We have previously introduced Step by Step to create a WCF Service and use the Trace and Message Log functions of WCF. This article describes how to use JavaScript to call the WCF Service.
The code for the WCF Service is as follows:
IHelloService. cs
using System.ServiceModel;using System.ServiceModel.Activation;using System.ServiceModel.Web;namespace HelloService{ [ServiceContract(Name = "IHelloService")] public interface IHelloService { [OperationContract(Name="GetMessage")] string GetMessage(string name); [OperationContract] Employee GetEmployee(int id); }}
HelloService. cs
using System;namespace HelloService{ public class HelloService : IHelloService { public string GetMessage(string name) { return "Hello " + name; } public Employee GetEmployee(int id) { return new Employee() { Id = id, Name="Neil Klugman", Birthdate=new DateTime(1930, 1, 31)}; } }}
In the web. config file, pay attention to the highlighted part:
<?xml version="1.0" encoding="utf-8" ?><configuration> <system.serviceModel> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> <services> <service name="HelloService.HelloService" behaviorConfiguration="metaBehavior"> <endpoint address="" binding="webHttpBinding" contract="HelloService.IHelloService" behaviorConfiguration="ajaxServiceBehavior"></endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
Create a client web application and add a web form, WebForm1.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="HelloWebClient.WebForm1" %><!DOCTYPE html>
Open WebForm1.aspx in a browser and use Fiddler to view it, because the Code contains a reference to the WCF Service.
<Asp: ServiceReference Path = "http: // 192.168.6.47: 8080/HelloService. svc"/>
So the page loads JavaScript
