WCF over net.tcp 与安全模式 none 给出异常

【中文标题】WCF over net.tcp 与安全模式 none 给出异常【英文标题】：WCF over net.tcp with security mode none gives exception 【发布时间】：2013-05-02 23:18:23 【问题描述】：我们通过 WCF 使用回调来流式传输数据。 WCF 托管在 IIS 中（默认设置，只是将 net.tcp 添加到协议中）。
我们正在尝试禁用 WCF 上的安全性，因此我在客户端和服务器上都将安全模式设置为“无”，但我收到以下 CommunicationException：
套接字连接被中止。这可能是由错误引起的 处理您的消息或接收超时被超过 远程主机或底层网络资源问题。本地插座 超时为“00:00:59.8439844”。
我已经对服务进行了跟踪，并且 TraceViewer 给了我以下异常 (System.ServiceModel.ProtocolException)：
需要流安全性 http://www.w3.org/2005/08/addressing/anonymous，但没有安全性 上下文进行了协商。这可能是由远程端点引起的 从其绑定中缺少 StreamSecurityBindingElement。
Client Program.cs：
using System;
using System.ServiceModel;
using WcfClient.ServiceReference1;
class Program
static void Main()
Callback callback = new Callback();
InstanceContext context = new InstanceContext(callback);
Service1Client service1Client = new Service1Client(context,
"NetTcpBinding_IService1");
service1Client.GetData(0);
Console.Read();
service1Client.Stop();
internal class Callback : IService1Callback
public void StreamSignalData(int[] result)
foreach (int i in result)
Console.WriteLine(DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss.fff") +
": " + i);

任何想法这可能是什么？ 谷歌上的大多数点击都说客户端和服务器上的配置应该是相同的（即没有安全性），但我似乎找不到错误。 谷歌搜索 StreamSecurityBindingElement 没有找到好的解释...
【问题讨论】：
哪一方（客户端/服务）在您的日志中为您提供错误？ @PetarVučetin 服务。 @PetarVučetin 我尝试在客户端上进行跟踪，但除了已经抛出的异常之外，它没有给我任何其他信息。 【参考方案1】：我无法复制您的问题，但我有相同的设置和我注意到的几件事：
在您的 WCF Service1.svc.cs 中创建命名空间。
namespace WcfService1
[ServiceContract(SessionMode = SessionMode.Required,
CallbackContract = typeof (IStreamCallback),
ProtectionLevel = ProtectionLevel.None)]
public interface IService1
.....
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
[CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
public
class Service1 : IService1
<service name="Service"> 应该是 <service name="WcfService1.Service1">。服务名称是服务的完整类型。
配置中的服务部分：
<services>
<service name="WcfService1.Service1">
<endpoint address="" binding="wsDualHttpBinding"
bindingConfiguration="wsDualHttpBinding"
name="EndPointHTTP" contract="WcfService1.IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" name="mex"
contract="IMetadataExchange" />
<endpoint binding="netTcpBinding" bindingConfiguration="netTcpBinding"
name="EndPointTCP" contract="WcfService1.IService1" />
</service>
</services>
WCF Service1.svc.cs
using System;
using System.Net.Security;
using System.ServiceModel;
using System.Threading;
namespace WcfService1
[ServiceContract(SessionMode = SessionMode.Required,
CallbackContract = typeof (IStreamCallback),
ProtectionLevel = ProtectionLevel.None)]
public interface IService1
[OperationContract]
void GetData(int value);
[OperationContract]
void Stop();
public interface IStreamCallback
[OperationContract(IsOneWay = true)]
void StreamSignalData(int[] result);
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
[CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
public class Service1 : IService1
private Timer _timer;
private readonly IStreamCallback _callback =
OperationContext.Current.GetCallbackChannel<IStreamCallback>();
public void GetData(int value)
_timer = new Timer(StreamData, null, 0, 500);
public void Stop()
_timer.Dispose();
private void StreamData(object state)
int[] randomNumbers = new int[50];
Random random = new Random();
for (int i = 0; i < 50; i++)
randomNumbers[i] = random.Next(100);
_callback.StreamSignalData(randomNumbers);
回调
确保您处理 _callback.StreamSignalData(randomNumbers);当客户端断开连接时。您将收到通信异常。

感谢您的意见，但不幸的是，这并没有解决我的问题 这很奇怪。好吧 - 我赢得了“它可以在我的电脑上运行”徽章：以上是关于WCF over net.tcp 与安全模式 none 给出异常的主要内容，如果未能解决你的问题，请参考以下文章
