IApiService.cs

[ServiceContract]
public interface IApiService
{
    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    Boolean TestConnection();

    [OperationContract]  
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    Boolean IsPhoneNumberListMatch(int pa, int pb);

    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    List<ClientPhoneModel> GetAllPhoneNumber(string pa);

    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    List<ClientRegistrationModel> GetAllNewRegistration(string pa);
}

web.config

<system.serviceModel>
    <behaviors>
        <endpointBehaviors>
        <behavior name="EndBehavior">
            <webHttp />
        </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
        <behavior name="ServiceBehavior">
            <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
            <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
    </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="ServiceBehavior" name="ApiService">
            <endpoint address="basic" binding="webHttpBinding" contract="IApiService" behaviorConfiguration="EndBehavior"/>
        </service>
        <service behaviorConfiguration="ServiceBehavior" name="WebService">
            <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="EndBehavior"/>
        </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>

Window Application

Added localhost:5151/ApiService.svc as Service Reference

Index.cs

try {
    Localhost.ApiServiceClient client = new Localhost.ApiServiceClient();
    client.TestConnection();
}
catch(Exception ex) {
    Log.Exception(ex);
}

App.config

<system.serviceModel>
    <behaviors>
        <serviceBehaviors>
                <behavior name="ServiceBehavior">
                    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="true"/>
                </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
            <behavior name="EndBehavior">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
    <client>
        <endpoint address="http://localhost:5151/ApiService.svc" behaviorConfiguration="EndBehavior" binding="webHttpBinding" contract="Localhost.IApiService" name="ApiServiceClient" />
    </client>
</system.serviceModel>

The latest error I could get is

Message : 
    Operation 'IsPhoneNumberListMatch' of contract 'IApiService' specifies multiple request body parameters to be serialized without any wrapper elements. At most one body parameter can be serialized without wrapper elements. Either remove the extra body parameters or set the BodyStyle property on the WebGetAttribute/WebInvokeAttribute to Wrapped.

Please help me~~~ million thanks

Answer 1

This may not be the answer you wanted, but I suggest not having multiple parameters on your operations when having to provide a non-soap binding. The primary reason for this is that by only using the "Bare" bodyStyle, you can get a nice help-page. Try setting:

<behaviors>
  <endpointBehaviors>
    <behavior name="EndBehavior">
      <webHttp automaticFormatSelectionEnabled="true" defaultBodyStyle="Bare" helpEnabled="true"/>
    </behavior>
  </endpointBehaviors>
</behaviors>

This will:

1. Let the user decide if they want to communicate using json or xml
   (automaticFormatSelectionEnabled)
2. Set a default BodyStyle
3. Enable the help page

If you do this, you can delete all your WebInvoke attributes: [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]

You can find the help-page at: http://your.domain/servicename/endpointAddress/help So if I have a service called Engine.svc at service.motor.car and my endpoint address is "v1/web" I would find my help-page at http://service.motor.car/Engine.svc/v1/web/help

Hope this helps :-)
