我有一个基于WCF的进程需要一些时间。如果需要帮助,WCF服务在Azure中运行。我认为问题与超时有关:
1)Winforms客户端在绑定部分具有以下.config设置:
我有一个基于WCF的进程需要一些时间。如果需要帮助,WCF服务在Azure中运行。我认为问题与超时有关:
1)Winforms客户端在绑定部分具有以下.config设置:
<wsHttpBinding>
<binding name="XXX" closeTimeout="00:05:00" openTimeout="00:05:00"
receiveTimeout="00:10:00" sendTimeout="00:10:00" bypassProxyOnLocal="false"
transactionFlow="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="10000000" maxReceivedMessageSize="10000000"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="255" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00"
enabled="false" />
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
<message clientCredentialType="UserName" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="false"/>
</security>
</binding>
</wsHttpBinding>
2)WCF服务在web.config中具有以下绑定部分
<wsHttpBinding>
<binding name="XXX" maxReceivedMessageSize="10000000" sendTimeout="00:10:00" receiveTimeout="00:10:00" closeTimeout="00:10:00" openTimeout="00:10:00">
<security mode="TransportWithMessageCredential">
<message clientCredentialType="UserName" establishSecurityContext="false" />
</security>
<readerQuotas maxArrayLength="2000000" maxBytesPerRead="10000000" maxStringContentLength="10000000" maxDepth="255" />
</binding>
</wsHttpBinding>
3) 我在WCF中有一个长时间运行的方法(通常需要2分钟)。客户端调用该方法,那些执行时间超过1分钟的客户端会抛出异常。这是最内部的异常:
<InnerException>
<Type>System.Net.Sockets.SocketException</Type>
<Message>An existing connection was forcibly closed by the remote host</Message>
<StackTrace>
<Frame>at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)</Frame>
</StackTrace>
</InnerException>
</InnerException>
4) WCF调用本身成功完成,但仍抛出异常(服务器端已记录开始和结束)。如何避免这种异常?
谢谢!
