多个 WCF 服务可以共享一个公共 BaseAddress 吗? [英] Can several WCF services share a common BaseAddress?

问题描述

我有一个包含多个 WCF 服务的程序集，每个服务都有自己的契约.这一切都很好.服务的 app.config 中的服务配置如下所示:

I've got an assembly containing several WCF services, each with its own contract. It all works nicely. The service config in the app.config for the service looks like this:

<services>
  <service behaviorConfiguration="WcfService.AlyzaServiceBehavior"
    name="Sam.Alyza.WcfService.ServiceWebsites">
    <endpoint address="" binding="netTcpBinding" contract="Sam.Alyza.WcfInterface.IServiceWebsites">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8731/Design_Time_Addresses/SamAlyza/Websites/" />
      </baseAddresses>
    </host>
  </service>
  <service behaviorConfiguration="Sam.Alyza.WcfService.LogReaderServiceBehavior"
    name="Sam.Alyza.WcfService.ServiceLogReader">
    <endpoint address="" binding="netTcpBinding" contract="Sam.Alyza.WcfInterface.IServiceLogReader">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8731/Design_Time_Addresses/SamAlyza/LogReader/" />
      </baseAddresses>
    </host>
  </service>
  <service behaviorConfiguration="Sam.Alyza.WcfService.ServiceSystemverwaltungBehavior"
    name="Sam.Alyza.WcfService.ServiceSystemverwaltung">
    <endpoint address="" binding="netTcpBinding" contract="Sam.Alyza.WcfInterface.IServiceSystemverwaltung">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8731/Design_Time_Addresses/SamAlyza/Systemverwaltung/" />
      </baseAddresses>
    </host>
  </service>
  [...]
</services>

由于我有一个更大的项目，有更多的合同，我想有一种方法可以在不同的服务合同之间共享 BaseAddress.
如果这只是具有不同合同和端点的一项服务，我可以设置一个通用基地址，但如何为多个服务设置一个通用基地址?

Since I've got a bigger project in mind, with more contracts, I'd like to have a way to share the BaseAddress between the different service contracts.
If this would just be one service with different contracts and endpoints, I could set a ommon baseaddress, but how do I set a common baseaddress for more than one service?

当然，我需要为客户提供类似的东西.

Of course I'd need something similar for the client.

推荐答案

您可以将所有合约合并到一个类中，这样您就有一个服务，每个合约有一个基地址和一个(或多个)端点.

You can combine all contracts in one class, so you have one service with a baseaddress and one (or more) endpoint(s) per contract.

为了避免一个大的类文件，您可以使用部分关键字(假设您使用 c#)将类拆分到多个文件中.每个文件可以实现一个契约，这使得维护各个接口变得更加容易.

To avoid having one large class-file you can use the partial-keyword (asuming you use c#) to split the class across multiple files. Each file can implement one contract, that makes maintaining the individual interfaces much easier.

在 C++ 中，您可以使用 #includes 或多重继承，但这意味着大量的纪律......

In C++ you can use #includes or multiple inheritance, but that imply a large amount of discipline...

您的配置将如下所示:

<services>
  <service behaviorConfiguration="WcfService.AlyzaServiceBehavior"
    name="Sam.Alyza.WcfService.ServiceAll">
    <endpoint address="Websites/" binding="netTcpBinding" contract="Sam.Alyza.WcfInterface.IServiceWebsites">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="LogReader/" binding="netTcpBinding" contract="Sam.Alyza.WcfInterface.IServiceLogReader">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="Systemverwaltung/" binding="netTcpBinding" contract="Sam.Alyza.WcfInterface.IServiceSystemverwaltung">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8731/Design_Time_Addresses/SamAlyza/" />
      </baseAddresses>
    </host>
  </service>
</services>
