Golang TCP错误wsarecv

Question

我正在编写一个监听的应用程序tcp connection(参见此示例).当tcp connection 断开连接时我收到错误read tcp ip_server.:port1->ip_client:port2: wsarecv: An existing connection was forcibly closed by the remote host. 我预期错误EOF和超时(for conn.SetReadDeadline())并试图捕获此代码的错误:

if err != nil {     
    log.Println("getting error from listener")
    // I thought, listener can continue work another cases
    if neterr, ok := err.(net.Error); ok && neterr.Timeout() || err == io.EOF {
        log.Println("Closing connection...")
        break // connection will be closed 
    }
}

有谁知道这个错误？你知道如何捕获此错误以及何时发生此错误？提前致谢 !

Answer 1

此错误的常见原因是您通过已由对等方关闭的连接发送数据.换句话说,应用程序协议错误.
