WCF System.TimeoutException : The socket transfer timed out after 00:00:00

Question

我正在使用 WAS 中托管的 wcf net tcp 服务和 Windows 身份验证。该服务始终因来自特定客户端计算机的特定用户凭据而失败。凭据在不同的客户端计算机上工作。不同的凭据在客户端计算机上工作。但是，使用特定的客户端计算机和凭据，该服务始终失败并出现以下错误:

System.TimeoutException: The open operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout. ---> System.TimeoutException: The socket transfer timed out after 00:00:00. You have exceeded the timeout set on your binding. The time allotted to this operation may have been a portion of a longer timeout. ---> System.IO.IOException: The write operation failed, see inner exception. ---> System.TimeoutException: The socket transfer timed out after 00:00:00. You have exceeded the timeout set on your binding. The time allotted to this operation may have been a portion of a longer timeout.

请注意，超时是在 00:00:00 之后，即使它配置为 00:01:00。这让我相信这实际上不是超时问题。这是我的绑定(bind):

          <netTcpBinding>
        <binding name="NetTcpBinding_IMyAwesomeService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxConnections="10" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" />
          <security mode="Transport">
            <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
            <!--<extendedProtectionPolicy policyEnforcement="Never" />-->
            <message clientCredentialType="Windows" />
          </security>
        </binding>
      </netTcpBinding>

我现在正在设置 E2E 跟踪，并会在我得到结果后发回。

您在异常中看到的超时值表示在超时之前还剩余多少操作时间。因此，上述内容肯定会出现超时问题。绑定(bind)中配置的超时时间很低，似乎需要超过 1 分钟。您可以尝试增加超时值，很可能是打开超时值。
