Question

我有一个由Sync Framework生成的WCF客户端/服务器架构。出于某种原因，我必须将客户端POST消息的HTTP版本从1.1更改为1.0（因为客户端和服务器之间的代理）

在敲击键盘后，我发现我必须覆盖GetWebRequest来改变我想要的关于HTTP协议的任何内容：

protected override WebRequest GetWebRequest(Uri uri)
{
    HttpWebRequest webRequest = (HttpWebRequest) base.GetWebRequest(uri);

    webRequest.KeepAlive = false;
    webRequest.ProtocolVersion=HttpVersion.Version10;
    return webRequest;
}

似乎我必须在生成的Reference.cs文件中执行此覆盖，但我不能。我能做到这一点似乎错过了足够的课程。互联网上的一些人遇到过这种问题，但从来没有这种架构和那种Reference.cs文件。

这是Reference.cs代码：

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(ConfigurationName = "VinciWCFRef.ISyncVinciSyncContract")]
public interface ISyncVinciSyncContract

    [System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults = true)]
    string[] TestConnect(SyncGroupMetadata groupMetadata, SyncSession syncSession);

    public string[] TestConnect(SyncGroupMetadata groupMetadata, SyncSession syncSession)
    {

    }
}

如果有人找到答案，那个人将会得到我永恒的感激之情。

app.config中的

transferMode = StreamedResponse 帮助我解决了这个问题。

<bindings>
      <basicHttpBinding>
        <binding name="basicHttpBinding" closeTimeout="00:45:00" openTimeout="00:45:00"
          receiveTimeout="00:45:00" sendTimeout="00:45:00" allowCookies="false"
          bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
          messageEncoding="Text" textEncoding="utf-8" transferMode="StreamedResponse"
          useDefaultWebProxy="true">
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode="None">
            <transport clientCredentialType="None" realm="" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

Squid代理3.1.20不喜欢 transferMode = Streamed 引起的分块消息。

但是等等！还有更多！

现在仍然存在潜在的问题，因为同步达到了~14％：

（严重翻译）糟糕的SOAP地址或操作。内部异常：404错误

此异常仅在通过squid代理时触发。在另一个网络上没关系。

我正在研究这个问题，但如果你有一个想法，那么你将成为我的英雄。
