使简单的WCF服务正常工作的问题

Question

I am having a frustrating time getting both POST and GET running on my webservice. I need to stop, chill out and figure out what is going wrong.

I broke it down to a very simple method that just takes a string and echos it back. This works on the IIS I have set on my localhost, it works on the production box, but the same configuration is breaking on my test system. Please let me know what I am doing wrong. When accessing:

http://test.softwaredesignexcellence.com/WebPostService/WebPostSvc.svc/json/Test?testtext=test%20me

I am getting a page with a bold header with the text "Service" and the sub header in smaller text stating "Endpoint not found.". Why am I getting this message? The same service works on my local host using the query string "http://localhost/Services/WebPostSvc.svc/json/Test?testtext=test%20me". and I'm getting the response:

<string>Echoing test me</string>

The production server, which I can't put a link to, since it is internal is giving a slightly different response, but it's still working fine:

 <string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">Echoing test me</string>

It is frustrating when I publish locally, hit the local web server, everything is working. I copy the published folder to the production server, type in the similar URL on that server, everything is working, then I ftp the same code, and the same settings to my test server, and it is breaking with the error listed above (Endpoint not found.). What am I not understanding that is keeping me from getting a simple service to run on the test server?

The Interface for the web service:

    [ServiceContract( Namespace="http://services.alorica.com/WebPostSvc/1.0" )]
    public interface IWebPostSvc
    {
        [OperationContract]
        [WebGet]
        string Test(string testtext);
    }

This is the simple method I am trying to get working:

    [WebService(Namespace = "http://services.alorica.com/WebPostSvc/1.0")]
    [ServiceBehavior(Namespace = "http://services.alorica.com/WebPostSvc/1.0")]
    public class WebPostSvc : IWebPostSvc
    {
        public string Test(string testtext)
        {
             return String.Format("Echoing {0}", testtext);
        }
    }

My settings are getting unweildy, as I have been fiddling with them trying to get everything working. UPDATE - I just removed the serviceHostingEnvironment section, it didn't seem to be necessary, Web Service is still up and working with SOAP, but json is still giving me "Endpoint not found".

Answer 1

Your service does not have any host defined in the endpoints.

 <services>
  <service name="WebPostService.WebPostSvc">
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="SOAPBinding" name="serviceBasicHttpBinding" contract="WebPostService.IWebPostSvc">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <host>
      <baseAddresses>
        <add baseAddress="http://test.softwaredesignexcellence.com" />
      </baseAddresses>
    </host>
  </service>
     </services>

Answer 2

Try to add UriTemplate to WebGet. Actually you should use WebInvoke for POST.

Answer 3

Thank you, those that answered so quickly. I found my particular issue, it wasn't in the configuration as I had thought.

The server I was publishing to did not have .NET 3.5 installed, which is fine, because .NET 2.0 will suffice, but it was missing assemblies. I don't know why I didn't get a better error message, but the solution was to look through my references, and switch them to "Copy Local" and do a republish, after which everything was working on that server. I did the "Copy Local" on all the references out of frustration, but I'm sure I only needed to do this to the ones that were not included in the .NET 2.0 framework.
