的Android / iOS版客户端消耗WCF双工服务 [英] Android/iOS client consumes WCF Duplex service
问题描述
我想建立一个服务器/网络服务，它提供的API到Android / iOS版客户端。我使用WCF服务和客户端可以成功发送请求给服务器。现在，我打算让服务器能ping通客户端通知，有服务器和客户端的一些改变需要同步数据。
I am trying to build a server/web service which provides APIs to Android/iOS client. I am using WCF service and clients can send request to server successfully. 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.
现在的问题是：是否有可能使我的服务器到客户端平（的Android / iOS版），我就知道它有可能为Windows客户端通过使用wsDualHttpBinding但我不知道iOS和Android客户端。任何人都可以帮我说清楚？任何解决方案是AP preciated。
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. Anyone can help me to make it clear? Any solution is appreciated.
推荐答案
我不认为你可以做到这一点。为启动，而wsDualHttpBinding旨在是可互操作的，我不实际上beleive它是由比WCF任何otehr框架支撑。然后wsDualHttpBinding使用<一个href=\"http://msdn.microsoft.com/en-us/library/system.servicemodel.wsdualhttpbinding.clientbaseaddress.aspx\"相对=nofollow>客户端回调网址服务器需要联系。此网址无法将是一个手机上访问。你应该使用WebSockets，长轮询或设备操作系统的一些专有推送机制。
I don't think you can do it. For start, while wsDualHttpBinding is intended to be interoperable I don't beleive in practice it is supported by any otehr framework than WCF. Then wsDualHttpBinding uses a client callback url that the server needs to contact. This url is not going to be accessible on a phone. You should use websockets, long polling or some proprietary push mechanism of the device os.
