其实这两者间的通信跟Linux的socket间通信没什么区别。

客户端：

//client.h

#ifndef CLIENT_H
#define CLIENT_H

#include <QtNetwork>
#include <QObject>
#include <QString>
#include <QTcpSocket>

class Client : public QObject
{
    Q_OBJECT
public:
    Client(QObject* parent = 0);
    ~Client();
    void start(QString address, quint16 port);

public slots:
    void startTransfer();
    void startRead();
    void connectError(QAbstractSocket::SocketError);

private:

    QTcpSocket client;

};

#endif // CLIENT_H

 

// client.cpp

#include "client.h"
#include <QHostAddress>
#include <string>
#include <iostream>
using namespace std;

Client::Client(QObject *parent) : QObject(parent)
{
    connect(&client, SIGNAL(connected()),
            this, SLOT(startTransfer()));
    connect(&client, SIGNAL(error(QAbstractSocket::SocketError)),
            this, SLOT(connectError(QAbstractSocket::SocketError)));
    connect(&client, SIGNAL(readyRead()),
            this, SLOT(startRead()));
}

Client::~Client()
{
    client.close();
}
