问题描述
我正在努力的目标是拥有一个WCF路由服务，该服务可以接收来自客户端的消息，将它们持久保存到某种类型的数据存储中，然后将其处理/发送到其目标WCF服务。
The goal I'm working toward is having a WCF routing service that can receive messages from clients, persist them to some type of data store, and then process/send them to their destination WCF services.
注意事项：
- 您可以使用（概述和）
- ClientViaBehavior无法与basicHttpBinding一起使用，因此我需要使用wsHttpBinding（basicHttpBinding不会在消息，很难找到）
- WCF消息对象本身被发送到路由服务，在该处可以将它作为序列化的字符串保存下来
- 我不要路由服务以了解消息中的内容-因此，该服务将不会引用所涉及的数据合同
- 当需要将消息路由到其目的地时，我需要能够在路由服务和目标服务之间创建通道
- 路由服务并不了解每个目标服务是理想的-理想情况下，WCF可以基于动态创建适当的通道关于正在处理的消息的内容/标题。
- You can create a routing service by using the ClientViaBehavior (outlined here and here)
- The ClientViaBehavior will not work with basicHttpBinding, so I need to use wsHttpBinding (basicHttpBinding doesn't set the "To" header on the message, found out the hard way)
- The WCF Message object itself is sent to the Routing Service, where it can be persisted as a serialized string
- I don't want the Routing Service to know what's in the message - consequently, the service will not have a reference to the Data Contracts involved
- When the time comes to route the Message to its destination, I need to be able to create a channel between the Routing Service and the Destination Service
- It is not desirable for the Routing Service to be aware of each destination service - ideally, WCF could create the proper channel dynamically based on the content/headers of the message being processed.
WCF要求太多了吗？ （我觉得这可能是...）
Is this too much to ask of WCF? (I have a feeling it might be...)
任何有关如何实现这种目标的建议都会受到赞赏。
Any advice on how to accomplish something like this would be appreciated.
推荐答案
如果您使用的是.NET 4（或可以移动到它），则WCF 4.0引入了自己的RoutingService基础结构。
If you're on .NET 4 (or can move to it), WCF 4.0 has introduced a RoutingService infrastructure of its own.
在重新发明轮子之前先检查一下！
