QT webservice服务端 代码？

以下是一个简单的QT webservice服务端代码示例：

#include <QtCore/QCoreApplication>
#include <QtNetwork>
#include <QtXmlPatterns>

class MyWebService : public QObject
{
    Q_OBJECT
public:
    MyWebService(QObject *parent = 0) : QObject(parent)
    {
        //创建QTcpServer监听来自客户端的请求
        tcpServer = new QTcpServer(this);
        connect(tcpServer, SIGNAL(newConnection()), this, SLOT(onNewConnection()));
        if (!tcpServer->listen(QHostAddress::Any, 8080)) {
            qCritical() << "Failed to start server:" << tcpServer->errorString();
        } else {
            qDebug() << "Server started";
        }
    }

private slots:
    void onNewConnection()
    {
        //接收来自客户端的请求
        QTcpSocket *clientConnection = tcpServer->nextPendingConnection();
        connect(clientConnection, SIGNAL(disconnected()), clientConnection, SLOT(deleteLater()));
        connect(clientConnection, SIGNAL(readyRead()), this, SLOT(onReadyRead()));
    }

    void onReadyRead()
    {
        //读取客户端请求的数据
        QTcpSocket *clientConnection = qobject_cast<QTcpSocket *>(sender());
        if (!clientConnection) {
            return;
        }

        QByteArray requestData = clientConnection->readAll();
        qDebug() << "Received request:" << requestData;

        //构造响应并发送给客户端
        QByteArray responseData = "<response>Hello, world!</response>";
        clientConnection->write(responseData);
        clientConnection->disconnectFromHost();
    }

private:
    QTcpServer *tcpServer;
};

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    //创建WebService并启动
    MyWebService webService;
    return a.exec();
}

#include "main.moc"

这个示例代码创建了一个QTcpServer对象来监听来自客户端的请求，并在接收到请求时构造响应并发送回客户端。您可以根据您的需求修改响应的内容。
