TCPGram

TCPGram

TCPGram是一个使用TCP时提供类似UDP的数据报（单个数据包）的库。这使您可以通过TCP提供的可靠性进行基于数据包的网络，而无需对UDP实现可靠性。

要求

TCPGram需要C ++ 11或更高版本以进行编译，并与Boost ASIO一起在大多数平台上编译而不会出现问题。

用法和示例

包括tcp_server.h和tcpgram.h设置AA服务器和

std::unordered_map<tcp::socket*, tcpgram*> g_clients;

// called to process a recieved datagram
bool process_datagram_server (tcp::socket* sock, raw_message* msg) {
	printf ( " SERVER Recieved datagram of %X bytes starting with %X, sending packet back... n " , msg-> m_size , msg-> m_buf [ 0 ]);
	g_clients[sock]-> send (msg);

	return true ;
}

// called when a new client is accepted
bool accept_client_callback (tcp::socket* sock) {
	g_clients[sock] = new tcpgram (sock, process_datagram_server, 0x8000 );
	return true ;
}

// called from tcp_server to recieve on a socket
bool read_socket_callback (tcp::socket* sock) {
	return g_clients[sock]-> recieve ();
}


void start_server () {
	tcp_server server = tcp_server (PORT, accept_client_callback, read_socket_callback);
	server. run ();
}

同样，使用TCPGram为客户端（使用Boost ASIO用于套接字）

 bool process_datagram_client (tcp::socket* sock, raw_message* msg) {
	printf ( " CLIENT Recieved datagram of %X bytes starting with %X n " , msg-> m_size , msg-> m_buf [ 0 ]);
	return true ;
}

void start_client () {
	boost::asio::io_context ctx;
	auto socket = new tcp::socket (ctx);
	
	boost:: system ::error_code error;
	boost::array< uint8_t , MAX_BUFLEN> buf;

	socket-> connect ( tcp::endpoint ( boost::asio::ip::address::from_string (IP, error), PORT), error);
	if (error) {
		printf ( " Failed to connect to server. n " );
	}

	tcpgram dgram = tcpgram (socket, process_datagram_client);

	auto msg = raw_message ();
	msg. put < uint8_t >( 10 ); // fill the message with random stuff
	msg. put_raw ( 0x6000 );

	dgram. send (&msg);

	while ( true ) // just keep trying to recieve
		dgram. recieve ();
}
