开始使用

安装

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

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手动设置，安装插件并运行以下命令并遵循以下平台特定的说明:

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

导入

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

API 简介

isAvailable

检查生物识别硬件是否可用。

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证。

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

await NativeBiometric.getCredentials({} as GetCredentialOptions);

setCredentials

为给定的服务器存储指定的凭据。

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。 凭据必须已存储并且访问控制设置为 BIOMETRY_CURRENT_SET 或 BIOMETRY_ANY。

在 iOS 上，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 CryptoObject 绑定到凭据解密密钥的提示。

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

await NativeBiometric.getSecureCredentials({} as GetSecureCredentialsOptions);

isCredentialsSaved

检查是否已为给定服务器保存凭据。

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

await NativeBiometric.isCredentialsSaved({} as IsCredentialsSavedOptions);
