英文:
Golang TCP error wsarecv
问题
我正在编写一个应用程序，它监听 tcp 连接（参见这个示例）。当一个 tcp 连接 断开时，我得到了错误信息 read tcp ip_server.:port1->ip_client:port2: wsarecv: 远程主机强制关闭了一个现有的连接。
我预期会出现错误 EOF 和超时（对于 conn.SetReadDeadline()），并尝试使用以下代码捕获错误：
if err != nil {
log.Println("从监听器获取错误")
// 我认为，监听器可以继续处理其他情况
if neterr, ok := err.(net.Error); ok && neterr.Timeout() || err == io.EOF {
log.Println("关闭连接...")
break // 连接将被关闭
}
}
有人了解这个错误吗？你知道如何捕获这个错误以及何时会发生这个错误吗？提前谢谢！

I am writing an app which listens tcp connection (see this example) . When a tcp connection disconnected I got error read tcp ip_server.:port1->ip_client:port2: wsarecv: An existing connection was forcibly closed by the remote host.
I expected error EOF and timeout(for conn.SetReadDeadline()) and tried to catch error with this code:
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
}
}
Anyone knows about this error? Do you know how to catch this error and when this error will occured ? Thanks in advance !

这个错误通常是由于您在连接已被对方关闭后发送了数据引起的。换句话说，这是一个应用程序协议错误。
英文:
The usual cause of this error is that you sent data over a connection which had already been closed by the peer. In other words, an application protocol error.
