如何在代码而不是配置中创建WCF EndPointBehaviors？

Question

我有以下Xml配置

<system.serviceModel>
    <services>
         <service name="MyService.MyServiceREST" behaviorConfiguration="MyServiceTypeBehaviors">
            <host>
                <baseAddresses>
                    <add baseAddress="http://localhost:1234/MyService/xml"/>
                </baseAddresses>
            </host>
            <endpoint address="" binding="webHttpBinding" behaviorConfiguration="xmlBehavior" contract="MyService.IMyService" />
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyServiceTypeBehaviors" >
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="True"/>
            </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
            <behavior name="xmlBehavior">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
</system.serviceModel>

我想用C#代码实现而不是使用配置.

我无法弄清楚使用webHttp将EndPoint作为REST服务公开的人.

ServiceHost serviceHost = new ServiceHost(singletonInstance, "http://localhost:1234/MyService/xml");

// Create Meta Behavior
ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
behavior.HttpGetEnabled = true;

serviceHost.Description.Behaviors.Add(behavior);

Binding mexBinding = MetadataExchangeBindings.CreateMexHttpBinding();

serviceHost.AddServiceEndpoint(typeof(IMetadataExchange), mexBinding, "mex");

WSHttpBinding httpBinding = new WSHttpBinding(SecurityMode.None);

serviceHost.AddServiceEndpoint(typeof(MyService.IMyService), httpBinding, "rest");

通常,在使用WCF执行REST时,您可以使用<webHttp>config中的行为,也可以使用WebServiceHost该类(而不是"普通的vanilla" ServiceHost).使用WebServiceHost包含所有必要的调整和点点滴滴来使REST工作 - 不再需要webHttp行为.

当然,这意味着,您需要一个单独的WebServiceHost(in System.ServiceModel.Web),它将服务作为REST专门托管.这可能是也可能不是你想要的:

WebServiceHost webServiceHost = 
    new WebServiceHost(singletonInstance, "http://localhost:1234/MyService/xml");

WebHttpBinding webBinding = new WebHttpBinding();
webServiceHost.AddServiceEndpoint(typeof(MyService.IMyService), webBinding, "rest");

您拥有的另一个选项是将服务端点添加到常规服务主机,并在该端点上配置Web http行为 - 端点(和服务)行为只是常规.NET类,毕竟,您可以实例化,以及添加到适当的Behaviors集合(在服务或个别端点上):

WebHttpBinding restBinding = new WebHttpBinding();

ServiceEndpoint restSEP = 
    serviceHost.AddServiceEndpoint(typeof(MyService.IMyService), 
                                   restBinding, "rest");
restSEP.Behaviors.Add(new WebHttpBehavior());

我希望这两种方式都能带给你你的目标!(或者至少让你离得更近:-)
