Question

我无法弄清楚在我实施＆＃34; v2＆＃34;之后出现的WCF服务问题？与它签订合同以扩展功能。一切都很好，但当我尝试在浏览器中访问该服务时，我只是被告知它无法连接。当我尝试将其添加为服务引用时，我会收到有关连接问题的类似消息。但是，当我从配置文件中删除扩展合同的端点时，保留前一个＆＃34; v1＆＃34;版本完好无损，工作正常。

这是＆＃34; v1＆＃34;合同：

namespace Company.Services.Ticketing.Retail.Contracts
{
    [ServiceContract(Name = "OutletReportingContract_v1", Namespace = "https://enterprise.company.ie/Services/Retail")]
    public interface IOutletReportingContract_v1
    {
        /* methods */
    }
}

这是＆＃34; v2＆＃34;合同：

namespace Company.Services.Ticketing.Retail.Contracts
{
    [ServiceContract(Name = "OutletReportingContract_v2", Namespace = "https://enterprise.company.ie/Services/Retail")]
    public interface IOutletReportingContract_v2 : IOutletReportingContract_v1
    {
        /* methods */
    }
}

以下是Web.config中的端点：

  <service name="Company.Services.Ticketing.Retail.OutletService" behaviorConfiguration="Public">
    <endpoint address="1" binding="wsHttpBinding" bindingConfiguration="Standard" name="OutletReportingContract_v1" 
        contract="Company.Services.Ticketing.Retail.Contracts.IOutletReportingContract_v1" />
    <endpoint address="2" binding="wsHttpBinding" bindingConfiguration="Standard" name="OutletReportingContract_v2" 
        contract="Company.Services.Ticketing.Retail.Contracts.IOutletReportingContract_v2" />
    <endpoint address="mex" binding="mexHttpsBinding" name="IMetadataExchange" contract="IMetadataExchange" />
  </service>

以下是事件查看器中显示的错误消息：

WebHost无法处理请求。发件人信息：System.ServiceModel.Activation.HostedHttpRequestAsyncResult / 28075619 例外：System.Web.HttpException（0x80004005）：没有频道主动收听＆＃39; https://phil-pc.company.local/Services/Retail/OutletService.svc/_vti_bin/ListData.svc/ $元数据＆＃39;。这通常是由错误的地址URI引起的。确保将消息发送到的地址与服务正在侦听的地址匹配。 ---＆GT; System.ServiceModel.EndpointNotFoundException：没有频道主动收听＆＃39; https://phil-pc.company.local/Services/Retail/OutletService.svc/_vti_bin/ListData.svc/ $元数据＆＃39;。这通常是由错误的地址URI引起的。确保将消息发送到的地址与服务正在侦听的地址匹配。在System.ServiceModel.Activation.HostedHttpTransportManager.HttpContextReceived（HostedHttpRequestAsyncResult结果）在System.ServiceModel.Activation.HostedHttpRequestAsyncResult.HandleRequest（）在System.ServiceModel.Activation.HostedHttpRequestAsyncResult.BeginRequest（）在System.Runtime.AsyncResult.End [TAsyncResult]（IAsyncResult结果）在System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End（IAsyncResult结果）进程名称：w3wp 进程ID：8148

现在有点难过，并希望得到任何帮助：）

您需要在web.config中分隔您的服务声明。

假设您的实现类名为OutletService_v1＆amp; OutletService_v2你应该得到类似的东西：

＆＃13;

<services>
  <service name="Company.Services.Ticketing.Retail.OutletService_v1" behaviorConfiguration="Public">
    <endpoint binding="wsHttpBinding" bindingConfiguration="Standard" contract="Company.Services.Ticketing.Retail.Contracts.IOutletReportingContract_v1" />
    <endpoint address="mex" binding="mexHttpsBinding" name="IMetadataExchange" contract="IMetadataExchange" />
  </service>

  <service name="Company.Services.Ticketing.Retail.OutletService_v2" behaviorConfiguration="Public">
    <endpoint binding="wsHttpBinding" bindingConfiguration="Standard" contract="Company.Services.Ticketing.Retail.Contracts.IOutletReportingContract_v2" />
    <endpoint address="mex" binding="mexHttpsBinding" name="IMetadataExchange" contract="IMetadataExchange" />
  </service>
</services>
