本次程序和上一节程序类似,只是为WCF服务创建了接口。
Demo:请点击这里
直接看下代码吧。
Service1.svc.cs代码:
using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Activation; using System.ServiceModel.Web; using System.Text; namespace WebApplication1 { [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] //这里必须写命名空间,不要空着 [ServiceContract(Namespace = "GLM")] public class Service1 : IService1 { // 要使用 HTTP GET,请添加 [WebGet] 特性。(默认 ResponseFormat 为 WebMessageFormat.Json) // 要创建返回 XML 的操作, // 请添加 [WebGet(ResponseFormat=WebMessageFormat.Xml)], // 并在操作正文中包括以下行: // WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml"; [OperationContract] public string SayHello(string name) { // 在此处添加操作实现 return string.Format("hello,name={0}",name); } } public interface IService1 { string SayHello(string name); } }
Service1.svc代码:
<%@ ServiceHost Language="C#" Debug="true" Service="WebApplication1.Service1" CodeBehind="Service1.svc.cs" %>
WebForm1.aspx代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script type="text/javascript"> function test() { var client = new GLM.Service1(); var strName = "Jack"; client.SayHello(strName,OnComplete,OnError); } function OnComplete(result) { alert(result); } function OnError(result) { alert("Error"); } </script> </head> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> <Services> <asp:ServiceReference Path="~/Service1.svc" /> </Services> </asp:ScriptManager> <div> <input id="button1" type="button" value="click" onclick="test();" /> </div> </form> </body> </html>
好吧,问题已经解决,刚才查看了以下配置文件,发现问题所在了,如果想将OperationContract和ServiceContract用在接口上,必须修改配置文件的endPoint节点的contract属性,该节点原来是这样的:
<services> <service name="WebApplication1.Service1"> <endpoint address="" behaviorConfiguration="WebApplication1.Service1AspNetAjaxBehavior" binding="webHttpBinding" contract="WebApplication1.Service1" /> </service> </services>
修改成这样就OK了:
<services> <service name="WebApplication1.Service1"> <endpoint address="" behaviorConfiguration="WebApplication1.Service1AspNetAjaxBehavior" binding="webHttpBinding" contract="WebApplication1.IService1" /> </service> </services>
现在,Service1.svc.cs文件就是这样了:
using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Activation; using System.ServiceModel.Web; using System.Text; namespace WebApplication1 { [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class Service1 : IService1 { // 要使用 HTTP GET,请添加 [WebGet] 特性。(默认 ResponseFormat 为 WebMessageFormat.Json) // 要创建返回 XML 的操作, // 请添加 [WebGet(ResponseFormat=WebMessageFormat.Xml)], // 并在操作正文中包括以下行: // WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml"; public string SayHello(string name) { // 在此处添加操作实现 return string.Format("hello,name); } } //这里必须写命名空间,不要空着 [ServiceContract(Namespace = "GLM")] public interface IService1 { [OperationContract] string SayHello(string name); } }
注意在WebForm1.aspx中调用服务的时候,要修改成:
<script type="text/javascript"> function test() { var client = new GLM.IService1();//看这里 var strName = "Jack"; client.SayHello(strName,OnError); } function OnComplete(result) { alert(result); } function OnError(result) { alert("Error"); } </script>原文链接:https://www.f2er.com/ajax/164925.html
