在Qt的多线程网络通信中一个TCPSocket怎么实现读和写？

关键部分代码这是服务器的代码，对run函数的重新实现；void TcpThread::run(){ tcpSocket = new QTcpSocket; //将Server传来的socketfd与刚创建的tcpSocket关联 if(!tcpSocket->setSocketDescriptor(socketfd)) { emit error(tcpSocket->error()); return ; } in.setVersion(QDataStream::Qt_5_1); in.setDevice(tcpSocket); connect(tcpSocket,SIGNAL(readyRead()),this,SLOT(receiveMessage()),Qt::BlockingQueuedConnection); connect(tcpSocket,SIGNAL(stateChanged(QAbstractSocket::SocketState)),this, SLOT(statechanged()),Qt::BlockingQueuedConnection); exec();}登陆函数void TcpThread::UserLogin(){ QString account,passwd; //接收 in>>account>>passwd;//QDataStream in FindUser(account.toUInt(),0,&user); if(user.PASSWD == passwd) { qDebug()<<"login success"; //发送 QByteArray outblock; QDataStream out(&outblock,QIODevice::WriteOnly); out.setVersion(QDataStream::Qt_5_1); out<<int(0x0001)<<int(0); tcpSocket->write(outblock); outblock.resize(0); }}当第一次调用的时候就出现警告：QObject: Cannot create children for a parent that is in a different thread.(Parent is QNativeSocketEngine(0x1aa34cc8), parent's thread is TcpThread(0x1aa3a328), current thread is QThread(0x3d4ae8)，但是服务器和客户端还是能够收到彼此发过去的数据，但是客户端再一次发送就不能响应了；我想通过一个线程实现客户端的读和写！该怎么改进？？？

你好 ，能开源你的代码不？感觉没看够啊。正好需要用到你上面的一些功能和技术，主要是多线程的socket。
