A cosa serve
Ogni risposta HTTP porta un codice di stato a tre cifre che dice al client cosa è successo: 2xx per il successo, 3xx per una redirezione, 4xx per un errore del client, 5xx per un guasto del server. Questo strumento raccoglie i codici registrati presso IANA insieme a una descrizione in linguaggio semplice, così puoi verificare il significato di un codice o trovare quello giusto da restituire senza uscire dal tuo editor.
Come si usa
- Digita un codice di stato, il suo nome, oppure una parola chiave come "rate limit".
- Se vuoi, restringi i risultati a una sola categoria (1xx–5xx).
- Leggi la breve spiegazione del codice corrispondente.
Privacy
Questo strumento funziona interamente nel tuo browser. Quello che inserisci non viene mai caricato, salvato o condiviso: chiudendo la scheda sparisce.
Domande frequenti
- Da dove viene questo elenco?
- Da una tabella locale dei codici registrati presso IANA, che copre ogni codice restituito da una tipica API web o interazione con il browser. Non effettua alcuna chiamata a un server.
- Qual è la differenza tra 401 e 403?
- 401 Unauthorized significa che la richiesta necessita di credenziali di autenticazione valide; 403 Forbidden significa che il server ha capito chi sei ma rifiuta comunque di autorizzare l'azione.
- Perché esiste il 418?
- "I'm a Teapot" deriva da una RFC del pesce d'aprile del 1998. Viene usato raramente sul serio, anche se alcune API lo usano come easter egg.
