WCF wsHttpBinding 与 http keepalive

发布于 2024-11-17 18:58:45 字数 1386 浏览 4 评论 0原文

我有一个使用 wsHttpBinding 的 WCF 客户端，我想启用 http keep-alive。

我希望我可以通过更改客户端配置来打开此功能...我已经找到了大量有关如何打开 basicHttp 绑定的保持活动的描述，但 wsHttpBinding 没有运气...这可能吗？

非常感谢。

这是我的客户端绑定：

  <wsHttpBinding>
    <binding name="WSHttpBinding_IRepositoryService" closeTimeout="00:00:10"
      openTimeout="00:00:10" receiveTimeout="00:05:00" sendTimeout="00:05:00"
      bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
      maxBufferPoolSize="524288" maxReceivedMessageSize="655360" messageEncoding="Mtom"
      textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
      <readerQuotas maxDepth="32" maxStringContentLength="81920" maxArrayLength="163840"
        maxBytesPerRead="409600" maxNameTableCharCount="16384" />
      <reliableSession ordered="true" inactivityTimeout="00:10:00"
        enabled="true" />
      <security mode="Message">
        <transport clientCredentialType="Windows" proxyCredentialType="None"
          realm="">
          <extendedProtectionPolicy policyEnforcement="Never" />
        </transport>
        <message clientCredentialType="Windows" negotiateServiceCredential="true"
          algorithmSuite="Default" establishSecurityContext="true" />
      </security>

    </binding>
</wsHttpBinding>

I have a WCF client which uses a wsHttpBinding, I would like to enable http keep-alive.

I'm hoping I can turn this on by just changing the client config... I've found plenty of descriptions of how to turn on keep-alives for a basicHttp binding, but no luck with wsHttpBinding... is this possible?

Many thanks.

Here's my client binding:

  <wsHttpBinding>
    <binding name="WSHttpBinding_IRepositoryService" closeTimeout="00:00:10"
      openTimeout="00:00:10" receiveTimeout="00:05:00" sendTimeout="00:05:00"
      bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
      maxBufferPoolSize="524288" maxReceivedMessageSize="655360" messageEncoding="Mtom"
      textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
      <readerQuotas maxDepth="32" maxStringContentLength="81920" maxArrayLength="163840"
        maxBytesPerRead="409600" maxNameTableCharCount="16384" />
      <reliableSession ordered="true" inactivityTimeout="00:10:00"
        enabled="true" />
      <security mode="Message">
        <transport clientCredentialType="Windows" proxyCredentialType="None"
          realm="">
          <extendedProtectionPolicy policyEnforcement="Never" />
        </transport>
        <message clientCredentialType="Windows" negotiateServiceCredential="true"
          algorithmSuite="Default" establishSecurityContext="true" />
      </security>

    </binding>
</wsHttpBinding>

您必须使用自定义绑定才能禁用Keep-Alive 标头，因为该功能未在任何内置绑定类中公开。

无需从头开始定义自定义绑定即可实现此目的的最简单方法是自定义现有的 BasicHttpBinding 或 WSHttpBinding 实例关联到代码中的客户端代理。

这是一个例子：

var proxy = new MyServiceClient();
var customBinding = new CustomBinding(proxy.Endpoint.Binding);
var transportElement = customBinding.Elements.Find<HttpTransportBindingElement>();
transportElement.KeepAliveEnabled = false;

proxy.Endpoint.Binding = customBinding;

You'll have to use a custom binding in order to disable the Keep-Alive header, since that feature is not exposed in any of the built-in binding classes.

The easiest way to achieve this without having to define a custom binding from scratch, is to customize the existing BasicHttpBinding or WSHttpBinding instance associated to the client proxy in code.

Here's an example:

var proxy = new MyServiceClient();
var customBinding = new CustomBinding(proxy.Endpoint.Binding);
var transportElement = customBinding.Elements.Find<HttpTransportBindingElement>();
transportElement.KeepAliveEnabled = false;

proxy.Endpoint.Binding = customBinding;
