我的WCF JSONP Web服务遇到了“有趣”的错误。它是我唯一拥有的,它只暴露一种方法。如果我通过网络浏览器在内部点击我的服务,它会弹出一条消息,实际上,MEX未启用(true)。如果我从我们的网络外部点击它(就像你在我公司的机器上那样),它只是坐着,最后超时。该网址为:http://demo.rivworks.com/services/Negotiate.svc。关于可能导致这种行为的任何想法?
这是web.config:
<!-- WCF configuration -->
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="JsonpServiceBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
<services>
<service name="RivWorks.Web.Service.NegotiateService">
<endpoint address=""
binding="customBinding"
bindingConfiguration="jsonpBinding"
behaviorConfiguration="JsonpServiceBehavior"
contract="RivWorks.Web.Service.INegotiateService" />
</service>
</services>
<extensions>
<bindingElementExtensions>
<add name="jsonpMessageEncoding" type="RivWorks.Web.Service.JSONPBindingExtension, RivWorks.Web.Service, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
</bindingElementExtensions>
</extensions>
<bindings>
<customBinding>
<binding name="jsonpBinding" >
<jsonpMessageEncoding />
<httpTransport manualAddressing="true"/>
</binding>
</customBinding>
</bindings>
</system.serviceModel>
</configuration>
以下是代码:
namespace RivWorks.Web.Service
{
//----------------------------------------------------------------------------------------------------------//
// Data class //
//----------------------------------------------------------------------------------------------------------//
[DataContract(Name = "NegotiateSetup", Namespace = "http://rivworks.com/DataContracts/2009/01/15")]
public class NegotiateSetup : INegotiationInitialize
{
#region Declarations
...
#endregion
#region INegotiationInitialize Members
...
#endregion
}
//----------------------------------------------------------------------------------------------------------//
// Service Implementation //
//----------------------------------------------------------------------------------------------------------//
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class NegotiateService : INegotiateService
{
public NegotiateService() { }
public INegotiationInitialize GetSetup(string method, string jsonInput)
{
...
return resultSet;
}
}
}
我在这里做了几件事:
注意:我使用的是此处的JSONP类:http://msdn.microsoft.com/en-us/library/cc716898.aspx
答案 0 :(得分:0)
要启用MEX,请在service
标记内添加:
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
在behaviors
标记内添加:
<serviceBehaviors>
<behavior name="JsonpServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
关于无法从外部访问该服务的原因,这可能是防火墙问题吗?
