Sida HTTP u Shaqeeyo
HTTP waxay ku shaqeysaa qaab codsi/jawaab. Macmiilku wuxuu u dirayaa codsi server-ka, server-kuna wuxuu soo celiyaa jawaab.
Tusaale:
- Macmiilku wuxuu codsadaa bogga internetka.
- Browser-ka wuxuu u diraa codsi HTTP server-ka.
- Server-ku wuxuu helaa codsiga wuxuuna soo celiyaa jawaab, oo ay ku jirto HTML-ka bogga.
- Browser-ka wuxuu turjumaa HTML-ka wuxuuna soo bandhigaa bogga.
Hababka HTTP (HTTP Methods)
Hababka HTTP waa amarro loo isticmaalo in lagu tilmaamo ficilka la rabo in lagu sameeyo kheyraadka. Qaar ka mid ah hababka ugu caansan waxaa ka mid ah:
