poco websocket服务器

以下是使用C++ Poco库创建一个简单的WebSocket服务器的示例代码：

#include <iostream>
#include <Poco/Net/HTTPServer.h>
#include <Poco/Net/HTTPRequestHandlerFactory.h>
#include <Poco/Net/WebSocket.h>
#include <Poco/Net/HTTPServerRequest.h>
#include <Poco/Net/HTTPServerResponse.h>
#include <Poco/Net/HTTPRequestHandler.h>
#include <Poco/Net/HTTPServerParams.h>
#include <Poco/Net/ServerSocket.h>
#include <Poco/Util/ServerApplication.h>

using namespace Poco::Net;
using namespace Poco::Util;

class WebSocketRequestHandler : public HTTPRequestHandler
{
public:
    void handleRequest(HTTPServerRequest& request, HTTPServerResponse& response)
    {
        WebSocket ws(request, response);
        char buffer[1024];
        int flags;
        int n;

        do
        {
            n = ws.receiveFrame(buffer, sizeof(buffer), flags);
            ws.sendFrame(buffer, n, flags);
        } while (n > 0 && (flags & WebSocket::FRAME_OP_BITMASK) != WebSocket::FRAME_OP_CLOSE);
    }
};

class WebSocketRequestHandlerFactory : public HTTPRequestHandlerFactory
{
public:
    HTTPRequestHandler* createRequestHandler(const HTTPServerRequest& request)
    {
        return new WebSocketRequestHandler;
    }
};

class WebSocketServerApp : public ServerApplication
{
protected:
    int main(const std::vector<std::string>& args)
    {
        ServerSocket svs(9980);
        HTTPServer srv(new WebSocketRequestHandlerFactory, svs, new HTTPServerParams);

        srv.start();
        waitForTerminationRequest();
        srv.stop();

        return Application::EXIT_OK;
    }
};

int main(int argc, char** argv)
{
    WebSocketServerApp app;
    return app.run(argc, argv);
}

这段代码创建了一个简单的WebSocket服务器，它会接收客户端发送的消息，并将其原样返回给客户端。你可以根据自己的需求修改和扩展代码。
