標題: Qt TCP C/S通信源程序 tcp_Client與tcp_Server
TCP C/S 通信

源程序如下:
  1. #include "widget.h"
  2. #include "ui_widget.h"

  4. Widget::Widget(QWidget *parent) :
  5.     QWidget(parent),
  6.     ui(new Ui::Widget)
  7. {
  8.     ui->setupUi(this);
  9.     tcpSocket = new QTcpSocket;
  10.     connect(tcpSocket,SIGNAL(connected()),this,SLOT(connect_success()));
  11.     tcpSocket->connectToHost("10.0.2.15",8888);
  12.     connect(tcpSocket,SIGNAL(readyRead()),this,SLOT(read_data()));
  13. }

  15. Widget::~Widget()
  16. {
  17.     delete ui;
  18. }

  20. void Widget::on_send_clicked()
  21. {
  22.     std::string msg = ui->msg->text().toStdString();
  23.     tcpSocket->write(msg.c_str(),msg.size());
  24.     ui->msg->clear();
  25. }

  27. void Widget::read_data()
  28. {
  29.     char buf[256] = {};
  30.     tcpSocket->read(buf,sizeof(buf));
  31.     ui->text->append(buf);
  32. }

  34. void Widget::connect_success()
  35. {
  36.     ui->send->setEnabled(true);
  37. }

  39. void Widget::on_msg_returnPressed()
  40. {
  41.     char msg[256] = {};
  42.     sprintf(msg,"%s:%s",name,ui->msg->text().toStdString().c_str());
  43.     tcpSocket->write(msg,strlen(msg));
  44.     ui->msg->clear();
  45. }

  47. void Widget::on_name_returnPressed()
  48. {
  49.     sprintf(name,"%s",ui->name->text().toStdString().c_str());
  50.     qDebug("%s",name);
  51. }
