Expose WCF Service as SOAP and REST

Expose WCF  Service as SOAP and REST

1) Create WCF Service application

2) Add interface file+Class file+ .svc file

           Interface file:  interface1.cs

           Class file: class1.cs

           Service file: Service2.svc

3)  interface1.cs

using System.ServiceModel;
using System.ServiceModel.Web;
using System.Runtime.Serialization;

namespace WcfService1

{

[ServiceContract]
    interface Interface1
    {
        [WebGet]
        [OperationContract]   
        Person GetPerson();
    }


    [DataContract]
    public class Person
    {
        [DataMember] public int id{get;set;}
        [DataMember] public String Name{get;set;}
        [DataMember] public DateTime Dob{get;set;}
    }
}

}

4) Class1.cs

namespace WcfService1
{
    [ServiceBehavior(IncludeExceptionDetailInFaults=true)]
    public class Class1:Interface1
    {
        public Person GetPerson()
        {
            return new Person { id = 102, Dob = DateTime.Now.AddYears(-40), Name = "Peter"};
        }
    }
}

5) Service2.svc

<%@
    ServiceHost
    Service="WcfService1.Class1"
%>

6) In Web.config

  <system.serviceModel>
    <services>
      <service name="WcfService1.Class1">
        <endpoint binding="webHttpBinding"
                   contract="WcfService1.Interface1"
                   behaviorConfiguration="restBehaviour"

                   address="/web"
                  ></endpoint>
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="restBehaviour">
          <webHttp helpEnabled="true" faultExceptionEnabled="true"/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
  </system.serviceModel>

6)  For SOAP Clients

 Just run   http://localhost:port/Service2.svc

For Rest Services

  http://localhost:port/Service2.svc/web

     User  gets help page and list of operations, in this case GetPerson

7) How to consume WCF Rest Service JSON format

            Uri uri = new Uri("http://localhost:23454/Service2.svc/GetPerson?format=json");

            WebClient client = new WebClient();
            client.Headers.Add(HttpRequestHeader.ContentType, "application/json");

            Stream jsonSTream=
                client.OpenRead(uri);

            StreamReader reader =
                new StreamReader(jsonSTream);

            String strPerson=reader.ReadToEnd();
            Console.WriteLine(strPerson);
            Console.ReadLine();

JSON OUTPUT:

{"Dob":"\/Date(120135205873-0700)\/","Name":"Peterapplication\/json","id":102}

7) How to consume WCF Rest Service XML format

            Uri uri = new Uri("http://localhost:23454/Service2.svc/GetPerson?format=xml");

            WebClient client = new WebClient();
            client.Headers.Add(HttpRequestHeader.ContentType, "text/xml");

            Stream jsonSTream=
                client.OpenRead(uri);

            StreamReader reader =
                new StreamReader(jsonSTream);

            String strPerson=reader.ReadToEnd();
            Console.WriteLine(strPerson);
            Console.ReadLine();

XML Output:

<Person xmlns="http://schemas.datacontract.org/2004/07/WcfService1" xmlns:i="htt
p://www.w3.org/2001/XMLSchema-instance"><Dob>1973-10-22T03:53:29.6915206-07:00</
Dob><Name>Petertext/xml</Name><id>102</id></Person>

Create and consume Jsonp Service using WCF Rest Service

Create and consume Jsonp Service using WCF Rest Service

1) Create WCF Rest Service 

   Create a WCF Service Application

               Delete all existing files then add below files.

    1.1 ) Create a Data Contract called Person

     [DataContract]
    public class Person
    {
        [DataMember] public int id{get;set;}
        [DataMember] public String Name{get;set;}
        [DataMember] public DateTime Dob{get;set;}
    }

    1.2) Expose this using Service Contract

         [ServiceContract]
    interface Interface1
    {
        [WebGet(ResponseFormat=WebMessageFormat.Json)]
           
        Person GetPerson();
    }

1.3)  Implement this interface

namespace WcfService1
{
    [ServiceBehavior(IncludeExceptionDetailInFaults=true)]
    [JavascriptCallbackBehavior(UrlParameterName="$callback")]
[AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Allowed)]
    public class Class1:Interface1
    {
        public Person GetPerson()
        {
            return new Person { id = 102, Dob = DateTime.Now.AddYears(-40), Name = "Peter"};
        }
    }
}

JavascriptCallbackBehavior Attribute specifies actual Callback parameter. in this case "callback"

1.4)  Enable Cross Domain Script Access in Web.config

<system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="mywebb" crossDomainScriptAccessEnabled="true">
         
