websocket++库有大量消息过来，用消息队列处理消息，且可以和多个客户端进行对应交互，qtc++代码-Go服务器开发

以下是一个使用 WebSocket++ 库和 Qt 的 C++ 代码示例，用于创建一个基于 WebSocket 的服务器，并使用消息队列处理大量消息并与多个客户端进行交互：

#include <iostream>
#include <queue>
#include <mutex>
#include <websocketpp/config/asio_no_tls.hpp>
#include <websocketpp/server.hpp>
#include <QCoreApplication>
#include <QObject>
#include <QString>
typedef websocketpp::server<websocketpp::config::asio> Server;
typedef websocketpp::connection_hdl ConnectionHandle;
std::queue<std::pair<ConnectionHandle, std::string>> messageQueue;
std::mutex queueMutex;
class WebSocketServer : public QObject {
    Q_OBJECT
public:
    explicit WebSocketServer(QObject* parent = nullptr) : QObject(parent) {}
public slots:
    void onMessage(Server* server, ConnectionHandle hdl, websocketpp::server<websocketpp::config::asio>::message_ptr msg) {
        std::string message = msg->get_payload();
        // 在这里编写具体的消息处理逻辑
        // 这里只是简单地将接收到的消息转换为大写并发送回客户端
        std::transform(message.begin(), message.end(), message.begin(), ::toupper);
        server->send(hdl, message, websocketpp::frame::opcode::text);
    }
    void processMessages() {
        while (true) {
            if (!messageQueue.empty()) {
                std::lock_guard<std::mutex> lock(queueMutex);
                auto [hdl, message] = messageQueue.front();
                messageQueue.pop();
                // 在这里根据具体需求处理待发送的消息
                // 示例：向所有客户端广播消息
                for (auto it = server.get_conns().begin(); it != server.get_conns().end();) {
                    if (it->second.lock()) {
                        server.send(it->first, message, websocketpp::frame::opcode::text);
                        ++it;
                    } else {
                        it = server.get_conns().erase(it);
                    }
                }
                // 示例：向指定客户端发送消息
                // server.send(hdl, message, websocketpp::frame::opcode::text);
            }
            QCoreApplication::processEvents();
        }
    }
private:
    Server server;
};
int main(int argc, char** argv) {
    QCoreApplication app(argc, argv);
    WebSocketServer wsServer;
    try {
        wsServer.server.set_message_handler([&wsServer](auto hdl, auto msg) { wsServer.onMessage(&wsServer.server, hdl, msg); });
        wsServer.server.init_asio();
        wsServer.server.listen(9002);
        wsServer.server.start_accept();
        std::thread t([&wsServer]() { wsServer.processMessages(); });
        int result = app.exec();
        t.join();
        return result;
    } catch (const std::exception& e) {
        std::cout << "Exception: " << e.what() << std::endl;
    }
    return 0;
}
