[英]Android/iOS client consumes WCF Duplex service

原文 2013-07-12 03:56:27 1 1 android/ ios/ wcf/ web-services/ duplex

I am trying to build a server/web service which provides APIs to Android/iOS client. 我正在尝试构建一个服务器/ Web服务，该服务向Android / iOS客户端提供API。 I am using WCF service and clients can send request to server successfully. 我正在使用WCF服务，客户端可以将请求成功发送到服务器。 Now, I am going to make server enable to ping client to notify that there some changes in server and client need to synchronize data. 现在，我将使服务器能够对客户端进行ping操作，以通知服务器和客户端中有一些更改需要同步数据。

The question is: Is it possible to enable my server to ping client (Android/iOS), I knew that it is possible for Windows client by using wsDualHttpBinding but I am not sure about iOS and Android client. 问题是：是否可以使我的服务器对客户端（Android / iOS）进行ping操作，我知道可以使用wsDualHttpBinding对Windows客户端执行ping操作，但我不确定iOS和Android客户端。 Anyone can help me to make it clear? 有人可以帮我弄清楚吗？ Any solution is appreciated. 任何解决方案表示赞赏。

I don't think you can do it. 我认为您无法做到。 For start, while wsDualHttpBinding is intended to be interoperable I don't beleive in practice it is supported by any otehr framework than WCF. 首先，尽管wsDualHttpBinding旨在实现互操作，但实际上我并不相信它会得到WCF之外的任何其他框架的支持。 Then wsDualHttpBinding uses a client callback url that the server needs to contact. 然后，wsDualHttpBinding使用服务器需要联系的客户端回调URL 。 This url is not going to be accessible on a phone. 无法在手机上访问该URL。 You should use websockets, long polling or some proprietary push mechanism of the device os. 您应该使用网络套接字，长时间轮询或设备操作系统的某些专有推送机制。
