows Phone 8中有原生支援。软体开发人员仍可在安装于较新版本之Windows Mobile（Windows Phone 8或Windows Phone 8.1）上的应用程式使用旧有的MPNS，前提是该软体已注册MPNS且需转换为适用于新版作业系统的Microsoft Silverlight应用程式。[3]
2015年，微软宣布将扩展WNS的应用至通用Windows平台架构，让推播资料可直接传送至Windows 10、Windows 10 Mobile以及XBOX等作业系统、或是利用通用API呼叫程序及POST请求传送至WNS支援的其它平台。[4]
在Build 2015的发表会中，微软公布了一款通用Windows平台的桥接器，让开发人员可将现有软体的程式码从Android或iOS转换至Windows 10 Mobile并于Windows Store中发行。[5]2015年8月，有报导指出微软的Android桥接器工具集及其相关文件已被泄漏至网际网路且可供下载[6]；遭泄漏版本的工具集要求开发人员注册并使用WNS以将通知资料传送至应用程式中，且不允许Google云端通讯的使用。后来，微软终止了Android桥接器的相关计画，并将资源继续集中于iOS桥接器的支援。[7]
在Build 2016的发表会中,微软宣布了WNS以及Windows 10作业系统的一项更新：运行Android和iOS的装置可将已收到的推播通知转送至Windows 10中，并供使用者检视或删除。[8]
Architecture
编辑The architecture of the Windows Push Notification Service is similar to that of its predecessor, in that it consists of servers and interfaces that generate, maintain, store, and authenticate unique identifiers (called Channel URI Identifiers) for all devices that register to use the service.[2] When a device enrolls to receive data and notification information using the WNS, it first sends a device registration request to WNS network. The WNS network acknowledges the request, and responds with the device's unique Channel URI Identifier.[9] Typically, the device will then send its identifier to a server owned by the developer so that it can be stored and used for sending notifications.[1] When the app developer wishes to transmit a notification or other WNS data to the device, it will transmit a POST request to the WNS network.[10] The network will acknowledge and authenticate the request. If the authentication succeeds, the data to be transmitted is enqueued and then sent to the device from the WNS network using the Channel URI Identifier.
