示例代码

以下是一个完整的示例代码,展示如何使用secure_control_protocol插件进行设备控制。

import 'package:secure_control_protocol/secure_control_protocol.dart';

void main() async {
  // 初始化SCP客户端
  final client = SCPClient();

  // 发现设备
  await client.discover(ipAddress: '192.168.1.0', mask: 24);

  // 获取已发现的设备列表
  List<Device> discoveredDevices = client.getDiscoveredDevices();
  print('Discovered Devices: $discoveredDevices');

  // 控制特定设备
  if (discoveredDevices.isNotEmpty) {
    Device firstDevice = discoveredDevices.first;
    String command = 'turnOn';
    await client.control(deviceId: firstDevice.id, command: command);
    print('Controlled Device ID: ${firstDevice.id}, Command: $command');
  } else {
    print('No devices discovered.');
  }
}

secure_control_protocol 是一个用于在 Flutter 应用中实现安全控制协议的插件。它可以帮助你在应用中安全地管理设备控制、数据传输等操作。以下是如何在 Flutter 项目中使用 secure_control_protocol 插件的基本步骤。

1. 添加依赖

首先,你需要在 pubspec.yaml 文件中添加 secure_control_protocol 插件的依赖。

dependencies:
  flutter:
    sdk: flutter
  secure_control_protocol: ^0.0.1  # 请使用最新版本

然后运行 flutter pub get 来获取依赖。

2. 导入插件

在你的 Dart 文件中导入 secure_control_protocol 插件。

import 'package:secure_control_protocol/secure_control_protocol.dart';

3. 初始化插件

在使用插件之前,你需要初始化它。通常,你可以在 main 函数或 initState 方法中进行初始化。

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 初始化 SecureControlProtocol
  await SecureControlProtocol.initialize();
  
  runApp(MyApp());
}

4. 配置安全控制协议

你可以根据需要配置安全控制协议。例如,设置密钥、加密算法等。

SecureControlProtocol.configure(
  encryptionKey: 'your_encryption_key',  // 设置加密密钥
  algorithm: 'AES-256-CBC',              // 设置加密算法
);

5. 使用插件进行安全操作

你可以使用 secure_control_protocol 插件进行安全的数据传输、设备控制等操作。例如,发送加密的控制命令。

void sendControlCommand() async {
  String command = 'turn_on';
  String encryptedCommand = await SecureControlProtocol.encrypt(command);
  
  // 发送加密的命令到设备
  // 例如,使用 HTTP 请求或其他通信方式发送 encryptedCommand
}

6. 解密和验证

在接收到加密的响应后,你可以使用插件进行解密和验证。

void receiveResponse(String encryptedResponse) async {
  String decryptedResponse = await SecureControlProtocol.decrypt(encryptedResponse);
  
  // 处理解密后的响应
  print('Decrypted Response: $decryptedResponse');
}

7. 错误处理

在使用插件时,可能会遇到各种错误,例如加密失败、解密失败等。你可以使用 try-catch 块来捕获和处理这些错误。

try {
  String encryptedCommand = await SecureControlProtocol.encrypt(command);
} catch (e) {
  print('Encryption failed: $e');
}

8. 清理资源

在应用退出时,你可能需要清理插件占用的资源。

void dispose() {
  SecureControlProtocol.dispose();
  super.dispose();
}
