Ubuntu 16.04 Edition Qt Socket Project Windows 10 端的Socket Tool

整个界面的样式如图所示，包括了TCP Client以及TCP Server端。

IP表示客户端将要连接的TCP Server的服务器ip地址，PORT填入的是对应的TCP Server的地址开放的监听的端口号

Clear按钮是用来清楚Server或者Client的接收空间，Send是用来发送发送栏当中的数据的。其他按钮用来开启对应的服务。

Step2：相关槽函数已经接收读取函数的实现

void MainWindow::Client_Recieve_Data(void)

{

    QByteArray buf;

    buf = client->readAll();

    if(!buf.isEmpty())

    {

        QString str = this->ui->Client_Recieve->toPlainText();

        str += tr(buf);

        this->ui->Client_Recieve->clear();

        this->ui->Client_Recieve->appendPlainText(str);

    }

    buf.clear();

}

void MainWindow::on_Client_Button_clicked(bool checked)

{

    if(!ClientFlag)

    {

        QString IP,PORT;

        IP = this->ui->IP_Address->text();

        PORT = this->ui->Client_Port->text();

        qDebug() << IP;

        qDebug() << PORT;

        client->connectToHost(QHostAddress(IP),PORT.toInt(),QTcpSocket::ReadWrite);

        qDebug() << "Client is Started!";

        QObject::connect(client,&QTcpSocket::readyRead,this,&MainWindow::Client_Recieve_Data);

        this->ui->Client_Button->setStyleSheet("background-color: rgb(85,170,0);");

    }

    else

    {

        this->ui->Client_Button->setStyleSheet("background-color: rgb(0,0,0);");

        client->close();

        qDebug() << "Client is Closed!";

    }

    ClientFlag = !ClientFlag;

}

void MainWindow::on_pushButton_clicked(bool checked)

{

    if(ClientFlag)

    {

        QString Send_data;

        Send_data = this->ui->Client_Send->toPlainText();

        qDebug() << Send_data;

        client->write(Send_data.toLatin1());

        qDebug() << "Data sended!";

    }

}

void MainWindow::on_Client_Clear_clicked(bool checked)

{

    this->ui->Client_Recieve->clear();

    qDebug() << "Client_Recieve_CLear!";

}

/************************************************************

 * Server Side Programming!

 * The Qt Socket Programming have ever finished binding the port!

 * The accept func is trigger by a new connection signal!

 ***********************************************************/

void MainWindow::readClient(void)

{

    QByteArray buf;

    buf = client_connect->readAll();

    if(!buf.isEmpty())

    {

        QString str = this->ui->Server_Recieve->toPlainText();

        str += tr(buf);

        this->ui->Server_Recieve->clear();

        this->ui->Server_Recieve->appendPlainText(str);

    }

    buf.clear();

}

void MainWindow::accepConnection(void)

{

    client_connect = server->nextPendingConnection();

    QObject::connect(client_connect,&QTcpSocket::readyRead,this,&MainWindow::readClient);

}

void MainWindow::on_Server_Clear_clicked(bool checked)

{

    this->ui->Server_Recieve->clear();

    qDebug() << "Server_Recieve_Clear!";

}

void MainWindow::on_ServerSend_clicked(bool checked)

{

    if(ServerFlag)

    {

        QString SendData;

        SendData = this->ui->Server_Send->toPlainText();

        client_connect->write(SendData.toLatin1());

        qDebug() << SendData;

        qDebug() << "ServerData send!";

    }

}

void MainWindow::on_Server_Button_clicked(bool checked)

{

    if(!ServerFlag)

    {

        QString MonitorPort;

        MonitorPort = this->ui->Server_Port->text();

        int PortNum;

        PortNum = MonitorPort.toInt();

        server->listen(QHostAddress::Any,PortNum);

        QObject::connect(server,&QTcpServer::newConnection,this,&MainWindow::accepConnection);

        qDebug() << "Server Started!";

        qDebug() << "PortNum:" << PortNum;

        this->ui->Server_Button->setStyleSheet("background-color: rgb(85,170,0);");

    }

    else

    {

        this->ui->Server_Button->setStyleSheet("background-color: rgb(0,0,0);");

        client_connect->close();

        server->close();

        qDebug() << "Server Closed!";

    }

    ServerFlag = !ServerFlag;

}

Step3：槽函数的声明&Socket对象定义

private slots:

    void on_Client_Button_clicked(bool checked);

    void on_pushButton_clicked(bool checked);

    void Client_Recieve_Data(void);

    void accepConnection(void);

    void readClient(void);

    void on_Client_Clear_clicked(bool checked);

    void on_Server_Clear_clicked(bool checked);

    void on_ServerSend_clicked(bool checked);

    void on_Server_Button_clicked(bool checked);

    void TimeOutProcess(void);

private:

    Ui::MainWindow *ui;

    QTcpSocket *client;

    QTcpServer *server;

    QTcpSocket *client_connect;

    QTimer *TimeMonitor;

    bool ClientFlag = false;

    bool ServerFlag = false;

Step4：信号和槽的连接

connect(this->ui->Client_Button,SIGNAL(clicked(bool)),this,SLOT(on_Client_Button_clicked()));
connect(this->ui->pushButton,SIGNAL(clicked(bool)),this,SLOT(on_pushButton_clicked()));

connect(this->ui->Client_Clear,SIGNAL(clicked(bool)),this,SLOT(on_Client_Clear_clicked()));
connect(this->ui->Server_Clear,SIGNAL(clicked(bool)),this,SLOT(on_Server_Clear_clicked()));

connect(this->ui->ServerSend,SIGNAL(clicked(bool)),this,SLOT(on_ServerSend_clicked()));

connect(this->ui->Server_Button,SIGNAL(clicked(bool)),this,SLOT(on_Server_Button_clicked()));

connect(TimeMonitor,&QTimer::timeout,this,&MainWindow::TimeOutProcess);

完成上述操作，基本就完成了Qt Socket程序的功能。
