Qt使用QWebsocket实现服务端和客户端通信

#include "mainwindow.h" #include "ui_mainwindow.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); setWindowTitle(QStringLiteral("服务端")); m_WebSocketServer = new QWebSocketServer("server", QWebSocketServer::NonSecureMode); connect(m_WebSocketServer, SIGNAL(newConnection()), this, SLOT(onNewConnection())); connect(ui->startButton, SIGNAL(clicked(bool)), this, SLOT(onStartButtonClick())); connect(ui->stopButton, SIGNAL(clicked(bool)), this, SLOT(onStopButtonClick())); connect(ui->cleanButton, SIGNAL(clicked(bool)), this, SLOT(onCleanButtonClick())); connect(ui->sendButton, SIGNAL(clicked(bool)), this, SLOT(onSendButtonClick())); } MainWindow::~MainWindow() { delete ui; } void MainWindow::onStartButtonClick() { int i_port = ui->monitorSpinBox->text().toInt(); m_WebSocketServer->listen(QHostAddress::Any, i_port); ui->startButton->setEnabled(false); ui->stopButton->setEnabled(true); } void MainWindow::onStopButtonClick() { ui->startButton->setEnabled(true); ui->stopButton->setEnabled(false); m_WebSocketServer->close(); } void MainWindow::onSendButtonClick() { QString msg = ui->sendTextedit->document()->toPlainText(); for (int i=0;i<m_clients.size();i++) { m_clients.at(i)->sendTextMessage(msg); } } void MainWindow::onCleanButtonClick() { ui->receiveTextEdit->clear(); } void MainWindow::onNewConnection() { ui->startButton->setEnabled(false); ui->stopButton->setEnabled(true); ui->sendTextedit->setEnabled(true); ui->sendButton->setEnabled(true); ui->cleanButton->setEnabled(true); pSocket = m_WebSocketServer->nextPendingConnection(); connect(pSocket, SIGNAL(textMessageReceived(QString)), this, SLOT(processTextMessage(QString))); connect(pSocket, SIGNAL(disconnected()), this, SLOT(socketDisconnected())); QString item = pSocket->peerAddress().toString(); ui->linkclientListWidget->addItem(item); m_clients << pSocket; } void MainWindow::processTextMessage(QString message) { QString time = current_date_time->currentDateTime().toString("yyyy.MM.dd hh:mm:ss.zzz ddd"); QString item = pSocket->peerAddress().toString(); ui->receiveTextEdit->append(time + "" + item + "\n" + message); } void MainWindow::socketDisconnected() { ui->startButton->setEnabled(true); ui->stopButton->setEnabled(false); ui->sendButton->setEnabled(false); ui->sendTextedit->setEnabled(false); ui->receiveTextEdit->setEnabled(false); ui->cleanButton->setEnabled(false); }
