物流: 1臺運行WCF服務的服務器。 1臺運行WCF服務數據庫的服務器。WCF服務未假冒客戶端
問題: 我有一個WCF服務運行在1臺服務器上,它連接到一臺單獨的服務器以獲取它需要檢索的必要數據。我的問題是,當從客戶端機器調用服務時,我得到一個數據庫sql錯誤,指出'用戶登錄失敗'NT AUTHORITY \ ANONYMOUS LOGON'。我相信我已經設置了WCF服務來使用模擬。
WCF服務器配置:
<bindings>
<ws2007HttpBinding>
<binding maxReceivedMessageSize="214748">
<security mode="Message">
<transport clientCredentialType="Windows"
proxyCredentialType="Windows" realm="" />
<message clientCredentialType="Windows" negotiateServiceCredential="true"
algorithmSuite="Default" establishSecurityContext="true" />
</security>
</binding>
</ws2007HttpBinding>
</bindings>
<services>
<service behaviorConfiguration="Host.ServiceBehavior" name="Wcf.MyWebService">
<endpoint address="" behaviorConfiguration=""
binding="ws2007HttpBinding" contract="Wcf.MyWebServiceSoap">
<identity>
<servicePrincipalName value="ServerMachineName" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="Host.ServiceBehavior">
<serviceMetadata httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
<serviceAuthorization impersonateCallerForAllOperations="true" />
</behavior>
</serviceBehaviors>
</behaviors>
WCF服務代碼:
public class MySebService: MyWebServiceSoap
{
[OperationBehavior(Impersonation = ImpersonationOption.Required)]
public string TestWebMethod()
{
DbDal dal = CreateDataAccessLayer();
return dal.GetStringFromDatabase();
}
}
客戶端配置和代碼:
我編程設置如下配置:
public void TestWebMethod()
{
WS2007HttpBinding binding = new WS2007HttpBinding();
EndpointAddress endpoint = new EndpointAddress("uri");
ServiceClient client = new ServiceClient(binding, endpoint);
client.ClientCredentials.Windows.AllowedImpersonationLevel =
TokenImpersonationLevel.Impersonation;
client.ClientCredentials.Windows.AllowNtlm = true;
string result = client.TestWebMethod();
client.Close();
}
我以爲我曾嘗試將其更改爲委派,並沒有奏效。但我會再次投入一次。服務和客戶端的配置項目是否正確? – arc1880 2010-12-07 05:35:02
