Anleitung zum Start

Installieren

Sie können unsere AI-gestützte Einrichtung verwenden, um das Plugin zu installieren. Fügen Sie den Capgo-Fähigkeiten Ihrer AI-Werkzeug mit der folgenden Befehl hinzu:

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

Verwenden Sie dann die folgende Anfrage:

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

Wenn Sie eine manuelle Einrichtung bevorzugen, installieren Sie das Plugin, indem Sie die folgenden Befehle ausführen und die darunter angegebenen Plattform-spezifischen Anweisungen befolgen.

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

Importieren

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

API Übersicht

isAvailable

Überprüft, ob Biometrie-Hardware verfügbar ist.

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

const result = await NativeBiometric.isAvailable();
console.log(result);

verifyIdentity

Bittet den Benutzer um eine Authentifizierung mit Biometrien.

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

await NativeBiometric.verifyIdentity();

getCredentials

Ermittelt die gespeicherten Anmelddaten für einen bestimmten Server.

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

const result = await NativeBiometric.getCredentials({ server: 'example.com' });
// The result holds sensitive values: use it without logging it.

setCredentials

Stores the given credentials for a given server.

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

await NativeBiometric.setCredentials({
  username: 'username',
  password: 'password',
  server: 'example.com',
});

deleteCredentials

Löscht die gespeicherten Anmeldeinformationen für einen bestimmten Server.

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

await NativeBiometric.deleteCredentials({ server: 'example.com' });

getSecureCredentials

Gets the stored credentials for a given server, requiring biometric authentication. Credentials must have been stored with accessControl set to BIOMETRY_CURRENT_SET or BIOMETRY_ANY.

Bei iOS zeigt das System automatisch den biometrischen Prompt an, wenn auf das geschützte Keychain-Element zugegriffen wird. Bei Android wird der BiometricPrompt mit einem CryptoObject angezeigt, das an die Schlüsseldekryptierung gebunden ist.

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

const result = await NativeBiometric.getSecureCredentials({ server: 'example.com' });
// The result holds sensitive values: use it without logging it.

isCredentialsSaved

Überprüft, ob Anmeldeinformationen bereits für einen bestimmten Server gespeichert sind.

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

const result = await NativeBiometric.isCredentialsSaved({ server: 'example.com' });
console.log(result);
