WCF service returns 404 over https but not http

问题

I'm migrating an existing service from HTTP (Dev/UAT) to HTTPS (Production), and I'm having trouble with the configuration. Here is the system.serviceModel section of my web.config:

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
    <services>
      <service name="MyService">
        <endpoint name="MyEndpoint" address="" binding="wsHttpBinding"
            bindingConfiguration="secureBinding" contract="IMyService" />
      </service>
    </services>
    <bindings>
      <wsHttpBinding>
        <binding name="secureBinding">
          <security mode="Transport"></security>
        </binding>
      </wsHttpBinding>
    </bindings>
</system.serviceModel>

I've tried this using both basicHttpBinding and wsHttpBinding, with the same results:

• I can call the service from my SOAP client using http://server.domain.com/MyService.svc
• I can hit the service from a browser using https://server.domain.com/MyService.svc
• I can't call the service from my SOAP client using https://server.domain.com/MyService.svc - the call always errors with 404: not found.

My https site is certified using a certificate that was issued by a CA on the corporate domain, and I've verified that I have that CA's certificate installed in Trusted Root Certification Authorities on the system from which I'm making the calls.

The relevant client code:

Service service = new Service();
service.Url = "http://server.domain.com/MyService.svc";
//service.Url = "https://server.domain.com/MyService.svc";
service.WebMethodCall();

EDIT

Here are the requested portions of the WSDL:

<wsdl:types/>
<wsdl:portType name="IMyService"/>
<wsdl:binding name="BasicHttpBinding_IMyService" type="tns:IMyService">
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
</wsdl:binding>
<wsdl:service name="MyService">
    <wsdl:port name="BasicHttpBinding_IMyService" 
        binding="tns:BasicHttpBinding_IMyService">
        <soap:address location="http://server.domain.com/MyService.svc"/>
    </wsdl:port>
</wsdl:service>

EDIT

More information:

When I change the serviceMetadata element to have httpGetEnabled="false" and httpsGetEnabled="true" the .svc page shows me the following link:

https://boxname.domain.com/MyService.svc?wsdl

rather than the expected

https://server.domain.com/MyService.svc?wsdl

回答1:

Check that your service element name in the web.config matches the fully qualified named of the class that implements your contract.

<services>
  <service name="MyNamespace.MyService">
    <endpoint name="MyEndpoint" address="" binding="wsHttpBinding" ...

回答2:

In your WSDL you see that your service does not expose port on HTTPS but only on HTTP. Moreover you can also see that your service uses BasicHttpBinding (see port name and binding name). That means that your service configuration is not used at all. Check that name in the service element is same as name in your .svc markup. It has to be defined including namespaces.

回答3:

HTTP and HTTPS are served from different virtual hosts. Are you sure your service is correctly installed in both?

Thanks to Johann Blais for the answer, I've found out that you would need to include the fully qualified name for the class that defines the service contract.

For example if your service is

namespace MyCompany.WcfService
{

    [ServiceContract(Namespace="http://xsd.mycompany.com/mcy/1_0_0")]
    public interface IService
    {
        [OperationContract(IsOneWay = false)]
        void DoStuff()
    }

    public class Service : IService
    {
        void DoStuff()
        {
        }
    }
}

The corresponding service definition in your web.config would be

<system.serviceModel>
    <services>
        <service name="MyCompany.WcfService.IService">
            <endpoint address="" binding="basicHttpBinding" contract="MyCompany.WcfService.IService" />
        </service>
    </services>
    ...
</system.serviceModel>
