WCF serviceThrottling不起作用

Question

我有一個WCF服務，我已經配置使用serviceThrottling，但是這似乎並沒有工作。

我有一個MULT線程客戶端調用該服務@

http://localhost:7778/test/sleep?sleep=1000 

和服務器似乎忽略最大??? WCF配置中的設置。

我真的想要做的是增加concurent連接的數量，但它似乎並沒有影響設置。

我的服務器託管如下：

  WebServiceHost zHost = new WebServiceHost(typeof (Service1)); 

      zHost.Open(); 
      Console.WriteLine("Started"); 
      Console.ReadLine(); 
      zHost.Close(); 

在app.config設置如下：

<?xml version="1.0" encoding="utf-8" ?> 
    <configuration> 
     <startup> 
      <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> 
     </startup> 
     <system.net> 
     <connectionManagement> 
      <add address="*" maxconnection="65535"/> 
     </connectionManagement> 
     </system.net> 
     <system.serviceModel> 
     <standardEndpoints /> 
     <behaviors> 
      <endpointBehaviors> 
      <behavior name="NewBehavior0"> 
       <webHttp /> 
      </behavior> 
      </endpointBehaviors> 
      <serviceBehaviors> 
      <behavior name="NewBehavior0"> 
       <serviceThrottling maxConcurrentCalls="1" maxConcurrentSessions="1" maxConcurrentInstances="1" /> 
      </behavior> 
      </serviceBehaviors> 
     </behaviors> 
     <services> 
      <service name="WCF_REST_TEST_1.Service1"> 
      <endpoint address="/test" behaviorConfiguration="NewBehavior0" binding="webHttpBinding" bindingConfiguration="" contract="WCF_REST_TEST_1.IService1" /> 
      <host> 
       <baseAddresses> 
       <add baseAddress="http://localhost:7778" /> 
       </baseAddresses> 
      </host> 
      </service> 
     </services> 
     </system.serviceModel> 
    </configuration> 

如果服務1的設置如下：

[ServiceContract] 
public interface IService1 
{ 

    [WebGet(UriTemplate = "sleep?sleep={value}", ResponseFormat = WebMessageFormat.Json)] 
    [OperationContract] 
    CompositeType sleep(int value); 
} 

和

public class Service1 : IService1 
{ 

    public CompositeType sleep(int sleep) 
    { 
     Stopwatch sw = new Stopwatch(); 
     sw.Start(); 
     if (sleep > 0) 
     { 
      try 
      { 
       logger.Log(LogLevel.Info, "Sleep Request recieved: {0}ms", sleep); 
       Thread.Sleep(sleep);     
      } 
      catch (Exception ex) 
      { 
       logger.Log(LogLevel.Error, "Error. {0} - {1}", ex.Message, ex.InnerException); 
      } 
     } 
     else 
     { 
      logger.Log(LogLevel.Info, "No Sleep value supplied"); 
     } 

     sw.Stop(); 
     CompositeType zTest = new CompositeType(); 
     zTest.BoolValue = true; 
     zTest.StringValue = "Some String 2" + sleep; 
     //zTest.RemoteResponse = responseFromServer; 
     zTest.RemoteTime = sw.ElapsedMilliseconds; 

     return zTest; 
    } 
}

默認InstanceContextMode爲PerCall，所以你必須設置maxConcurrentCalls和maxConcurrentInstances

看起來像你，因爲只有一個呼叫支持

​​

例如

<system.serviceModel> 
    <services> 
     <service behaviorConfiguration="ServiceProviderBehavior" 
       name="ServiceProvider"> 
      <endpoint address="http://localhost:5060/" binding="webHttpBinding" 
         behaviorConfiguration="Web" contract="ServiceContracts.IService" /> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors> 
      <behavior name="ServiceProviderBehavior"> 
       <serviceMetadata httpGetEnabled="true" /> 
       <serviceThrottling maxConcurrentCalls="250" maxConcurrentInstances="250" /> 
      </behavior> 
     </serviceBehaviors> 
     <endpointBehaviors> 
      <behavior name="Web"> 
       <webHttp /> 
      </behavior> 
     </endpointBehaviors> 
    </behaviors> 
</system.serviceModel>
