说明问题:
我现在已经尝试让firebase_messaging工作近一个星期。 我成功地建立了一个旧的Xcode APNS应用程序,该应用程序在生成所有新证书等后可以正常工作。 但是用firebase_messaging我根本没有任何通知。 我什至可以重新创建一个新的flutter,firebase和appstoreconnect项目/应用程序。 但是我根本没有从firebase收到任何通知,无论是用本机Xcode还是flutter实现。 如果我订阅一个尚不存在的主题,则说明该主题正在创建; Android和iOS上的Analytics(分析)上的通知以及iOS和Android上的InAppMessaging都可以正常工作,因此肯定可以正常工作。
到目前为止我尝试过的是:
代码段以重新创建配置:
重新创建的步骤可能只是下载Firebase Messaging示例项目,或者遵循为本地Xcode或Flutter设置Firebase Messaging的官方文档。重新创建此处列出的示例的基本步骤:
已实现的插件(所有最新版本):
Flutter / Dart(main.dart):
void firebaseCloudMessaging_Listeners() {
if (Platform.isIOS) iOS_Permission();
firebaseMessaging.getToken().then((token){
print(token);
});
firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print('on message $message');
},
onResume: (Map<String, dynamic> message) async {
print('on resume $message');
},
onLaunch: (Map<String, dynamic> message) async {
print('on launch $message');
},
);
}
void iOS_Permission() {
firebaseMessaging.requestNotificationPermissions(
IosNotificationSettings(sound: true, badge: true, alert: true)
);
firebaseMessaging.onIosSettingsRegistered
.listen((IosNotificationSettings settings)
{
print("Settings registered: $settings");
});
}
void subscribeToFB() {
firebaseMessaging.subscribeToTopic('vertretungsplanSandbox');
print("--- SUBSCRIBED ---");
}
void unsubscribeFromFB() {
firebaseMessaging.unsubscribeFromTopic('vertretungsplanSandbox');
print("--- UNSUBSCRIBED ---");
}

IDE(Xcode / VS Code @ macOS HS)不返回任何错误;调试日志中也没有错误。该应用程序报告运行正常,但消息没有通过。
有人可以帮我吗?谢谢!

解决方法是仅删除建议的.p8密钥文件(从Firebase控制台>项目设置>云消息系统中),而放入APNS开发和发行证书中。
