将流上传到 WCF IIS 7 托管服务无法正常工作

我有一个 wcf 服务，我正在将其设置为在 IIS 7 下运行。我已将该服务设置为传输模式的流式传输。当我在控制台应用程序中自行托管服务时，一切似乎都工作正常。但是，当客户端连接到 iis 托管服务时，它似乎正在缓冲，并且客户端最终会超时。我已经使用 fiddler 来确定客户端超时发生在 http 请求发出之前。

这是服务器绑定。

var binding = new CustomBinding();
            binding.Elements.Add( new TextMessageEncodingBindingElement()
            {
                MessageVersion = MessageVersion.Soap12WSAddressing10
            } );

            var secBinding = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
            secBinding.AllowInsecureTransport = true;
            binding.Elements.Add( secBinding );
            binding.Elements.Add( new HttpTransportBindingElement()
            {
                TransferMode = TransferMode.Streamed,
                MaxReceivedMessageSize = Int32.MaxValue,

            } );

客户端绑定：

var binding = new CustomBinding();
            binding.Elements.Add( new TextMessageEncodingBindingElement()
            {
                MessageVersion = MessageVersion.Soap12WSAddressing10
            } );

            var secBinding = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
            secBinding.AllowInsecureTransport = true;
            binding.Elements.Add( secBinding );
            binding.Elements.Add( new HttpTransportBindingElement()
            {
                TransferMode = TransferMode.Streamed,
                MaxReceivedMessageSize = Int32.MaxValue,
                MaxBufferSize = 400
            } );

顺便说一句，连接超时，因为流是无限的，服务器应该读取前几个字节，然后关闭流。

原文

I have a wcf service I am setting up to run under IIS 7. I have the service set to streaming for the transfermode.
When I self host the service in a console application every thing seems to work ok. But when the client connects to an iis hosted service it seems to be buffering, and the client eventual times out. I have used fiddler to determine that this client time out happens before the http request is even made.

Here is the servers binding.

var binding = new CustomBinding();
            binding.Elements.Add( new TextMessageEncodingBindingElement()
            {
                MessageVersion = MessageVersion.Soap12WSAddressing10
            } );

            var secBinding = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
            secBinding.AllowInsecureTransport = true;
            binding.Elements.Add( secBinding );
            binding.Elements.Add( new HttpTransportBindingElement()
            {
                TransferMode = TransferMode.Streamed,
                MaxReceivedMessageSize = Int32.MaxValue,

            } );

And the client binding:

var binding = new CustomBinding();
            binding.Elements.Add( new TextMessageEncodingBindingElement()
            {
                MessageVersion = MessageVersion.Soap12WSAddressing10
            } );

            var secBinding = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
            secBinding.AllowInsecureTransport = true;
            binding.Elements.Add( secBinding );
            binding.Elements.Add( new HttpTransportBindingElement()
            {
                TransferMode = TransferMode.Streamed,
                MaxReceivedMessageSize = Int32.MaxValue,
                MaxBufferSize = 400
            } );

As an aside the connection is timing out because the stream is infinite and the server should read the first few bytes and then close the stream.
