项目中有实名认证的需求,用户上传身份证反正面,进行人脸核验,后台集成的是阿里云的金融级实名认证SDK,巧合的是阿里云没有packages 需要自己造轮子。
废话不多少,直接上代码:
新建项目 ProjectType = Plugin
创建完成后,会自动为我们搭建好通信结构
编写Dart中间件
在项目下的 lib下的dart文件中定义我们的通信方法。
实名认证 需要两个方法 分别是:
获取本机信息发送给服务器 返回ID
调用实名认证,以及返回结果
import 'dart:async';
import 'package:flutter/services.dart';
class AliAuthPerson {
static const MethodChannel _channel = MethodChannel('ali_auth_person');
static Future<String?> get platformVersion async {
final String? version = await _channel.invokeMethod('getPlatformVersion');
return version;
}
static const EventChannel _eventChannel =
EventChannel("ali_auth_person_plugin_event");
///认证结果返回监听
static addListen(Function(String resData) onEvent) {
_eventChannel.receiveBroadcastStream().listen((data) {
onEvent(data);
});
}
///实名认证
static Future<void> verify(String certifyId) async {
await _channel.invokeMethod("verify", certifyId);
}
///获取本机参数
static Future<String> getMetaInfos() async {
return await _channel.invokeMethod("getMetaInfos");
}
}
