Qt写的一个server程序

#include "mainwindow.h" #include "ui_mainwindow.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); } MainWindow::~MainWindow() { delete ui; } RestfulServer::RestfulServer(QObject *parent) : QTcpServer(parent) { } void RestfulServer::incomingConnection(qintptr socketDescriptor) { QTcpSocket* socket = new QTcpSocket(this); socket->setSocketDescriptor(socketDescriptor); connect(socket, SIGNAL(readyRead()), this, SLOT(handleRequest())); // Store the socket in a list for future reference m_clients.append(socket); } void RestfulServer::handleRequest() { QTcpSocket* socket = qobject_cast<QTcpSocket*>(sender()); if (!socket) return; QByteArray requestData = socket->readAll(); QString request = QString::fromLatin1(requestData.constData()); // 将请求分成请求行、请求头和请求体 QStringList lines = request.split("\r\n"); QString requestLine = lines.first(); lines.removeFirst(); // 解析请求行并从中提取请求方法、请求路径和请求协议 QStringList parts = requestLine.split(" "); QString method = parts[0]; QString path = parts[1]; // 从请求路径中提取参数 QUrl url(path); QString query = url.query(); QUrlQuery urlQuery(query); // 构造响应 QString response; if (path == "/hello") { response = "HTTP/1.1 200 OK\r\n" "Content-Type: text/plain\r\n" "Content-Length: 12\r\n" "\r\n" "Hello World!"; } else if (path == "/good") { response = "HTTP/1.1 200 OK\r\n" "Content-Type: text/plain\r\n" "Content-Length: 12\r\n" "\r\n" "Hello_World!"; } else { response = "HTTP/1.1 404 Not Found\r\n" "Content-Type: text/plain\r\n" "Content-Length: 9\r\n" "\r\n" "Not found"; } socket->write(response.toLatin1()); socket->flush(); socket->waitForBytesWritten(); socket->close(); }
