我在使用 jquery 从 WCF 服务检索结果时遇到了问题。我在 IIS 中托管 WCF 服务，当我将调试器附加到此进程时，我可以看到代码已成功处理。但是，当它命中 jquery 中的回调时，没有数据？？
我已经在 wcf 服务上设置了跟踪并且没有错误。似乎在 wcf 服务方法完成后数据丢失了。
这里是调用服务的 jquery 代码:
$.get("http://ecopssvc:6970/ecopsService.svc/Echo", {echoThis: "please work"}, function(data) {
alert("Data Loaded: " + data);
});
这是 wcf 配置:
<system.serviceModel>
<services>
<service name="EcopsWebServices.EcopsService" behaviorConfiguration="EcopsServiceBehaviours">
<endpoint address="" behaviorConfiguration="WebBehaviour"
binding="webHttpBinding" bindingConfiguration="" contract="EcopsWebServices.IEcopsServiceContract" />
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="WebBehaviour">
<webHttp />
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="EcopsServiceBehaviours">
<serviceMetadata httpGetEnabled="true" httpGetUrl=""/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
这是服务契约(Contract):
[ServiceContract]
public interface IEcopsServiceContract
{
[WebGet]
[OperationContract]
string Echo(string echoThis);
}
这是服务实现:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class EcopsService : IEcopsServiceContract
{
#region IEcopsServiceContract Members
public string Echo(string echoThis)
{
return string.Format("You sent this '{0}'.", echoThis);
}
#endregion
}
请帮助某人!!!
最佳答案
确保将出厂设置为 WebScriptServiceHostFactory在您的 .svc 标记中。还要确保 WCF 服务和网页遵守 same origin policy .这是一个完整的工作示例:
WCF 服务:
[ServiceContract]
public interface IService1
{
[WebGet]
[OperationContract]
string Echo(string echoThis);
}
public class Service1 : IService1
{
public string Echo(string echoThis)
{
return string.Format("You sent this '{0}'.", echoThis);
}
}
网络配置:
<system.serviceModel>
<services>
<service name="ToDD.Service1"
behaviorConfiguration="ToDD.Service1Behavior">
<endpoint address=""
binding="webHttpBinding"
contract="ToDD.IService1" />
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ToDD.Service1Behavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
服务1.svc:
<%@ ServiceHost
Language="C#"
Debug="true"
Service="ToDD.Service1"
CodeBehind="Service1.svc.cs"
Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory"
%>
