Question

我在Windows 7上编写了TcpServer。Qt 5.7

当我使用Telnet连接到127.0.0.1和端口4545时，服务器正常工作

TCPSERVER：

_dataChannel = new QTcpServer(this);
connect(_dataChannel, QTcpServer::newConnection, this, &TCPTransfer::startDataSession);
if(!_dataChannel->listen(QHostAddress::Any, _dataPort))
{
    throw TCPException(QString("Can't start listen on %1").arg(_dataPort));
}
qDebug() << "TcpTransfer:: Data channel was start at " << _dataChannel->serverAddress() << " : " << _dataChannel->serverPort();
//...
void TCPTransfer::startDataSession()
{
    _dataSocket = _dataChannel->nextPendingConnection();
    qDebug() << "TcpTransfer:: Data socket was created";
    if(!_dataSocket->open(QIODevice::ReadWrite))
    {
        emit TCPException("Can't open data socket for Read/Write");
        return;
    }
    qDebug() << "TcpTransfer:: Data socket was opened";
    connect(_dataSocket, &QTcpSocket::disconnected, _dataSocket, &QTcpSocket::deleteLater);
    connect(_dataSocket, &QTcpSocket::readyRead, this, &TCPTransfer::receiveData);
}
//...
void TCPTransfer::receiveData()
{
    QByteArray data;
    while(_dataSocket->bytesAvailable() > 0)
    {
        data.append(_dataSocket->readAll());
        if(data.isEmpty())
        {
            emit ErrorOccurred("Can't read TCP buffer");
            return;
        }
    }
    qDebug() << "TcpTransfer:: Data received: " << data;
    emit newTCPData(data);
}

但是，当我尝试从测试方法（#include <QTest>连接所有正在运行的测试private slots中的TestTcpServer）到服务器连接时，永远不会从QAbstractSocket::ConnectingState变为{{{} 1}}和QAbstractSocketConnectedState信号永远不会发出。

我不知道，这是因为插槽，还是因为测试，或其他什么！

TcpClient代码：

connected()

QTcpSocket永远不会发出＆＃34; connected＆＃34;
