Abstract

La présente demande se rapporte au domaine technique du traitement de données et concerne un procédé et un appareil de détection de données de mémoire cache, un dispositif informatique et un support de stockage. Le procédé consiste : lorsqu'une demande de détection de mémoire cache d'entrée est reçue, à acquérir un script de détection de mémoire cache correspondant à des informations d'élément ; à exécuter le script de détection de mémoire cache et à acquérir un code js d'un élément cible ; à générer un arbre de syntaxe abstraite correspondant au code js ; à parcourir tous les objets dans l'arbre de syntaxe abstraite et à acquérir une première clé de chaque premières données de mémoire cache comprises dans le code js ; à acquérir une deuxième clé de secondes données de mémoire cache soumises à un effacement de mémoire cache ; et sur la base d'une troisième clé qui est comprise dans un premier réseau et ne correspond pas à la deuxième clé, à acquérir et à afficher des données de cache cibles correspondant à la troisième clé. Au moyen de la présente demande, des données de mémoire cache cibles dans une mémoire cache locale qui n'est pas effacée peuvent être rapidement détectées. La présente demande peut également être appliquée au domaine des chaînes de blocs. Des données telles que les données de mémoire cache cibles peuvent être stockées sur une chaîne de blocs.
