calling a web service using WCF over Http and Https

Question

In our project we have a java web service that runs over http and https. We want to use http internally and https for the external version of our web app.

So we've created the proxy class in our application and we have setup the binding for http in the web/app.config and all works fine.

What changes would we need to make to the code and the configuration to support https for the same service in our external application? If possible please supply code snippets to explain!

Answer 1

I found an answer digging around MSDN.

In my case, I was using a custom binding:

<customBinding>
    <binding name="jsonpBinding">
        <jsonpMessageEncoding/>
        <httpTransport manualAddressing="true"/>
    </binding>
</customBinding>

That was referenced in the service

<services>
    <service name="{YourInfoHere}">
        <endpoint address="" binding="customBinding" bindingConfiguration="jsonpBinding" behaviorConfiguration="{YourInfoHere}" contract="{YourInfoHere}"/>
    </service>
</services>

Adding a second binding that used httpsTransport and then a second service that used that binding did the trick. Final output:

    <services>
        <service name="{YourInfoHere}">
            <endpoint address="" binding="customBinding" bindingConfiguration="jsonpBinding" behaviorConfiguration="{YourInfoHere}" contract="{YourInfoHere}"/>
            <endpoint address="" binding="customBinding" bindingConfiguration="jsonpBindingHttps" behaviorConfiguration="{YourInfoHere}" contract="{YourInfoHere}"/>
        </service>
    </services>
    <bindings>
        <customBinding>
            <binding name="jsonpBinding">
                <jsonpMessageEncoding/>
                <httpTransport manualAddressing="true"/>
            </binding>
            <binding name="jsonpBindingHttps">
                <jsonpMessageEncoding/>
                <httpsTransport manualAddressing="true" />
            </binding>
        </customBinding>
    </bindings>

May not be ideal, but it works. These were the only changes I made to make SSL work. Since it is all in the binding & transport, the code remains the same.

3. HttpsTransport: http://msdn.microsoft.com/en-us/library/system.servicemodel.channels.httpstransportbindingelement.aspx

I am assuming that you are using basichttpbinding. Then you need to do two things:

• change the address to https :)
• set the security mode to transport
