Démarrage

Installer

Vous pouvez utiliser notre configuration assistée par l'IA pour installer le plugin. Ajoutez les Capgo compétences à votre outil IA en utilisant la commande suivante :

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

Ensuite, utilisez la prompt suivante :

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-native-biometric` plugin in my project.

Si vous préférez la configuration manuelle, installez le plugin en exécutant les commandes suivantes et suivez les instructions spécifiques au plateforme ci-dessous :

bun add @capgo/capacitor-native-biometric
bunx cap sync

Importer

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

API Aperçu

isAvailable

Vérifie si le matériel d'authentification biométrique est disponible.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.isAvailable();

verifyIdentity

Invite l'utilisateur à s'authentifier avec des biométriques.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.verifyIdentity();

getCredentials

Obtient les informations d'identification stockées pour un serveur donné.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.getCredentials({} as GetCredentialOptions);

setCredentials

Stocke les informations d'identification données pour un serveur donné.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.setCredentials({} as SetCredentialOptions);

deleteCredentials

Supprime les informations d'identification stockées pour un serveur donné.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.deleteCredentials({} as DeleteCredentialOptions);

getSecureCredentials

Obtient les informations d'identification stockées pour un serveur donné, nécessitant une authentification biométrique. Les informations d'identification doivent avoir été stockées avec accessControl défini sur BIOMETRY_CURRENT_SET ou BIOMETRY_ANY.

Sur iOS, le système montre automatiquement le prompt biométrique lors de l'accès à l'élément Keychain protégé. Sur Android, BiometricPrompt est affiché avec un CryptoObject lié à la clé de décryptage des informations d'identification.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.getSecureCredentials({} as GetSecureCredentialsOptions);

isCredentialsSaved

Vérifie si les informations d'identification sont déjà enregistrées pour un serveur donné.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.isCredentialsSaved({} as IsCredentialsSavedOptions);
