如何通过WCF在C＃中公开SOAP Web服务

Question

For my project at school I must create some SOAP web services with WCF in a C# app, in order to make it interact with a Java EE app.

I can't find any tutorial telling me how to do this with WCF. What should I do?

Answer 1

REST / SOAP endpoints for a WCF service

You can expose the service in two different endpoints. the SOAP one can use the binding that support SOAP eg basicHttpBinding, the RESTful one can use the webHttpBinding. I assume your REST service will be in JSON, in that case, you need to configure the two endpoints with the following behaviour configuration

<endpointBehaviors>
    <behavior name="jsonBehavior">
        <enableWebScript/>
    </behavior>
</endpointBehaviors>

An example of endpoint configuration in your scenario is

<services>
    <service name="TestService">
        <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
        <endpoint address="json" binding="webHttpBinding"  behaviorConfiguration="jsonBehavior" contract="ITestService"/>
    </service>
</services>

so, the service will be available at
http://www.example.com/soap http://www.example.com/json
Apply [WebGet] to the operation contract to make it RESTful. eg

public interface ITestService { [OperationContract] [WebGet] string HelloWorld(string text) }

Note, if the REST service is not in JSON, parameters of the operations can not contain complex type.
For plain old XML as return format, this is an example that would work both for SOAP and XML.

[ServiceContract(Namespace = "http://test")]
public interface ITestService
{
[OperationContract]
[WebGet(UriTemplate = "accounts/{id}")]
Account[] GetAccount(string id);
}

POX behavior for REST Plain Old XML

<behavior name="poxBehavior">
    <webHttp/>
</behavior>

<services>
    <service name="TestService">
        <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
        <endpoint address="xml" binding="webHttpBinding"  behaviorConfiguration="poxBehavior" contract="ITestService"/>
    </service>
</services>

http://www.example.com/soap http://www.example.com/xml
REST request try it in browser,
http://www.example.com/xml/accounts/A123

<client>
    <endpoint address="http://www.example.com/soap" binding="basicHttpBinding"
  contract="ITestService" name="BasicHttpBinding_ITestService" />
</client>

TestServiceClient client = new TestServiceClient();
client.GetAccount("A123");

Another way of doing it is to expose two different service contract and each one with specific configuration. This may generate some duplicates at code level, however at the end of the day, you want to make it working.

Answer 2

Just create a WCF project in Visual Studio, and write all the code in C#. The actual problem you're going to have is making SOAP calls from Java EE.

The WCF service will be hosted in IIS not a Windows Service hosting WCF.
