[WCF][SyncFramework] 如何覆盖 GetWebRequest？

Question

我有一个由 Sync Framework 生成的 WCF 客户端/服务器架构。 由于某种原因，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）

敲了敲键盘后，我发现我必须重写 GetWebRequest 才能更改我想要的有关 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。如果我能做到这一点，似乎错过了足够的课程。互联网上有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：

    public string[] TestConnect(SyncGroupMetadata groupMetadata, SyncSession syncSession)
    {
        return base.Channel.TestConnect(groupMetadata, syncSession);
    }
} 

如果有人找到答案，我将永远感激那个人。

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 不喜欢由 transferMode=Streamed 引起的分块消息。

但是等等！还有更多！

现在仍然存在一个潜在问题，因为同步率达到了 ~14%：

（翻译错误）错误的 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。在另一个网络上没问题。

我正在解决这个问题，但如果你有想法，你就会成为我的英雄。
