TCP方式的Socket

TCPServer要用TCP的客戶端來測試。POCO中TCP方式的Socket有：

Poco::Net::ServerSocket
Poco::Net::StreamSocket
Poco::Net::DialogSocket
Poco::Net::SecureServerSocket       ---相對於SSL
Poco::Net::SecureStreamSocket      ---相對於SSL

 1     ServerSocket svs(0);
 2     TCPServer srv(new TCPServerConnectionFactoryImpl<EchoConnection>(), svs);
 3     srv.start();
 4     SocketAddress sa("localhost", svs.address().port());
 5     StreamSocket ss1(sa);
 6     std::string data("hello, world");
 7     ss1.sendBytes(data.data(), (int) data.size());
 8     char buffer[256];
 9     int n = ss1.receiveBytes(buffer, sizeof(buffer));
10     cout<<"n = "<<n<<endl;
11     ss1.close();　　　

 1         EchoServer echoServer;
 2         DialogSocket ds;
 3         ds.connect(SocketAddress("localhost",echoServer.port()));
 4         ds.sendMessage("Hello,world!");
 5         std::string str;
 6         ds.receiveMessage(str);
 7         cout<<"str = "<<str<<endl;
 8 
 9         ds.sendMessage("KAREN","appinf.com");
10         ds.receiveMessage(str);
11         cout<<"str = "<<str<<endl;
12 
13         ds.sendMessage("220 Hello, world!");
14         int status = ds.receiveStatusMessage(str);
15         cout<<"status = "<<status<<endl;
16 
17         ds.sendString("220-line1\r\n220 line2\r\n");
18         status = ds.receiveStatusMessage(str);
19         cout<<"status = "<<status<<endl;
20         cout<<"str = "<<str<<endl;
