WCF 传输安全:套接字连接已中止 [英] WCF transport security: socket connection was aborted
问题描述
我在确保运输安全方面遇到问题.
I have a problem in getting transport security to work.
我有 2 个服务(A 和 B)在同一台服务器上运行.服务 A 将调用服务 B 来执行某些任务.没有任何安全措施，我可以正常交流.但是当我使用以下设置打开传输安全性时:
I have 2 services (A & B) running in the same server. service A will call service B to perform some task. Without any security, I can communicate just fine. But when I turn on transport security with the following settings:
- 安全模式 = 传输
- TransportClientCredentialType = Windows
- ProtectionLevel = EncryptAndSign
服务 A 调用服务 B 时出错:
I got error when service A calls service B:
System.ServiceModel.CommunicationException:套接字连接已中止.这可能是由于处理您的消息时出错或远程主机超过接收超时，或底层网络资源问题引起的.本地套接字超时为00:00:09.7810000".---> System.IO.IOException: 读取操作失败，查看内部异常.---> System.ServiceModel.CommunicationException: 套接字连接已中止.这可能是由于处理您的消息时出错或远程主机超过接收超时，或底层网络资源问题引起的.本地套接字超时为00:00:09.7810000".---> System.Net.Sockets.SocketException: 一个现有的连接被远程主机强行关闭
System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:09.7810000'. ---> System.IO.IOException: The read operation failed, see inner exception. ---> System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:09.7810000'. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
我尝试将接收和发送超时更改为 5 分钟，但我仍然遇到相同的错误，超时持续时间大致相同.唯一的区别是我需要等待 5 分钟而不是 1 分钟.
I tried changing the receive and send timeout to 5 mins but I still get the same error with roughly the same timeout duration. The only difference is I need to wait out the 5 minutes instead of 1 minute.
谁能提供有关原因以及如何解决此问题的见解?
Can anyone provide an insight to what's the cause and how to resolve this?
附上两个服务的配置文件:

推荐答案
我为此创建了扩展方法.一种用于 NetTcpBinding，一种用于 NetNamedPipeBinding.当然只能用于内部服务.时间也是如此，当夜间未使用默认服务时，它会在早上第一次调用时失败.
I've created extension method for this. One for NetTcpBinding and one for NetNamedPipeBinding. Only to be used on internal services of course. Timings too as when a default service is not used during the night it will fail on the first call in the morning.
public static void ActivateMaxValues(this NetTcpBinding b)
{
b.OpenTimeout = TimeSpan.FromHours(10);
b.CloseTimeout = TimeSpan.FromMinutes(10);
b.ReceiveTimeout = TimeSpan.FromHours(10);
b.SendTimeout = TimeSpan.FromHours(10);
b.MaxBufferSize = int.MaxValue;
b.MaxReceivedMessageSize = int.MaxValue;
b.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas()
{
MaxArrayLength = int.MaxValue,
MaxBytesPerRead = int.MaxValue,
MaxDepth = int.MaxValue,
MaxNameTableCharCount = int.MaxValue,
MaxStringContentLength = int.MaxValue
};
}
public static void ActivateMaxValues(this NetNamedPipeBinding b)
{
b.TransactionFlow = true;
b.OpenTimeout = TimeSpan.FromHours(1);
b.CloseTimeout = TimeSpan.FromMinutes(10);
b.ReceiveTimeout = TimeSpan.FromHours(1);
b.SendTimeout = TimeSpan.FromHours(1);
b.MaxBufferSize = int.MaxValue;
b.MaxReceivedMessageSize = int.MaxValue;
b.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas()
{
MaxArrayLength = int.MaxValue,
MaxBytesPerRead = int.MaxValue,
MaxDepth = int.MaxValue,
MaxNameTableCharCount = int.MaxValue,
MaxStringContentLength = int.MaxValue
};
}
