我尝试创建自托管WCF服务，以促进同一台计算机上两个MS-Office插件之间的通信。他们的想法是，他们会在他们之间传递文档元数据。
我一直遇到标题中的错误。
合同/实施：
namespace test.intermediaryservicehost
{
[ServiceContract(SessionMode = SessionMode.Required)]
public interface IIntermediaryObject
{
[OperationContract]
bool GetIsWorking();
[OperationContract]
void SetIsWorking(bool working);
[OperationContract]
Dictionary<string, string> GetDocInfo();
[OperationContract]
void SetDocInfo(Dictionary<string, string> doc_info);
[OperationContract]
Dictionary<string, string> GetIndices();
[OperationContract]
void SetIndices(Dictionary<string, string> index_dict);
}
}
namespace test.intermediaryservicehost
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class IntermediaryObject : IIntermediaryObject
{
private bool isWorking;
private string Doc_Location;
private string Doc_Name;
private string Template_CorrespondenceType;
private string Template_Reference;
private string Template_Type; // "I" == Inbound, "O" == Outbound
private string Template_Name;
public bool GetIsWorking()
{
return this.isWorking;
}
public void SetIsWorking(bool working)
{
this.isWorking = working;
}
public Dictionary<string, string> GetDocInfo()
{
Dictionary<string, string> doc_info = new Dictionary<string, string>();
doc_info.Add("Doc_Location", this.Doc_Location);
doc_info.Add("Doc_Name", this.Doc_Name);
return doc_info;
}
public void SetDocInfo(Dictionary<string, string> doc_info)
{
this.Doc_Location = doc_info["Doc_Location"];
this.Doc_Name = doc_info["Doc_Name"];
}
public Dictionary<string, string> GetIndices()
{
Dictionary<string, string> indices = new Dictionary<string, string>();
indices.Add("Template_CorrespondenceType", this.Template_CorrespondenceType);
indices.Add("Template_Reference", this.Template_Reference);
indices.Add("Template_Type", this.Template_Type);
indices.Add("Template_Name", this.Template_Name);
return indices;
}
public void SetIndices(Dictionary<string, string> indices)
{
this.Template_CorrespondenceType = indices["Template_CorrespondenceType"];
this.Template_Reference = indices["Template_Reference"];
this.Template_Type = indices["Template_Type"];
this.Template_Name = indices["Template_Name"];
}
}
}
这是服务主机的代码（同一项目/命名空间中的窗体）：
private void Form1_Load(object sender, EventArgs e)
{
this.Visible = false;
string svcLocation = "";
try
{
svcLocation = ConfigurationManager.AppSettings["serviceUrl"] == null ? "http://localhost:1112/IntermediaryObject" : ConfigurationManager.AppSettings["serviceUrl"].ToString();
SvcHost = new ServiceHost(typeof(test.intermediaryservicehost.IntermediaryObject), new Uri(svcLocation));
SvcHost.Open();
}
catch (Exception ex)
{
}
}
我在主机的app.config中使用以下配置：
<appSettings>
<add key="serviceUrl" value="http://localhost:1112/IntermediaryObject"/>
</appSettings>
<bindings>
<wsDualHttpBinding>
<binding name="WsHttpBinding_IIntermediaryObject" closeTimeout="00:01:00"/>
</wsDualHttpBinding>
</bindings>
<services>
<service name="test.intermediaryservicehost.IntermediaryObject" behaviorConfiguration="metaDataBehavior">
<endpoint address="http://localhost:1112/IntermediaryObject"
binding="wsDualHttpBinding"
bindingConfiguration="WsHttpBinding_IIntermediaryObject"
contract="test.intermediaryservicehost.IIntermediaryObject"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="metaDataBehavior">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
以下是客户端配置：
<system.serviceModel>
<bindings>
<wsDualHttpBinding>
<binding name="WSDualHttpBinding_IIntermediaryObject" />
</wsDualHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:1112/IntermediaryObject"
binding="wsDualHttpBinding"
bindingConfiguration="WSDualHttpBinding_IIntermediaryObject"
contract="IIntermediaryObject"
name="WSDualHttpBinding_IIntermediaryObject">
</endpoint>
</client>
<diagnostics>
<messageLogging logMessagesAtTransportLevel="true"
logMessagesAtServiceLevel="false"
logMalformedMessages="true"
logEntireMessage="true"
maxSizeOfMessageToLog="65535000"
maxMessagesToLog="1000"/>
</diagnostics>
有关该服务的其他几个事实： 它在ServiceContract上使用SessionMode.Required，因此将存储状态。 ServiceBehavior属性中的实现InstanceContextMode.Single

答案 0 :(得分：0)
这个问题最终成为了约束力。 wsDualHttpBinding要求端点在请求和响应结束时进行侦听。我的客户端应用程序（两个办公室插件）都没有收听任何网址，因此我的错误。怀疑这是CodeCaster试图拖我，踢和尖叫的结论！
我为我的应用程序切换到更合适的绑定; netNamedPipeBinding。
我的新主机配置：
<system.serviceModel>
<bindings>
<netNamedPipeBinding>
<binding name="NetNamedPipeBinding_IIntermediaryObject" closeTimeout="00:01:00"/>
</netNamedPipeBinding>
</bindings>
<services>
<service name="test.intermediaryservicehost.IntermediaryObject" >
<endpoint address="net.pipe://localhost/IntermediaryObject"
binding="netNamedPipeBinding"
bindingConfiguration="NetNamedPipeBinding_IIntermediaryObject"
contract="test.intermediaryservicehost.IIntermediaryObject"/>
<endpoint binding="mexNamedPipeBinding" name="mex" address="mex" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
客户端配置示例：
<system.serviceModel>
<bindings>
<netNamedPipeBinding>
<binding name="NetNamedPipeBinding_IIntermediaryObject" />
</netNamedPipeBinding>
</bindings>
<client>
<endpoint address="net.pipe://localhost/IntermediaryObject" binding="netNamedPipeBinding"
bindingConfiguration="NetNamedPipeBinding_IIntermediaryObject"
contract="IIntermediaryObject" name="NetNamedPipeBinding_IIntermediaryObject">
</endpoint>
</client>
<diagnostics>
<!-- Unrelated tracing info, removed for brevity -->
</diagnostics>
</system.serviceModel>
This answer帮助我为netNamedPipeBinding生成所需的客户端配置/代理类
