我在让交通安全工作方面遇到问题。
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。没有任何安全保障，我也可以很好地沟通。但是当我使用以下设置打开传输安全性时：
- 安全模式=传输
- 传输 ClientCredentialType = Windows
- 保护级别 = 加密并签名
当服务A调用服务B时出现错误：
System.ServiceModel.CommunicationException：套接字连接已中止。这可能是由于处理消息时出错、远程主机超过接收超时或底层网络资源问题造成的。本地套接字超时为“00:00:09.7810000”。 ---> System.IO.IOException: 读取操作失败，请参阅内部异常。 ---> System.ServiceModel.CommunicationException：套接字连接已中止。这可能是由于处理消息时出错、远程主机超过接收超时或底层网络资源问题造成的。本地套接字超时为“00:00:09.7810000”。 ---> System.Net.Sockets.SocketException：现有连接被远程主机强制关闭
我尝试将接收和发送超时更改为 5 分钟，但在大致相同的超时持续时间下仍然出现相同的错误。唯一的区别是我需要等待 5 分钟而不是 1 分钟。
任何人都可以深入了解原因是什么以及如何解决这个问题吗？
附件是这两个服务的配置文件：

有一个解决方案here http://www.codeproject.com/Questions/633699/Socket-Exception-WCF...你应该试试...
-
在服务和客户端配置中添加了这些行为。
<behaviors>
<endpointBehaviors>
<behavior name="endpointBehavior">
<dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>
</endpointBehaviors>
</behaviors>
-
将客户端和服务器配置中的这些值更新为最大大小。
<binding name="tcpBinding" receiveTimeout="00:15:00" sendTimeout="00:15:00" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647">
<security mode="None">
<transport clientCredentialType="None" protectionLevel="None" />
<message clientCredentialType="None" />
</security>
</binding>
希望能帮助到你。
