httprequest = HttpRequest("127.0.0.1", "3777")
En GET
httprequest.get('http://www.google.fr') httprequest.get('http://blog.hio.fr') httprequest.get('http://blog.hio.fr/blu.html') httprequest.get('http://blog.if-else.fr')
Renvoi

En POST
params = {"login":"login", "password":"password"} httprequest.post('http://www.url-bidon.fr/login/connexion', params)
Renvoi par exemple
url: http://www.url-bidon.fr/login/connexion, 302 Moved Temporarily
Et si on veut en savoir plus on a les fonctions getresponse() et getcontent()
httprequest.getresponse()
