方案1

//bool tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port );//失败 没指定 是IPV4还是IPV6

方案2

//    QString string("192.168.112.10");

//    QHostAddress address(QHostAddress::LocalHost);//QHostAddress::Any

//    bool tf =address.setAddress( string );

//    tf =m_pSocket->bind(address,m_port );//失败

方案3

//    quint32 ip4Add = 192<<24|168<<16|112<<8|10;

//    QHostAddress address(QHostAddress::Any);//QHostAddress::LocalHost

//    address.setAddress( ip4Add );

//    bool tf =m_pSocket->bind(address,m_port );//失败

方案4

    //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port,QAbstractSocket::ReuseAddressHint| QAbstractSocket::ShareAddress | QAbstractSocket::DontShareAddress );//失败

 //tf =m_pSocket->bind(QHostAddress(ip4Add),m_port,QAbstractSocket::ReuseAddressHint| QAbstractSocket::ShareAddress | QAbstractSocket::DontShareAddress );

这共享和非共享明显时互斥的，这为啥这样测试  忘了

其他方案

    //quint32 ip4Add = 192<<24|168<<16|112<<8|100;

    //bool tf =m_pSocket->bind(QHostAddress(ip4Add),m_port,QAbstractSocket::ShareAddress );

//    tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port,QAbstractSocket::ReuseAddressHint );

//    tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port,QAbstractSocket::ShareAddress  );

//    tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port,QAbstractSocket::DontShareAddress );

    //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port,QAbstractSocket::ReuseAddressHint | QAbstractSocket::ShareAddress  );

    //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port,QAbstractSocket::DontShareAddress | QAbstractSocket::ReuseAddressHint  );

    //tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port,QAbstractSocket::DontShareAddress | QAbstractSocket::ShareAddress  );

    //m_pSocket->bind(QHostAddress::Any, m_port );//方便使用
