這篇文章主要介紹了jQuery實現ajax調用WCF服務的方法,以完整實例形式分析了jQuery的ajax前端調用及後台交互調用WCF服務的相關技巧,並附帶完整實例共讀者下載,需要的朋友可以參考下方
本文實例講述了jQuery實作ajax呼叫WCF服務的方法。分享給大家參考，具體如下：
關於AJAX呼叫WCF服務分為跨域與不跨域兩種方式，今天咱們先介紹下不跨域下的呼叫方法。 DEMO是在VS2008寫的.
經過測試與研究，發現AJAX調用WCF服務必須滿足以下條件
1.wcf的通訊方式必須使用webHttpBinding
2.必須設定< ;endpointBehaviors>節點的值
3.服務的實作必須新增標記
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
4.方法前面必須加入如下標記
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
5.ajax方法中傳遞的參數名稱必須和wcf服務中提供的參數方法名稱一致
以下是本人寫的程式碼，標記顏色的是需要注意的地方
伺服器端設定檔代碼
<system.serviceModel>
<services>
<service name="WcfServiceDemoOne.Service1" behaviorConfiguration="WcfServiceDemoOne.Service1Behavior">
<!-- Service Endpoints -->
<endpoint address="" binding="webHttpBinding" contract="WcfServiceDemoOne.IService1" behaviorConfiguration="HttpBehavior"></endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>

<add baseAddress="http://localhost:12079/Service1.svc"/>

<!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false 并删除上面的元数据终结点-->
<serviceMetadata httpGetEnabled="true"/>
<!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息-->
<serviceDebug includeExceptionDetailInFaults="false"/>

[ServiceContract]
public interface IService1
{
[OperationContract]
string GetData(int value);
[OperationContract]
City GetDataUsingDataContract(City composite);
[OperationContract]
List<City> GetList();
[OperationContract]
List<City> GetListData(List<City> list);
}
// 使用下面示例中说明的数据约定将复合类型添加到服务操作。
[DataContract]
public class City
{
int seq = 0;
string cityID;
string ctiyName;
[DataMember]
public string CityID
{
get
{
return cityID;
}
set
{
cityID=value;
}
}
[DataMember]
public string CityName
{
get { return ctiyName; }
set { ctiyName = value; }
}
[DataMember]
public int Seq
{
get
{ return seq; }
set
{ seq = value; }
}
