网络调试助手和串口调试助手是一对的,用Qt开发项目与硬件通信绝大部分都是要么串口通信(RS232 RS485 Modbus等),要么就是网络通信(TCP UDP HTTP等),所以一旦涉及到这两方面,多多少少肯定离不开对应的调试助手协助进行程序的调试,尤其是硬件工程师,更加需要第三方的独立的调试工具来验证硬件工作是否正常,这可以大大避免扯皮的事情发生,既然第三方的工具测试下来没有问题,收发数据都正常的话,那基本上可以断定是软件的问题,此时估计软件工程师心里慌得一逼啊! 基本功能: 以上作品完整源码下载都在开源主页,会持续不断更新作品数量和质量,欢迎各位关注。
一、前言
二、代码思路
第一步:实例化对应的类 tcpSocket = new QTcpSocket(this); connect(tcpSocket, SIGNAL(connected()), this, SLOT(connected())); connect(tcpSocket, SIGNAL(error(QAbstractSocket::SocketError)), this, SLOT(disconnected())); connect(tcpSocket, SIGNAL(disconnected()), this, SLOT(disconnected())); connect(tcpSocket, SIGNAL(readyRead()), this, SLOT(readData())); tcpServer = new TcpServer(this); connect(tcpServer, SIGNAL(clientConnected(QString, int)), this, SLOT(clientConnected(QString, int))); connect(tcpServer, SIGNAL(clientDisconnected(QString, int)), this, SLOT(clientDisconnected(QString, int))); connect(tcpServer, SIGNAL(sendData(QString, int, QString)), this, SLOT(sendData(QString, int, QString))); connect(tcpServer, SIGNAL(receiveData(QString, int, QString)), this, SLOT(receiveData(QString, int, QString))); udpSocket = new QUdpSocket(this); connect(udpSocket, SIGNAL(readyRead()), this, SLOT(readData())); 第二步:收发数据 void frmTcpClient::readData() { QByteArray data = tcpSocket->readAll(); if (data.length() <= 0) { return; } QString buffer; if (App::HexReceiveTcpClient) { buffer = QUIHelper::byteArrayToHexStr(data); } else if (App::AsciiTcpClient) { buffer = QUIHelper::byteArrayToAsciiStr(data); } else { buffer = QString(data); } append(1, buffer); //自动回复数据,可以回复的数据是以;隔开,每行可以带多个;所以这里不需要继续判断 if (App::DebugTcpClient) { int count = App::Keys.count(); for (int i = 0; i < count; i++) { if (App::Keys.at(i) == buffer) { sendData(App::Values.at(i)); break; } } } } void frmUdpClient::readData() { QHostAddress host; quint16 port; QByteArray data; QString buffer; while (udpSocket->hasPendingDatagrams()) { data.resize(udpSocket->pendingDatagramSize()); udpSocket->readDatagram(data.data(), data.size(), &host, &port); if (App::HexReceiveUdpClient) { buffer = QUIHelper::byteArrayToHexStr(data); } else if (App::AsciiUdpClient) { buffer = QUIHelper::byteArrayToAsciiStr(data); } else { buffer = QString(data); } QString ip = host.toString(); ip = ip.replace("::ffff:", ""); if (ip.isEmpty()) { continue; } QString str = QString("[%1:%2] %3").arg(ip).arg(port).arg(buffer); append(1, str); if (App::DebugUdpClient) { int count = App::Keys.count(); for (int i = 0; i < count; i++) { if (App::Keys.at(i) == buffer) { sendData(ip, port, App::Values.at(i)); break; } } } } }
