Flutter身份验证与KYC审核插件flutter_accura_kyc的使用
Flutter身份验证与KYC审核插件flutter_accura_kyc的使用
简介
flutter_accura_kyc 是一个基于 Accura Scan 的数字用户验证系统插件。它支持多种文档扫描功能，包括 MRZ、OCR、条形码、银行卡等，并且可以用于身份验证和 KYC 审核。
安装
在 pubspec.yaml 文件中添加以下依赖：
flutter pub add flutter_accura_kyc或者通过本地路径安装：
flutter pub add <绝对路径到(flutter_accura_kyc)文件夹>注意事项：
下载插件后，可以通过本地路径将 flutter_accura_kyc 添加到项目中。
安卓配置
权限设置
在 AndroidManifest.xml 文件中添加以下权限：
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />配置 Gradle
在根目录的 build.gradle 文件末尾添加 jcenter()：
buildscript {
repositories {
...
jcenter()
}
}
allprojects {
repositories {
...
jcenter()
}
}在 app/build.gradle 中设置 Accura SDK：
android {
defaultConfig {

}
}iOS 配置
权限设置
在 Info.plist 文件中添加以下权限：
<key>NSCameraUsageDescription</key>
<string>App usage camera for scan documents.</string>
<key>NSMicrophoneUsageDescription</key>
<string>App usage microphone for oral verification.</string>
<key>NSSpeechRecognitionUsageDescription</key>

<key>NSPhotoLibraryUsageDescription</key>
<string>App usage photos for get document picture.</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>App usage photos for save document picture.</string>设置 Accura 许可证
Accura 提供三种许可证以启用完整的功能。从 这里 生成自己的许可证。
许可证类型：
- key.license：必备许可证，用于初始化 Accura SDK。
- accuraface.license：用于人脸匹配百分比计算。
- accuraactiveliveness.license：用于活体检测。
安卓配置
将三个许可证放入 android/app/src/main/assets/ 目录中。
iOS 配置
在 Xcode 中将许可证拖入项目根目录，并确保勾选 “复制如果需要” 和 “项目名称”。
使用方法
导入库
在 Dart 文件中导入插件：
import 'package:flutter_accura_kyc/flutter_accura_kyc.dart';获取许可证配置
获取许可证的所有可用功能：
await FlutterAccuraKyc.getMetaData()
.then((value) => {
dynamic result = json.decode(value);
})
.onError((error, stackTrace) => {
print("Error: $error");
});设置自定义配置
为 Accura SDK 设置自定义消息和配置：

更多关于Flutter身份验证与KYC审核插件flutter_accura_kyc的使用的实战系列教程也可以访问 https://www.itying.com/category-92-b0.html
在Flutter应用中集成身份验证和KYC（Know Your Customer）审核功能，可以使用 flutter_accura_kyc 插件。这个插件通常用于与AccuraScan的KYC服务集成，以进行身份证件验证、人脸识别等操作。以下是如何使用 flutter_accura_kyc 插件的步骤：
1. 添加依赖
首先，在 pubspec.yaml 文件中添加 flutter_accura_kyc 插件的依赖：
dependencies:
flutter:
sdk: flutter
flutter_accura_kyc: ^1.0.0 # 请使用最新版本然后运行 flutter pub get 来安装依赖。
2. 配置插件
在 android/app/build.gradle 文件中，确保 minSdkVersion 至少为 21：
android {
defaultConfig {
minSdkVersion 21
...
}
...
}3. 初始化插件
在你的Flutter应用中初始化 flutter_accura_kyc 插件。通常，你需要在 main.dart 或某个初始化文件中进行初始化。
import 'package:flutter_accura_kyc/flutter_accura_kyc.dart';
void main() async {
WidgetsFlutterBinding.ensureInitialized();
// 初始化Accura KYC
await FlutterAccuraKyc.initialize(
licenseKey: 'YOUR_LICENSE_KEY', // 从AccuraScan获取的许可证密钥
country: 'US', // 默认国家代码
isShowLogs: true, // 是否显示日志
);
runApp(MyApp());
}4. 启动KYC流程
在你的应用中，你可以通过调用 startKyc 方法来启动KYC流程。通常，你会在用户点击某个按钮时触发这个流程。
import 'package:flutter/material.dart';
import 'package:flutter_accura_kyc/flutter_accura_kyc.dart';
class KycScreen extends StatelessWidget {
Future<void> startKyc() async {
try {
final result = await FlutterAccuraKyc.startKyc(
country: 'US', // 国家代码
documentType: 'PASSPORT', // 证件类型，如PASSPORT, DRIVING_LICENSE等
isShowLogs: true,
);
// 处理KYC结果
print('KYC Result: $result');
} catch (e) {
print('KYC Error: $e');
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('KYC Verification'),
),
body: Center(
child: ElevatedButton(
onPressed: startKyc,
child: Text('Start KYC'),
),
),
);
}
}5. 处理KYC结果
startKyc 方法会返回一个包含KYC结果的对象。你可以根据返回的结果进行进一步的处理，例如将结果发送到服务器或显示给用户。
final result = await FlutterAccuraKyc.startKyc(
country: 'US',
documentType: 'PASSPORT',
isShowLogs: true,
);
if (result['status'] == 'SUCCESS') {
// KYC成功
print('KYC Successful: ${result['data']}');
} else {
// KYC失败
print('KYC Failed: ${result['error']}');
}6. 其他功能
flutter_accura_kyc 插件可能还提供其他功能，例如人脸识别、OCR（光学字符识别）等。你可以根据插件的文档来使用这些功能。
7. 注意事项
- 许可证密钥：你需要从AccuraScan获取有效的许可证密钥。
- 网络连接：KYC流程通常需要网络连接，确保设备在启动KYC时处于联网状态。
- 权限：确保你的应用已经请求了必要的权限，例如相机权限、存储权限等。
8. 调试与日志
在开发过程中，你可以启用日志来帮助调试。通过设置 isShowLogs 为 true，你可以在控制台中看到详细的日志信息。
await FlutterAccuraKyc.initialize(
licenseKey: 'YOUR_LICENSE_KEY',
country: 'US',
isShowLogs: true,
);9. 发布应用
在发布应用之前，确保你已经禁用了调试日志，并且使用了正确的生产环境许可证密钥。
await FlutterAccuraKyc.initialize(
licenseKey: 'YOUR_PRODUCTION_LICENSE_KEY',
country: 'US',
isShowLogs: false,
);