        </binding>
      </webHttpBinding>
    </bindings>
    <services>
      <service name="WcfService1.Class1">
        <endpoint binding="webHttpBinding" bindingConfiguration="mywebb" contract="WcfService1.Interface1" behaviorConfiguration="restBehaviour"/>
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="restBehaviour">
          <webHttp helpEnabled="true" faultExceptionEnabled="true"/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>

1.5) Specify Host factory as WebServiceHostFactory in Service2.svc

<%@
    ServiceHost
    Factory="System.ServiceModel.Activation.WebServiceHostFactory"
    Service="WcfService1.Class1"
%>

1.6)Just Run the Service2.svc 

U will see help page and list of Operations


     

  

           
 

2) using javascript Consume Jsonp Rest Service

  2.1) Create a new Empty asp.net Web Application or Simply Html Page


2.2) Add a Callback function

              <script type="text/javascript">
                function fun1(persondata) {

                    alert("Name="+persondata.Name+
                           "Id=" + persondata.id+
                           "DOB=" + persondata.Dob);

                }

    </script>


2.3)  Call   WCF Service URL  using Script tag



<script type="text/javascript" src="http://localhost/WcfService1/Service2.svc/GetPerson?$callback=fun1"></script>

Just  run the web page

U will get

3) How to COnsume WCF REST jsonp service in JQUERY ajax

<script type="text/javascript">
     $(document).ready(function () {
     
         $.ajax({
             url: 'http://localhost/WcfService1/Service2.svc/GetPerson?$callback=localJsonpCallback',
             type: "GET",
             async: false,
             crossDomain: true,
             cache: false,
             jsonp: true,
             dataType: "jsonp",
         });
         //).done(function (data) {
         //    alert(data.Name);
         //}).fail(function (jqXHR, textStatus)
         //{
         //    alert(textStatus+jqXHR.status);
         //});
         //jsonpCallback: function (data) {
         //    alert(data + "callback");
         //}
    
     });
 </script>
    <script type="text/javascript">
        function localJsonpCallback(data) {
            alert(data.Name+" "+data.id+" "+data.Dob);
        }

    </script>

Self Hosting WCF Service VB.NET

Self Hosting WCF Service in Console Applictaion Vb.NET

1) Create Contract and Implementation

     Here I use ADO.NET connecting to Northwind Database to get Number of Orders.

2) In Program Entry.

              Create Service Host  

3) Using ChannelFactory query above WCF Service

ServiceContract

    <ServiceContract> _
    Public Interface IOrder
        <OperationContract> _
        Dim GetOrderCount() As Integer
    End Interface

Implementation Class for Service Contract

Service Contract has single method called GetOrderCount from NorthWind Database.

 

    Public Class Orders
     Implements IOrder
        Public Function GetOrderCount() As Integer
            SqlConnection conn = New
                SqlConnection("Data Source=localhost\sqlexpress2012;Initial Catalog=northwind;trusted_connection=yes;")
            conn.Open()

            Dim cmd As SqlCommand =  New SqlCommand("select count(*) from orders",conn)
            Dim obj As Object = cmd.ExecuteScalar()

           Return Int32.Parse(obj.ToString())
        End Function
    End Class
 
In Program Entry Point

                1) Create/Host a WCF Service  assign some port number(unused) here

                 2) Consume same service using ChannelFactory

                1) Create/Host a WCF Service  assign some port number(unused) here

                'Create or Host WCF Service Here
                Dim baseAdd() As Uri =  New Uri() {New Uri("http://localhost:7070/")}

                Dim host As ServiceHost =  New ServiceHost(Type.GetType(Orders),baseAdd)
                host.AddServiceEndpoint(Type.GetType(IOrder), New WSHttpBinding(),
                "http://localhost:7070/selfhost")

                Dim mb As ServiceMetadataBehavior =  New ServiceMetadataBehavior()
                mb.HttpGetEnabled = True
                host.Description.Behaviors.Add(mb)

                'Open the Service
                host.Open()

 

                 2) Consume same service using ChannelFactory

               //Consume the above WCF Service using ChannelFactory
                 'Consume the above WCF Service using ChannelFactory
                '
                Dim binding As WSHttpBinding =  New WSHttpBinding()
                Dim address As EndpointAddress =  New EndpointAddress(
                "http://localhost:7070/selfhost")

                Dim channel As selfhostwcf.IOrder =  New ChannelFactory
                <selfhostwcf.IOrder>(binding,address).CreateChannel()
                Console.WriteLine("Order Count={0}",channel.GetOrderCount())

                Console.ReadLine()

That's it ,Hosting and consuming WCF service in console application without web.config settings.

Type :  
http://localhost:7070/  in your browser u will see metadata.

as long as console application is running you can access service metdata and other applications also can consume this service.

After Excuting Console Application U will get Output as

Order Count=830
