foo_catnap 源码分析

foo_catpap 是一个 foobar2000 插件，用于通过 http 协议的方式控制播放器。

此工会使用了 Poco 库，使用了 Poco::Net 模块，简单的做一个 http 服务器

CatNapServer.cpp

#include "stdafx.h"

#include "CatNapServer.h"

#include "Poco/Net/HTTPServer.h"

#include "Poco/Net/HTTPServerParams.h"

#include <iostream>

#include "CatNapRequestHandlerFactory.h"

using Poco::Net::HTTPServer;

using Poco::Net::HTTPServerParams;

namespace CatNap {

CatNapServer::CatNapServer() : server(NULL)

{

}

void CatNapServer::start()

{

unsigned short port = 20402; // 0x4FB2

HTTPServerParams *params = new HTTPServerParams();

server = new HTTPServer(new CatNapRequestHandlerFactory(), port, params);

server->start();

}

void CatNapServer::stop()

{

if (server != NULL)

{

server->stop();

delete server;

}

}

} // namespace CatNap

CatNapRequestHandlerFactory.cpp

#include "stdafx.h"

#include "CatNapRequestHandlerFactory.h"

#include "RootRequestHandler.h"

#include "PlaybackEventsRequestHandler.h"

#include "PlaylistsRequestHandler.h"

#include "PlaylistsEventsRequestHandler.h"

using Poco::Net::HTTPRequestHandler;

using Poco::Net::HTTPServerRequest;

namespace CatNap {

CatNapRequestHandlerFactory::CatNapRequestHandlerFactory()

{

}

HTTPRequestHandler* CatNapRequestHandlerFactory::createRequestHandler(const HTTPServerRequest& request)

{

if (request.getURI() == "/")

return new RootRequestHandler();

else if (request.getURI() == "/playback/events")

return new PlaybackEventsRequestHandler(playbackFacade);

else if (request.getURI() == "/playlists")

return new PlaylistsRequestHandler();

else if (request.getURI() == "/playlists/events")

return new PlaylistsEventsRequestHandler();

else

return 0;

}

} // namespace CatNap

简单的生成一个 http 服务器，使用工厂来路由。
