无法将数据写入传输连接:已建立的连接被主机中的软件中止

本文关键字：连接 建立 主机 软件 数据 传输 | 更新日期: 2023-09-27 17:56:32

我正在编写一个与 WCF 服务配合使用的上载控件，当我尝试上传超过 1MB 的文件时，出现此错误：

{System.IO.IOException: Unable to write data to the transport connection: 
 An established connection was aborted by the software in your host machine. 
---> System.Net.Sockets.SocketException: An established connection was aborted by the 
     software in your host machine
at System.Net.Sockets.Socket.Send(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size)
--- End of inner exception stack trace ---
at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size)
at System.Net.PooledStream.Write(Byte[] buffer, Int32 offset, Int32 size)
at System.Net.ConnectStream.InternalWrite(Boolean async, Byte[] buffer, Int32 offset, Int32 size, AsyncCallback callback, Object state)
at System.Net.ConnectStream.Write(Byte[] buffer, Int32 offset, Int32 size)}

我不知道这是否与 json 最大长度参数有关。我知道在 Web 应用程序中我可以将其添加到 web.config 文件中

<system.web.extensions>
<scripting>
  <webServices>
    <jsonSerialization maxJsonLength="50000000"/>
  </webServices>
</scripting>

但是我是WCF的新手，不知道如何在这里处理它......

您可能

正在超时。首先，打开绑定中的保持连接。其次，检查请求和回复的时间戳。如果发送方和接收方之间存在防火墙，请确保它不会因为空闲超时而关闭连接。

我解决了。

  1. 删除[WebInvoke...]，仅保留界面中的[OperationContract]
  2. 使用这些配置文件

客户端配置：

<system.web>
    <compilation debug="true" targetFramework="4.0" />
    <httpRuntime maxRequestLength="2147483647" />
