基础连接已经关闭：连接被意外关闭 [英] The underlying connection was closed: The connection was closed unexpectedly

问题描述

此异常始终抛出一个SOAP请求这需要将近三分钟，接收和2.25兆大小。

在网上淘我发现各种各样的职位，所有似乎是关于请求设置标题，有的要我不发送期待：头，有的要我发送保持活动头部，但头部的irregardless我送我仍然得到这个讨厌的错误。我不相信设置任何头就是我的回答，因为我可以使用卷曲重新创建完全相同的请求和响应最终会回来没有问题，什么那么以往的。

我的＆LT;的httpRuntime maxRequestLength的=409600executionTimeout =900/＆GT; 。

我觉得如果我跑出来的选择。如果任何人都可以提供任何帮助，我将不胜感激。一些其他的事情要注意的是，该服务器，我请求数据是从我手中，还这些请求是通过https和更小的响应其他请求工作得很好。

感谢

解决方案

您标记出任.NET35，让您使用WCF

？

如果是这样，这里是App.config中，我们使用大数据集的一个例子：

 ＆LT; system.serviceModel＆GT;
    ＆LT;绑定＆GT;
      ＆LT; basicHttpBinding的＆GT;
        ＆LT;绑定名称=basicHttpBinding的maxBufferSize =2147483647maxReceivedMessageSize =2147483647＆GT;
          ＆LT; readerQuotas MAXDEPTH =32maxStringContentLength =8388608maxArrayLength =16384maxBytesPerRead =4096maxNameTableCharCount =16384/＆GT;
        ＆LT; /装订＆GT;
      ＆LT; / basicHttpBinding的＆GT;
    ＆LT; /绑定＆GT;
    ＆LT;客户端＆GT;
      ＆LT;端点地址=HTTP：//本地主机：1602 / EndPoint.svc绑定=basicHttpBinding的bindingConfiguration =basicHttpBinding的合同=IEndPointContractNAME =端点behaviorConfiguration =EndpointBehaviour/＆GT;
    ＆LT; /客户＆GT;
    ＆LT;行为＆GT;
      ＆LT; endpointBehaviors＆GT;
        ＆LT;行为NAME =EndpointBehaviour＆GT;
          ＆LT; D​​ataContractSerializer的maxItemsInObjectGraph =2147483647/＆GT;
        ＆LT; /行为＆GT;
      ＆LT; / endpointBehaviors＆GT;
    ＆LT; /行为＆GT;
  ＆LT; /system.serviceModel>
 

This exception is consistently thrown on a SOAP Request which takes almost three minutes to receive and is 2.25 megs in size.

When scouring the web I find all sorts of posts which all seem to be about setting headers on the Request, some want me to not send the "Expect:" header, some want me to send the "Keep-Alive:" header, but irregardless of the headers I send I still get this pesky error. I don't believe that setting any headers is my answer, because I can recreate the exact same request using "curl" and a response does eventually come back with no problems what-so-ever.

My <httpRuntime maxRequestLength="409600" executionTimeout="900"/>.

I feel as if I'm running out of options. If anyone can provide any assistance I would be most grateful. A few other things to note would be that the server I'm Requesting data from is out of my hands, also these requests are over https and other requests with smaller responses work flawlessly.

Thanks

You tagged the post as .NET35, so are you using WCF?

If so, here is an example of the App.config we use for large data sets:

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="32" maxStringContentLength="8388608" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:1602/EndPoint.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding" contract="IEndPointContract" name="EndPoint" behaviorConfiguration="EndpointBehaviour" />     
    </client>
    <behaviors>
      <endpointBehaviors>
        <behavior name="EndpointBehaviour">
          <dataContractSerializer maxItemsInObjectGraph="2147483647" />
        </behavior>
      </endpointBehaviors>
    </behaviors>
  </system.serviceModel>
