使用Qt編寫聊天。有問題。我的客戶端的QTcpSocket保持連接狀態,但服務器發出newConnection()信號。網絡會話不是必需的。這是爲什麼?下面是一些代碼:QTcpSocket問題
ChatClient::ChatClient(QObject *parent)
: QObject(parent) {
tcpSocket = new QTcpSocket(this);
QNetworkConfigurationManager manager;
if (QNetworkConfigurationManager::NetworkSessionRequired
& manager.capabilities()) {
qDebug() << "Network session required";
}
connect(tcpSocket, SIGNAL(error(QAbstractSocket::SocketError)),
this, SLOT(error(QAbstractSocket::SocketError)));
connect(tcpSocket, SIGNAL(connected()),
this, SLOT(requestForID()));
connect(tcpSocket, SIGNAL(readyRead()),
this, SLOT(receiveMessage()));
tcpSocket->connectToHost("192.168.0.100", PORT);
}
void ChatClient::requestForID() {
qDebug() << "Connected, requesting for ID";
QByteArray segment;
QDataStream out(&segment, QIODevice::WriteOnly);
out.setVersion(QDataStream::Qt_4_7);
out << (quint16)0 << ID;
out.device()->seek(0);
out << (quint16)(segment.size() - sizeof(quint16));
tcpSocket->write(segment);
}
requestForID()是從來沒有被執行
ChatServer::ChatServer(QObject *parent)
: QObject(parent) {
tcpServer = new QTcpServer(this);
if (!tcpServer->listen(QHostAddress::Any, PORT)) {
qDebug() << "Unable to start the server"
<< tcpServer->errorString();
}
qDebug() << "Server port" << tcpServer->serverPort();
connect(tcpServer, SIGNAL(newConnection()),
this, SLOT(processConnection()));
}
void ChatServer::processConnection() {
qDebug() << "Incoming connection";
QTcpSocket *clientSocket = tcpServer->nextPendingConnection();
/*connect(clientSocket, SIGNAL(readyRead()),
this, SLOT(readData()));
readData(clientSocket);
connect(clientSocket, SIGNAL(disconnected()),
clientSocket, SLOT(deleteLater()));*/
QByteArray segment;
QDataStream out(&segment, QIODevice::WriteOnly);
out.setVersion(QDataStream::Qt_4_7);
out << (quint16)0 << (quint16)Message
<< "Successfully connected";
out.device()->seek(0);
out << (quint16)(segment.size() - sizeof(quint16));
clientSocket->write(segment);
clientSocket->disconnectFromHost();
}
服務器顯示傳入的連接和客戶端不發射連接其餘處於連接狀態,那並不接收服務器消息以及.. 。 有什麼想法?
