将文件发送到 WCF 服务，套接字连接中止

Question

我有一个 WCF 服务（服务器），其方法的签名是

public void SetProfilePic(String pSession, Applicant pApplicant)

申请人有属性:

public byte[] Photo { get; set; }

我从客户端获取图像并调用 SetProfilePic。当图像较小时，大约 1cm X 1cm，效果很好，但是当图像较大时，大约 4cm X 3cm，出现以下错误

"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 '01:49:59.9779945'."

我已经增加了 app.config 文件中的 最大限制 ，但是我仍然遇到同样的错误。我在 buffered 模式下使用 NetTCPBinding。我也尝试过 MTOM。客户端和服务目前运行在同一台机器上，因为该项目仍处于初始开发阶段。

我在服务器端和客户端都启用了消息记录和跟踪，但是日志中没有提供更多详细信息，这不是很有帮助。

请在下面找到客户端和服务器的 App.config 文件。

我使用 WCF 的经验只有几个月。任何帮助表示赞赏。提前致谢。

Answer 1

服务器端的服务配置应该类似于

<endpoint address="net.tcp://localhost:9000/RecruitAidService"
    binding="netTcpBinding" bindingConfiguration="NetTcpBinding"
    name="NetTcpBinding" behaviorConfiguration="endpointBehavior"
    contract="RecruitAidServer.IRecruitAidService" />

和绑定

<bindings>
  <netTcpBinding>
    <binding name="NetTcpBinding" closeTimeout="01:50:00" openTimeout="01:50:00"
      receiveTimeout="01:50:00" sendTimeout="01:50:00" maxBufferPoolSize="21474836470000"
      maxBufferSize="2147483647" maxReceivedMessageSize="21474836470000"
      transferMode="Buffered" messageEncoding="Mtom">
      <readerQuotas maxDepth="128" maxStringContentLength="2147483647"
        maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="16384" />
    </binding>
  </netTcpBinding>
</bindings>
