Flutter苹果推送通知插件flutter_apns_x的使用

当然，以下是如何在Flutter项目中使用flutter_apns_x插件来配置苹果推送通知的示例代码。这个插件允许你通过Apple Push Notification Service (APNs)发送推送通知给iOS设备。

首先，确保你已经添加了flutter_apns_x到你的pubspec.yaml文件中：

dependencies:
  flutter:
    sdk: flutter
  flutter_apns_x: ^x.x.x  # 替换为最新版本号

然后运行flutter pub get来安装依赖。

iOS 配置

1. 配置Info.plist

   确保你的Info.plist文件中包含必要的推送通知权限请求：

   <key>UIBackgroundModes</key>
   <array>
       <string>remote-notification</string>
   </array>
   <key>UIApplicationSupportsIndirectInputEvents</key>
   <true/>
   <key>NSAppTransportSecurity</key>
   <dict>
       <key>NSAllowsArbitraryLoads</key>
       <true/>
   </dict>
   <key>UNNotificationBreakthroughPriority</key>
   <integer>1</integer>
   

2. 配置AppDelegate.swift

   在AppDelegate.swift中，确保你已经注册了推送通知，并处理了APNs的回调：

   import UIKit
   import UserNotifications
   import Flutter
   import flutter_apns_x
   
   [@UIApplicationMain](/user/UIApplicationMain)
   [@objc](/user/objc) class AppDelegate: FlutterAppDelegate {
       override func application(
           _ application: UIApplication,
           didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
       ) -> Bool {
           GeneratedPluginRegistrant.register(with: self)
   
           // 注册推送通知
           UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
               if granted {
                   DispatchQueue.main.async {
                       application.registerForRemoteNotifications()
                   }
               }
           }
   
           return super.application(application, didFinishLaunchingWithOptions: launchOptions)
       }
   
       override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
           // 将deviceToken发送到你的服务器以保存
           let flutterEngine = (UIApplication.shared.delegate as? FlutterAppDelegate)?.window??.rootViewController as? FlutterEngine
           let channel = FlutterMethodChannel(name: "your_channel_name", binaryMessenger: flutterEngine!.binaryMessenger)
           channel.invokeMethod("registerDeviceToken", arguments: deviceToken.hexString)
       }
   
       override func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
           print("Failed to register for remote notifications: \(error.localizedDescription)")
       }
   
       override func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
           // 处理接收到的推送通知
           print("Received remote notification: \(userInfo)")
           completionHandler(.newData)
       }
   }
   
   // 将Data类型转换为hex字符串的扩展
   extension Data {
       var hexString: String {
           return reduce("", { $0 + String(format: "%02x", $1) })
       }
   }
   

3. Flutter端代码

   在你的Flutter项目中，你可以使用flutter_apns_x插件来发送推送通知。下面是一个简单的示例：

   import 'package:flutter/material.dart';
   import 'package:flutter_apns_x/flutter_apns_x.dart';
   
   void main() {
     runApp(MyApp());
   }
   
   class MyApp extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         home: Scaffold(
           appBar: AppBar(
             title: Text('Flutter APNs X Example'),
           ),
           body: Center(
             child: ElevatedButton(
               onPressed: () async {
                 // 发送推送通知的示例
                 String deviceToken = "your_device_token_here";  // 替换为实际的device token
   
                 var payload = APNSPayload(
                   aps: APS(
                     alert: Alert(title: "Hello", body: "This is a test notification!"),
                     sound: "default",
                     badge: 1,
                   ),
                   customData: {
                     "key1": "value1",
                     "key2": "value2"
                   },
                 );
   
                 var apnsClient = APNSClient(
                   teamId: "your_team_id",
                   keyId: "your_key_id",
                   keyPath: "path/to/your/AuthKey_your_key_id.p8",  // 替换为你的.p8文件路径
                 );
   
                 try {
                   await apnsClient.sendNotification(deviceToken, payload);
                   print("Notification sent successfully");
                 } catch (e) {
                   print("Failed to send notification: $e");
                 }
               },
               child: Text('Send Notification'),
             ),
           ),
         ),
       );
     }
   }
   
   class APS {
     Alert? alert;
     String? sound;
     int? badge;
   
     APS({this.alert, this.sound, this.badge});
   }
   
   class Alert {
     String? title;
     String? body;
   
     Alert({this.title, this.body});
   }
   
   class APNSPayload {
     APS? aps;
     Map<String, dynamic>? customData;
   
     APNSPayload({this.aps, this.customData});
   }
   
   class APNSClient {
     String teamId;
     String keyId;
     String keyPath;
   
     APNSClient({required this.teamId, required this.keyId, required this.keyPath});
   
     Future<void> sendNotification(String deviceToken, APNSPayload payload) async {
       // 发送通知的逻辑，这里需要实际的HTTP/2请求代码
       // 使用Dart的http2或类似库来发送请求
       // 注意：这只是一个示例，你需要实现完整的发送逻辑
     }
   }
   

注意：

• APNSClient的sendNotification方法需要实现完整的HTTP/2请求来发送APNs通知。这通常涉及读取.p8文件，使用它创建JWT token，并发送HTTP/2请求到APNs服务器。由于这涉及到复杂的网络和加密逻辑，建议使用现有的Dart库如http2或dart:http（结合适当的加密库）来实现。
• 示例中的APNSClient和sendNotification方法仅提供了框架，你需要根据APNs文档和库文档来完成实际的实现。
• 确保你的.p8文件路径和权限正确设置。
• 替换示例代码中的占位符（如your_team_id, your_key_id, path/to/your/AuthKey_your_key_id.p8）为实际的值。

希望这个示例能帮助你在Flutter项目中集成和使用flutter_apns_x插件。
