Ce que fait l’outil
Une référence rapide et cherchable pour tous les codes de statut HTTP standard. Filtrez par classe (1xx-5xx) ou cherchez par code ou par mot-clé pour savoir ce que signifie un code, quand un serveur le renvoie et ce que le client doit faire. C’est la consultation rapide vers laquelle les développeurs se tournent pendant le débogage, la conception d’API et la réponse aux incidents.
Comment l’utiliser
- Cherchez par code (p. ex.
404) ou par mot-clé (p. ex.redirect,teapot). - Utilisez le sélecteur de classe (Toutes / 1xx / 2xx / 3xx / 4xx / 5xx) pour affiner par catégorie.
- Touchez Copy sur n’importe quel code pour copier
"code reason".
Exemples
200 OK- la requête a réussi (2xx Succès).301 Moved Permanently- la ressource a une nouvelle URL permanente (3xx Redirection).404 Not Found- le serveur n’a trouvé aucune ressource correspondante (4xx Erreur de client).503 Service Unavailable- le serveur est surchargé ou indisponible pour maintenance (5xx Erreur de serveur).
Bon à savoir
