Question

我一直在努力解决这个问题，并且可以真正使用一些帮助。

我正在尝试设计一个WCF端点，允许将图像流式传输到服务器，然后返回imageURL（即：“http://images.site.com/someimage.jpg”）。

目前，对我的WCF方法的调用如下所示：

for (var i = 0; i <= (Request.Files.Count - 1); i++)
{
client = new SOAPFileTransferServiceClient();
fileinfo = new FileTransferInfo();
m_objFile = Request.Files[i];

if (!(m_objFile == null | string.IsNullOrEmpty(m_objFile.FileName) |  _objFile.ContentLength < 1))
   {

   fileinfo.FileSize = m_objFile.ContentLength;
   fileinfo.FileName = Path.GetFileName(m_objFile.FileName);
   fileinfo.UserID = Context.Request["sid"].ToString();

   client.UploadFile(fileinfo, m_objFile.InputStream);

   if (retParam.param2 == 0)
   imgurl.Add(retParam.param1);

  }

}

我正在努力解决的错误是：

传输模式流式传输不是支持 ReliableSessionBindingElement。

到目前为止，我已尝试使用创建自定义netTcp绑定在消息编码元素之前添加。我也改变了我的transerMode属性到streamedRequest（感谢marc_s的建议）允许请求流式传输而不是响应。这似乎可以做到这一点，但我仍然得到相同的错误（这次“传输模式StreamedRequest不是......”）。

我没有想法。

以下是文件传输服务合同。除了SOAP端点之外，我还有JSON和POX。我还有两个MEX端点（一个用于mexHttp，另一个用于netTcp）。最后，我有http（对于json和pox）和netTcp（对于soap）基地址。

有什么不对劲吗？

<service behaviorConfiguration="transferServiceBehavior" name="MyProject.API.FileTransfer.FileTransferService">
            <endpoint address="json" behaviorConfiguration="WebHttpEPBehavior"
              binding="webHttpBinding" bindingConfiguration="jsonWeb" name="MyJSONFileTransferEP"
              contract="MyProject.API.FileTransfer.IJSONFileTransferService" />
            <endpoint address="pox" behaviorConfiguration="WebHttpEPBehavior"
              binding="webHttpBinding" bindingConfiguration="poxWeb" name="MyPOXFileTransferEP"
              contract="MyProject.API.FileTransfer.IPOXFileTransferService" />
            <endpoint address="httpMex" binding="mexHttpBinding" bindingConfiguration=""
              contract="IMetadataExchange" />
            <endpoint address="soap" behaviorConfiguration="NetTcpEPBehavior"
              binding="customBinding" bindingConfiguration="netTcpCustom"
              name="MySOAPFileTransferEP" contract="MyProject.API.FileTransfer.ISOAPFileTransferService" />
            <endpoint address="nettcpMex" binding="netTcpBinding" bindingConfiguration=""
              contract="IMetadataExchange" />
            <host>
              <baseAddresses>
                <add baseAddress="http://localhost:2544/filetransfer/" />
                <add baseAddress="net.tcp://localhost:2544/filetransfer/" />
              </baseAddresses>
            </host>
          </service>

这是我的服务合同使用的自定义绑定：

<customBinding>
    <binding name="netTcpCustom"
             closeTimeout="00:01:00"
             openTimeout="00:01:00"
             receiveTimeout="00:10:00"
             sendTimeout="00:01:00">
      <reliableSession />
      <compositeDuplex />
      <oneWay />
      <windowsStreamSecurity protectionLevel="None" />
      <mtomMessageEncoding  />
      <tcpTransport maxBufferPoolSize="524288"
                    maxReceivedMessageSize="2147483647"
                    connectionBufferSize="8192"
                    hostNameComparisonMode="StrongWildcard"
                    channelInitializationTimeout="00:01:00"
                    maxBufferSize="2147483647"
                    maxPendingConnections="20"
                    maxOutputDelay="00:00:00.2000000"
                    maxPendingAccepts="5"
                    transferMode="StreamedRequest"
                    listenBacklog="20"
                    portSharingEnabled="false"
                    teredoEnabled="false">
        <connectionPoolSettings groupName="default" leaseTimeout="00:05:00"
            idleTimeout="00:02:00" maxOutboundConnectionsPerEndpoint="20" />
      </tcpTransport>
    </binding>
  </customBinding>

任何和所有建议都非常感谢。谢谢你的帮助。

Answer 1

那么，如果丢弃可靠的会话元素，StreamedRequest方法是否有效？你能活下去吗？如果您使用的是netTcp，那么您可能会支持企业防火墙，对吗？所以你可能会在没有可靠的会话开销的情况下离开......

此外 - WCF有很多选项和可能的功能组合 - 并非一切都有意义，并不是所有东西都能协同工作 - 也许这只是WCF的一个限制，而不是你的配置问题。

你的配置唯一奇怪的是你的netTcp自定义绑定中的mtomMessageEncoding - 为什么不使用更有效的二进制编码？

<binding name="netTcpCustom"
         closeTimeout="00:01:00"
         openTimeout="00:01:00"
         receiveTimeout="00:10:00"
         sendTimeout="00:01:00">
  <reliableSession />
  <compositeDuplex />
  <oneWay />
  <windowsStreamSecurity protectionLevel="None" />
  <mtomMessageEncoding  />
  <tcpTransport maxBufferPoolSize="524288"

为什么不使用

  <binaryMessageEncoding />

代替??
