Qt TCP相关的一些整理：客户端常见操作 socket 通信 network代码示例

#include "tcpmainwindow.h" #include "ui_tcpmainwindow.h" #include <QDebug> TcpMainWindow::TcpMainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::TcpMainWindow) { ui->setupUi(this); m_client = new QTcpSocket(this); m_client->connectToHost("127.0.0.1",8898); if(m_client->waitForConnected()){ qDebug()<<"conn ok"; connect(m_client,SIGNAL(readyRead()),this,SLOT(myRead())); }else{ qDebug()<<"conn fail"<<m_client->errorString(); } } TcpMainWindow::~TcpMainWindow() { delete ui; } void TcpMainWindow::myRead() { QByteArray buffer = m_client->readAll(); qDebug()<<buffer; // 只是简单的打印输出，还没有做解包处理 } void TcpMainWindow::on_pushButton_clicked() { char buffer[] = "码蚁软件欢迎您"; qDebug()<<m_client->write(buffer,sizeof(buffer)); }
