설치

Capgo의 AI 보조 설치를 사용하여 플러그인을 설치할 수 있습니다. AI 도구에 Capgo 기능을 추가하려면 다음 명령어를 사용하세요:

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

다음 명령어를 사용하세요:

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

만약 Manual Setup을 선호한다면, 플러그인을 설치하기 위해 다음 명령어를 실행하고 아래의 플랫폼별 지침을 따르세요:

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

import

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

API 개요

isAvailable

비омет릭 인증 장치가 사용 가능한지 확인합니다.

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

await NativeBiometric.isAvailable();

verifyIdentity

사용자가 비омет릭 인증을 통해 인증하도록 유도합니다.

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

await NativeBiometric.verifyIdentity();

getCredentials

지정된 서버에 저장된 자격 증명을 가져옵니다.

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

await NativeBiometric.getCredentials({} as GetCredentialOptions);

setCredentials

해당 서버에 대한 주어진 자격 증명을 저장합니다.

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

await NativeBiometric.setCredentials({} as SetCredentialOptions);

deleteCredentials

해당 서버에 대한 저장된 자격 증명을 삭제합니다.

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

await NativeBiometric.deleteCredentials({} as DeleteCredentialOptions);

getSecureCredentials

해당 서버에 대한 저장된 자격 증명을 가져옵니다. 이 자격 증명은 BIOMETRY_CURRENT_SET 또는 BIOMETRY_ANY로 설정된 경우에만 사용할 수 있습니다.

iOS에서는 Keychain 항목에 접근할 때 자동으로 생체 인증 프롬프트를 표시합니다. Android에서는 자격 증명 해독 키에 CryptoObject를 바운드한 BiometricPrompt를 표시합니다.

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

await NativeBiometric.getSecureCredentials({} as GetSecureCredentialsOptions);

isCredentialsSaved

해당 서버에 대한 자격 증명이 이미 저장되어 있는지 확인합니다.

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

await NativeBiometric.isCredentialsSaved({} as IsCredentialsSavedOptions);
