我正在開發一個3D(第一/第三人稱)遊戲,我試圖讓它使用TCP套接字進行多人遊戲。我爲此使用了boost asio庫,並且我略微超出了我的想象。我在boost asio文檔頁面上玩過一些教程和示例,他們編譯/運行/工作得很好,對於一切如何工作我都有點困惑。Boost Asio - 服務器沒有收到消息
現在我只是試圖讓服務器接受來自客戶端的消息,並在收到消息後打印消息。當我執行下面的代碼(它編譯/鏈接/運行正常)時,沒有任何反應。更具體地說,客戶端似乎成功發送消息,並且服務器似乎永遠不會收到消息。
客戶端代碼:
ClientFramework::ClientFramework() :
mResolver(mIOService)
{
}
bool ClientFramework::Initialize()
{
try
{
tcp::resolver::query query("localhost", "daytime");
tcp::resolver::iterator it = mResolver.resolve(query);
tcp::socket socket(mIOService);
boost::asio::connect(socket, it);
std::string s = "hello world";
boost::system::error_code e;
socket.write_some(boost::asio::buffer(s.c_str(), s.size()), e);
if (e)
{
throw boost::system::system_error(e);
}
} catch (std::exception& e)
{
gLog << LOG_ERROR << e.what() << "\n";
}
return true;
}
Server代碼:
ServerFramework::ServerFramework() :
mAcceptor(mIOService, tcp::endpoint(tcp::v4(), 13))
{
}
bool ServerFramework::Initialize()
{
mIOService.run();
StartAccept();
return true;
}
void ServerFramework::StartAccept()
{
Connection::ptr conn =
Connection::create(mAcceptor.get_io_service());
mAcceptor.async_accept(conn->Socket(),
boost::bind(&ServerFramework::HandleAccept, this, conn,
boost::asio::placeholders::error));
}
void ServerFramework::HandleAccept(Connection::ptr conn,
const boost::system::error_code& error)
{
if (!error)
{
conn->Initialize();
}
StartAccept();
}
Connection::ptr Connection::create(boost::asio::io_service& io_service)
{
return ptr(new Connection(io_service));
}
tcp::socket& Connection::Socket()
{
return mSocket;
}
void Connection::Initialize()
{
boost::asio::async_read(mSocket, boost::asio::buffer(buf, BUFFER_SIZE),
boost::bind(&Connection::handle_read, shared_from_this(),
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
}
Connection::Connection(boost::asio::io_service& io_service) :
mSocket(io_service)
{
}
void Connection::handle_read(const boost::system::error_code& e, size_t size)
{
std::string s(buf, size);
gLog << LOG_INFO << s << "\n";
boost::asio::async_read(mSocket, boost::asio::buffer(buf, BUFFER_SIZE),
boost::bind(&Connection::handle_read, shared_from_this(),
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
}
