wcf - 更改 WCF 默认超时

Question

我这里有一个 WCF 双工服务，要求是对客户端的回调应该有 10 秒的超时，因此我的服务的 web.config 文件如下所示:

        <bindings>
        <basicHttpBinding>
            <binding name="simulatorEndpoint" closeTimeout="00:00:10" openTimeout="00:00:10" 
                receiveTimeout="00:00:10" sendTimeout="00:00:10" allowCookies="false"
                bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                useDefaultWebProxy="true">

                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <security mode="None">
                    <transport clientCredentialType="None" proxyCredentialType="None"
                        realm="" />
                    <message clientCredentialType="UserName" algorithmSuite="Default" />
                </security>
            </binding>
        </basicHttpBinding>
        <wsDualHttpBinding>
            <binding name="wsdualEndpoint" closeTimeout="00:00:10" openTimeout="00:00:10"
                receiveTimeout="00:00:10" sendTimeout="00:00:10" bypassProxyOnLocal="false"
                transactionFlow="false" hostNameComparisonMode="StrongWildcard"
                maxBufferPoolSize="524288" maxReceivedMessageSize="65536" clientBaseAddress="http://localhost:1235"
                messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <reliableSession ordered="true" inactivityTimeout="00:00:10"  />
                <security mode="Message">
                    <message clientCredentialType="Windows" negotiateServiceCredential="true"
                        algorithmSuite="Default" />
                </security>
            </binding>
        </wsDualHttpBinding>
    </bindings>

在客户端，app.config 文件中的绑定(bind)具有相同的超时值。

现在的效果是，如果客户端向服务器发送请求，则超时为 10 秒。但另一方面，如果服务向客户端发送回调，则超时为 1 分钟。这很奇怪......显然超时是在客户端正确设置的......但不是在服务上......我怎样才能更改服务的超时？

PS:我正在使用 Visual Studio 2010 及其 Debug模式和适当的 ASP.NET 开发服务器 10.0.0.0

binding timeouts的简要总结...

Client side:

• SendTimeout is used to initialize the OperationTimeout, which governs the whole interaction for sending a message (including receiving a reply message in a request-reply case). This timeout also applies when sending reply messages from a CallbackContract method.
• OpenTimeout and CloseTimeout are used when opening and closing channels (when no explicit timeout value is passed).
• ReceiveTimeout is not used.

Server side:

• Send, Open, and Close Timeout same as on client (for Callbacks).
• ReceiveTimeout is used by ServiceFramework layer to initialize the session-idle timeout.

也尝试将此添加到您的服务配置中

<behaviors>
   <endpointBehaviors>
      <behavior name="MyCallbackBehavior">       
         <callbackTimeouts transactionTimeout="00:00:10"/>
      </behavior>
   </endpointBehaviors>
<behaviors>

然后将行为添加到您的端点

<endpoint behaviorConfiguration="MyCallbackBehavior" />
