Wcf procy api调用失败并出现错误 - 底层连接已关闭：接收时发生意外错误。 [英] Wcf procy api call fails with error - the underlying connection was closed: an unexpected error occurred on a receive.

问题描述

我在winXP sp3机器上自我托管WCF服务，客户端在同一台机器上。我试图调用服务api，它给了我以下错误

I am self hosting a WCF service on winXP sp3 machine and the client is on the same machine.I tried to call the service api and it gave me following error

An existing connection was forcibly closed by the remote host

Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
                                                                                 at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
                                                                                 at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size)
                                                                                 at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)
                                                                              
                                                                              The underlying connection was closed: An unexpected error occurred on a receive.
                                                                                
But same service when hosted on remote machine and client accessing service is on windows xpsp3 machine then it works.

Is there a known issue for winxpsp3 machine when both client and service are on same machine.

Thanks in advance

What I have tried:

I tried WCF tracing on client machine and I found following error

推荐答案

I hosted service using localhost in the endpoint URL and same for agent proxy.On Win XPSP3 I observed that by changing the machine name from "Localhost" to "127.0.0.1" the communication was working as expected.
But on winXPSP2 "localhost" works.
Not sure whether this is related to some security patch that is present in winXPSP3
