QUdpSocket bind 问题

//bool tf =m_pSocket->bind(QHostAddress("192.168.112.100"),m_port );//失败 

//    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

//    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

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

//    bool tf =m_pSocket->bind(QHostAddress(ip4Add),m_port );//失败

  //bool tf =m_pSocket->bind(QHostAddress("127.0.0.1"),m_port );//成功IPV4和IPV6, 收不到 外机发送的数据

    //bool tf =m_pSocket->bind(QHostAddress::LocalHost,m_port );//成功 ipv4,收不到 外机发送的数据

    bool tf =m_pSocket->bind(QHostAddress::Any,m_port );//成功
