QTcpServer listen失败 情景记录:项目中发现自己的电脑IP和端口配置都没有问题,udp等其它通信方式都没有问题,但是使用QTcpServer的类对象绑定ip和端口的时候总是失败。通过打印错误信息排查,QTcpServer::errorString(),显示:The address is not available(不是代码问题,也不是IP地址和端口号的填写问题) 解决办法:重...

Reimplement this function to alter the server's behavior when a connection is available. If this server is using QNetworkProxy then the socketDescriptor may not be usable with native socket functions, and should only be used with QTcpSocket::setSocketDescriptor(). ...

If an error occurs, serverError() returns the type of error, and errorString() can be called to get a human readable description of what happened. When listening for connections, the address and port on which the server is listening are available as serverAddress() and serverPort(). ...
