安装

您可以使用我们的 AI 助手设置来安装插件。将 Capgo 技能添加到您的 AI 工具中，使用以下命令：

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

然后使用以下提示：

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

如果您prefer Manual Setup，安装插件并运行以下命令并遵循以下平台特定说明：

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

导入

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

API概述

isAvailable

检查生物识别认证硬件是否可用。

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

await NativeBiometric.isAvailable();

verifyIdentity

提示用户使用生物识别进行身份验证。

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

await NativeBiometric.verifyIdentity();

getCredentials

获取给定服务器的存储凭据。

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

await NativeBiometric.getCredentials({} as GetCredentialOptions);

setCredentials

为给定服务器存储给定凭据。

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

await NativeBiometric.setCredentials({} as SetCredentialOptions);

deleteCredentials

删除给定服务器的存储凭据。

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

await NativeBiometric.deleteCredentials({} as DeleteCredentialOptions);

getSecureCredentials

获取给定服务器的存储凭据，需要生物识别验证。 凭据必须已设置访问控制为BIOMETRY_CURRENT_SET或BIOMETRY_ANY。

iOS系统会自动显示生物识别提示符来访问受保护的Keychain项。 在Android上，BiometricPrompt会显示一个与凭据解密密钥绑定的CryptoObject。

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

await NativeBiometric.getSecureCredentials({} as GetSecureCredentialsOptions);

isCredentialsSaved

检查给定服务器的凭据是否已经保存。

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

await NativeBiometric.isCredentialsSaved({} as IsCredentialsSavedOptions);
