Mi clase HTTP + winsock peticion HTTP ejemplo
« en: 26 Diciembre 2014, 18:08 pm »
Hola acabo de hacer una clase para organizar mas o menos el header de una peticion HTTP. Como esto:

Citar
HTTP/1.1 200 OK\r\n
Date: Mon, 23 May 2005 22:38:34 GMT\r\n
Server: Apache/1.3.3.7 (Unix) (Red-Hat/Linux)\r\n
Last-Modified: Wed, 08 Jan 2003 23:11:55 GMT\r\n
ETag: "3f80f-1b6-3e1cb03b"\r\n
Content-Type: text/html; charset=UTF-8\r\n
Content-Length: 131\r\n
Connection: close\r\n
\r\n

Ahora haz para que todo el proceso de winsock lo lleve la clase (u otra clase/función aparte)

En vez de define, tal vez te interesa más hacer un enum :o
