我遇到[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
的问题我有简单的wcf服务,它托管在IIS 7中。
服务代码:
[ServiceContract(SessionMode = SessionMode.Allowed)]
public interface IService1
{
[OperationContract]
int SetMyValue(int val);
[OperationContract]
int GetMyValue();
}
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession )]
public class Service1 : IService1
{
int MyValue = 0;
public int SetMyValue(int val)
{
MyValue = val;
return MyValue;
}
public int GetMyValue()
{
return MyValue;
}
}
如果服务站点使用http,则一切正常。 例如,[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]客户端的结果是:
Service1Client客户端=新Service1Client();
client.GetMyValue(); // ==>返回0
client.SetMyValue(1); // ==>返回1
client.GetMyValue(); // ==>返回1
client.SetMyValue(6); // ==>返回6
client.GetMyValue(); // ==>返回6
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]结果是:
Service1Client客户端=新Service1Client();
client.GetMyValue(); // ==>返回0
client.SetMyValue(1); // ==>返回1
client.GetMyValue(); // ==>返回0
client.SetMyValue(6); // ==>返回6
client.GetMyValue(); // ==>返回0
现在,当我将服务配置为使用https并使用证书传输安全性InstanceContextMode.PerSession就像InstanceContextMode.PerCall一样。
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]客户端的结果现已更改:
Service1Client客户端=新Service1Client();
client.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser,StoreName.My,X509FindType.FindByThumbprint,“3d6ca7a6ebb8a8977c958a3d8e4436337b273e4e”);
client.GetMyValue(); // ==>返回0
client.SetMyValue(1); // ==>返回1
client.GetMyValue(); // ==>返回0
client.SetMyValue(6); // ==>返回6
client.GetMyValue(); // ==>返回0
我的服务web.config是:
<bindings>
<wsHttpBinding>
<binding name="wsHttpEndpointBinding">
<security mode="Transport">
<transport clientCredentialType="Certificate"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="ServiceBehavior" name="WcfServiceLibrary1.Service1">
<endpoint address="" binding="wsHttpBinding" bindingConfiguration="wsHttpEndpointBinding"
name="wsHttpEndpoint" contract="WcfServiceLibrary1.IService1" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpsGetEnabled="true" httpGetEnabled="false"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
为什么PerSession就像PerCall一样?我错误配置了什么?
答案 0 :(得分:2)
我通过HTTPS获得了会话支持。
WSHttpBinding不支持基于传输安全性(HTTPS)的可靠会话。
我没有使用wsHttpBinding,而是创建了一个自定义绑定:
<customBinding>
<binding configurationName="customReliableHttpBinding">
<reliableSession />
<textMessageEncoding/>
<httpsTransport authenticationScheme="Anonymous" requireClientCertificate="true"/>
</binding>
</customBinding>
