从asp.net访问本地自托管WCF服务网站

Question

我有一个WCF服务库，我在Windows窗体应用程序中托管。我想从一个在azure网站上托管的asp.net网站调用该服务。我在网站项目中创建了一个服务引用，并试图从后面的代码中调用一些服务函数。 当我这样做，我得到以下错误：

An attempt was made to access a socket in a way forbidden by its access permissions 127.0.0.1:8732 
    [SocketException (0x271d): An attempt was made to access a socket in a way forbidden by its access permissions 127.0.0.1:8732] 
     System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) +208 
     System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) +464 

    [WebException: Unable to connect to the remote server] 
     System.Net.HttpWebRequest.GetRequestStream(TransportContext& context) +6543605 
     System.Net.HttpWebRequest.GetRequestStream() +13 
     System.ServiceModel.Channels.WebRequestHttpOutput.GetOutputStream() +55 

    [EndpointNotFoundException: There was no endpoint listening at http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary/ConnectService/ that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.] 
     System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +10818447 
     System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +336 
     TestProject.ConnectServiceReference.IConnectService.SayHello() +0 

我的服务正在运行，我可以在我的浏览器访问该服务的地址。 是否可以通过网站致电该服务？

我的服务配置：

<system.serviceModel> 
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
<services> 
    <service behaviorConfiguration="MyServiceTypeBehaviors" name="WcfServiceLibrary.ConnectService"> 
    <endpoint address="" 
     binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IConnectService" name="ServiceEndpoint" contract="WcfServiceLibrary.IConnectService"> 
     <identity> 
     <dns value="localhost" /> 
     </identity> 
    </endpoint> 
    <endpoint address="mex" binding="mexHttpBinding" name="MetaDataEndpoint" contract="IMetadataExchange" /> 
    <host> 
     <baseAddresses> 
     <add baseAddress="http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary/ConnectService/" /> 
     </baseAddresses> 
    </host> 
    </service> 
</services> 
<bindings> 
    <basicHttpBinding> 
    <binding name="BasicHttpBinding_IConnectService"/>     
    </basicHttpBinding>  
</bindings>  
<behaviors> 
<serviceBehaviors> 
    <behavior name="MyServiceTypeBehaviors" > 
    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> 
     <serviceDebug includeExceptionDetailInFaults="False" /> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 
</system.serviceModel> 

asp.net的web.config：

<bindings> 
    <basicHttpBinding> 
    <binding name="BasicHttpBinding_IConnectService"> 
     <security mode="TransportCredentialOnly"> 
     <transport clientCredentialType="None" proxyCredentialType="Windows" /> 
     </security> 
    </binding> 
    </basicHttpBinding> 
    </bindings> 
<client>  
    <endpoint address="http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary/ConnectService/" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IConnectService" 
    contract="ConnectServiceReference.IConnectService" name="BasicHttpBinding_IConnectService" /> 
</client>

为了确定您所描述的架构，你应该看看Azure服务总线，它允许您在现有（本地）环境中托管WCF服务并将请求委托给这些WCF服务v ia服务总线在Azure中运行。“

以下微软Azure的链接提供您的方案概述：

服务总线中继服务，您可以建立在两个蔚蓝的数据中心和您自己的本地企业环境中运行的混合应用。服务总线中继通过使您能够将位于企业企业网络内的Windows Communication Foundation（WCF）服务安全地公开到公共云而无需打开防火墙连接或要求对企业网络基础架构进行侵入式更改，从而为此提供便利。
