要在Qt C++中实现一个简单的HTTP服务器，你可以使用Qt的网络模块来处理网络通信。以下是一个基本的示例代码，演示了如何创建一个简单的HTTP服务器：
#include <QCoreApplication>
#include <QTcpServer>
#include <QTcpSocket>
class HttpServer : public QTcpServer {
Q_OBJECT
public:
explicit HttpServer(QObject *parent = nullptr) : QTcpServer(parent) {}
protected:
void incomingConnection(qintptr socketDescriptor) override {
QTcpSocket *client = new QTcpSocket(this);
client->setSocketDescriptor(socketDescriptor);
connect(client, &QTcpSocket::readyRead, this, [client]() {
while (client->canReadLine()) {
QByteArray request = client->readLine().trimmed();
// 处理HTTP请求
qDebug() << "Received HTTP Request: " << request;
// 发送HTTP响应
QString response = "HTTP/1.1 200 OK\r\nContent-Length: 5\r\n\r\nHello";
client->write(response.toUtf8());
client->flush();
client->waitForBytesWritten();
}
client->close();
});
connect(client, &QTcpSocket::disconnected, client, &QTcpSocket::deleteLater);
}
};
int main(int argc, char *argv[]) {
QCoreApplication app(argc, argv);
HttpServer server;
if (!server.listen(QHostAddress::Any, 8080)) {
qCritical() << "Failed to start server";
return -1;
}
qDebug() << "HTTP Server listening on port" << server.serverPort();
return app.exec();
}
#include "main.moc"
这段代码创建了一个继承自QTcpServer的HttpServer类，在其中重写了incomingConnection()方法来处理新连接，并在该连接上接收和发送简单的HTTP请求和响应。请注意，这只是一个简单示例，实际生产环境中还需要更多功能和安全性考虑。
