IIS中的多个wcf服务

Question

我试图在IIS下运行多个WCF服务，使用相同的基本URL (因此我的项目有多个.svc文件)。当我有一个服务时，一切都很好，但是当我添加额外的服务时，问题就出现了。当我尝试访问这些附加服务时，客户似乎认为合同是"IMerchantService“合同。例如，如果我浏览到http://merchants.localtest.me/MerchantProductService.svc?wsdl (本地托管服务的地址)，返回的服务定义是IMerchantService而不是IMerchantProductService。此外，当我浏览到http://merchants.localtest.me/MerchantProductService.svc时，标题是"MerchantService“，而不是我所期望的"MerchantProductService”。

我的服务配置如下：

  <services>
  <service name="MyCompany.Services.Merchants.MerchantProductService">
    <endpoint address="" behaviorConfiguration="Proto.Common.EndpointBehavior" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_Common" contract="MyCompany.Api.Merchants.Services.IMerchantProductService"/>
    <endpoint address="mexMerchantProductService"
          binding="mexHttpBinding"
          contract="IMetadataExchange" />
  </service>
  <service name="MyCompany.Services.Merchants.MerchantService">
    <endpoint address="" behaviorConfiguration="Proto.Common.EndpointBehavior" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_Common" contract="MyCompany.Api.Merchants.Services.IMerchantService"/>
    <endpoint address="mexMerchantService"
          binding="mexHttpBinding"
          contract="IMetadataExchange"  />
  </service>
  <service name="MyCompany.Services.Merchants.Workflows.NewMerchantWorkflow">
    <endpoint address="" behaviorConfiguration="Proto.Common.EndpointBehavior" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_Common" contract="MyCompany.Api.Merchants.Services.INewMerchantServiceWorkflow"/>
    <endpoint address="mexNewMerchantWorkflow"
  binding="mexHttpBinding"
  contract="IMetadataExchange" />
  </service>
  <service name="MyCompany.Services.Merchants.MerchantFreightService">
    <endpoint address="" behaviorConfiguration="Proto.Common.EndpointBehavior" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_Common" contract="MyCompany.Api.Merchants.Services.IMerchantFreightService"/>
    <endpoint address="mexMerchantFreightService"
  binding="mexHttpBinding"
  contract="IMetadataExchange" />
  </service>
  <service name="MyCompany.Services.Merchants.MerchantAuctionService">
    <endpoint address="" behaviorConfiguration="Proto.Common.EndpointBehavior" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_Common" contract="MyCompany.Api.Pricing.Services.IMerchantAuctionService"/>
    <endpoint address="mexMerchantAuctionService"
  binding="mexHttpBinding"
  contract="IMetadataExchange" />
  </service>
</services>

我尝试过移除额外的mex端点，但这并没有什么区别。另外，我检查了合同，在我看来，它们看上去还不错。IMerchantProductService合同如下：

[ServiceContract(Namespace = "http://www.MyCompany.com/services/", Name = "MerchantProductService")]
[ContractClass(typeof(MerchantProductServiceContracts))]
public interface IMerchantProductService
{
    /// <summary>
    /// Searchs the merchants product catalog using product name, merchant sku or product global id
    /// </summary>
    /// <param name="searchTerm"></param>
    /// <returns></returns>
    [OperationContract]
    List<MerchantProductQuickSearchItem> QuickSearchMerchantProducts(int merchantId, string searchTerm);

    /// <summary>
    /// Gets a merchant product based on the Id
    /// </summary>
    /// <param name="ourMerchantProductId">The id of the product to get</param>
    /// <returns></returns>
    [OperationContract]
    MerchantProduct GetMerchantProduct(int ourMerchantProductId, int merchantId);

    ///etc.

}

IMerchantService的合同如下：

[ServiceContract(Namespace = "http://www.MyCompany.com/services/", Name = "MerchantService")]
[ContractClass(typeof(MerchantServiceContracts))]
public interface IMerchantService
{
    /// <summary>
    /// Gets a merchant instance
    /// </summary>
    /// <param name="merchantId"></param>
    /// <returns></returns>
    [OperationContract]
    Merchant GetMerchant(int merchantId);

    /// <summary>
    /// Gets a merchant's bid settings
    /// </summary>
    /// <param name="merchantId"></param>
    /// <returns></returns>
    [OperationContract]
    MerchantBidSettings GetMerchantBidSettings(int merchantId);

    //etc.
}

到目前为止我尝试过的事情：

1. 将所有内容更改为basicHttpBinding。没什么区别。
2. 删除Protobuf行为配置。没什么区别。
3. 删除单个mex端点。没什么区别
4. 尝试不同的客户端(WCFStorm，WCF测试客户端)并报告错误的合同
5. 检查各个svc文件是否正在实现预期的契约(它们是)。

我想我的问题是( 1)这是否可能(即多个.svc文件与IIS托管)，如果是的话，我的配置是否有问题，可能导致我的问题。

Answer 1

检查每个.svc文件的内容。您是否引用正确的服务实现？您需要web.config + .svc文件+ c#契约定义+ c#服务实现来实现它。

<%@ ServiceHost 
    Language="C#"
    Debug="true"
    Service="MyCompany.Services.Merchants.MerchantService" %>
