Question

我为客户端创建了一个WCF服务，以便与ASP.NET应用程序通信。该服务是在客户端上创建的，ASP.NET应用程序可以调用该服务。现在我在沟通时没有使用安全措施。

到目前为止，服务已创建并正在运行。 ASP.NET应用程序为它创建了一个ServiceReference，但在尝试调用方法时，我收到以下错误消息（调试开启）：

带有Action＆＃39; http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue＆＃39;的消息由于EndpointDispatcher上的ContractFilter不匹配，无法在接收方处理。这可能是由于合同不匹配（发送方与接收方之间的操作不匹配）或发送方与接收方之间的绑定/安全性不匹配。检查发件人和收件人是否具有相同的合同和相同的绑定（包括安全要求，例如消息，传输，无）。

足够简单，app.config问题。我似乎无法找出问题是什么，因为我已经将app.config从WCF主机复制到了ASP。应用

客户端的App.config（WCF主机）：

<system.serviceModel>
<bindings>
<wsHttpBinding>
  <binding name="WSHttpBinding_Interface" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="infinite" sendTimeout="00:01:00" 
           bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
           messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    <reliableSession ordered="true" inactivityTimeout="infinite" enabled="false" />
      <security mode="None">
      </security>
  </binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8732/WCF/" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_Interface" contract="WCFProject.IInterface" name="WSHttpBinding_Interface">
  <identity>
    <dns value="localhost" />
  </identity>
</endpoint>
</client>
<services>
<service name="WCFProject.Interface" behaviorConfiguration="WCFProject.InterfaceBehavior">
  <endpoint address="" binding="wsHttpBinding" contract="WCFProject.IInterface" bindingConfiguration="WSHttpBinding_Interface" name="WCFProject.Interface.EndpointConfiguration">
    <identity>
      <dns value="localhost" />
    </identity>
  </endpoint>
  <!-- Metadata Endpoints -->
  <!-- The Metadata Exchange endpoint is used by the service to describe itself to clients. -->
  <!-- This endpoint does not use a secure binding and should be secured or removed before deployment -->
  <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
  <behavior name="WCFProject.InterfaceBehavior">
    <!-- To avoid disclosing metadata information, 
      set the value below to false and remove the metadata endpoint above before deployment -->
    <serviceMetadata httpGetEnabled="True" />
    <!-- To receive exception details in faults for debugging purposes, 
      set the value below to true.  Set to false before deployment 
      to avoid disclosing exception information -->
    <serviceDebug includeExceptionDetailInFaults="True" />
  </behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>

ASP应用程序的App.config（ServiceReference名为InterfaceService）：

<system.serviceModel>
<bindings>
<wsHttpBinding>
  <binding name="WSHttpBinding_Interface" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="infinite" sendTimeout="00:01:00" 
           bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 
           messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    <reliableSession ordered="true" inactivityTimeout="infinite" enabled="false" />
      <security mode="None">
      </security>
  </binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8732/WCF/" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_Interface" contract="InterfaceService.IInterface" name="WSHttpBinding_Interface">
  <identity>
    <dns value="localhost" />
  </identity>
</endpoint>
</client>
</system.serviceModel>

WCF服务在ASP应用程序中启动，如下所示，其中WCFUrl是WCF服务的URL：

            //Create object of the Binding
        System.ServiceModel.Channels.Binding binding = new System.ServiceModel.WSHttpBinding();
        //Create endpointAddress of the Service
        System.ServiceModel.EndpointAddress endpointAddress = new
        System.ServiceModel.EndpointAddress(WCFUrl + "?wsdl");
        //Create Client of the Service
        InterfaceService.InterfaceClient cc = new InterfaceService.InterfaceClient(binding, endpointAddress);
        //Call Service method using ServiceClient
        string ss = cc.Ping();

任何帮助我指向正确方向的帮助都是适当的。我已经被困在这几天了。感谢。

更新：我还在双方都添加了以下内容：

       <security mode="None">
        <transport clientCredentialType="None"/>
        <message establishSecurityContext="false"/>
      </security>

这没有运气。

Answer 1

我认为您需要在客户端配置中配置绑定安全性的所有属性，以匹配服务器发送的内容。

<security>
    <transport/>
    <message/>
 </security>

Answer 2

我的问题是我在端点下面缺少端点地址（http://local.host:8732/WCF/）。那令人尴尬。

感谢。
