如何在qt中维护tcp套接字？

我在服务器端用以下代码重载了QTcpServer的incomingConnection函数

void CtiServer::incomingConnection(int socketDescriptor)
{
    qDebug() << QString("CtiServer thread id = %1, thread = %2").arg(QString::number((uint)QThread::currentThreadId(), 16)).arg(QString::number((qlonglong)QThread::currentThread(), 16));
    ServerThread *thread = new ServerThread(socketDescriptor, this);
    connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater()));
    thread->start();
}

您应该使用Client SIGNAL disconnected（）并将其连接到服务器端，而不是

sock.waitForDisconnected（-1）

；按照skg的说法，并通过在函数末尾调用exec（）进入线程的事件循环。waitForDisconnected正在阻止调用，因此套接字线程在套接字断开连接之前不会进行任何处理

void ServerThread::run()
{
    qDebug() << QString("ServerThread thread id = %1, thread = %2").arg(QString::number((uint)QThread::currentThreadId(), 16)).arg(QString::number((qlonglong)QThread::currentThread(), 16));
    serverSocket = new ServerSocket();
    serverSocket->setSocketDescriptor(socketDescriptor);
    connect(serverSocket, SIGNAL(readyRead()), serverSocket, SLOT(handleRequest()));
    serverSocket->waitForDisconnected(-1);
}

sock.disconnectFromHost();
sock.waitForDisconnected();
