基于QT C++的TCP客户端

#include "mainwindow.h" #include "ui_mainwindow.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); client = new QTcpSocket(this); // 创还能客户端通信对象 client->connectToHost(QHostAddress("192.168.3.234"), 8080); client->write("hello"); connect(client, SIGNAL(readyRead()), this, SLOT(read_data())); } MainWindow::~MainWindow() { delete ui; } void MainWindow::read_data() { QString msg = client->readAll(); qDebug() << msg; }
