Firebase云消息传递通知不发送iOS有效内容格式

Bag*_*ono 12 ios swift firebase-cloud-messaging firebase-notifications

昨晚我在我的应用程序中使用FCM测试推送通知,它已经崩溃了(几天前工作了).我使用firebase控制台中的通知菜单测试它.

我进一步调查通知有效载荷格式已更改,并且不包括Apple文档中的iOS格式.

我重新检查我的APNs证书和开发一个已经不见了,我尝试重新上传证书,它得到类似这样的错误.

我向firebase团队提交了一份反馈,并表示这是他们最终的问题.(注意:我还在上面的链接中发布了firebase团队的回复).我的Dev APNs证书又回来了,但格式仍然相同.

这是我得到的有效载荷(来自Swift Print功能)

{
    "collapse_key" = "com.xxx.xxx";
    from = xxx;
    notification =     {
        badge = 3;
        body = "Firebase console";
        e = 1;
        title = Test;
    };
}

而这个有效载荷使iOS不会显示推送通知.

并基于此iOS的FCM文档

通知到来时,以下代码将使应用程序崩溃

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
  // If you are receiving a notification message while your app is in the background,
  // this callback will not be fired till the user taps on the notification launching the application.
  // TODO: Handle data of notification

  // Print message ID.
  print("Message ID: \(userInfo["gcm.message_id"]!)")

  // Print full message.
  print("%@", userInfo)
}

  • 我已经尝试重新上传我的Dev APNs证书,但仍然出错
  • 我还提交了另一份反馈,但Firebase小组尚未回复

我错过了什么吗？

编辑:

就像我上面所说的那样,几天前就可以工作了,当这个问题出现时就会崩溃.

特别是这一行将使应用程序崩溃,我怀疑它是因为有效载荷格式发生了变化(缺少aps有效载荷).

print("Message ID: \(userInfo["gcm.message_id"]!)")

删除它(并在上面生成)时代码运行良好,但我仍然没有获得aps有效负载格式,因此当应用程序在后台时,通知将永远不会弹出.当前景中的应用程序时,我的通知处理程序也无法运行.

编辑2:

我已经在AppDelegate中注册了通知

let setting = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge] , categories: nil)
    application.registerUserNotificationSettings(setting)
    application.registerForRemoteNotifications()

我知道这一点,并已启用推送通知和远程通知后台模式.

我再次尝试从firebase控制台推送通知,但我仍然得到了相同的有效负载格式

%@ [notification: {
    badge = 2;
    body = "Test Message";
    e = 1;
    sound = default;
    sound2 = default;
    title = Test;

我有同样的问题

关于 fcm 指南的这一部分：https ://firebase.google.com/docs/cloud-messaging/ios/client#swizzling_disabled_receive_messages_through_the_messaging_apns_interface

我解决了添加问题 setAPNSToken:type:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];
}
Run Code Online (Sandbox Code Playgroud)

在那之后，fcm 开始发送带有为 iOS 正确格式化的有效负载的推送。

当然用于生产环境使用 FIRInstanceIDAPNSTokenTypeProd

您提供的“有效负载”（大概）是由该didReceiveRemoteNotification方法的最后一行生成的，即print("%@", userInfo).

您声称上面的代码使应用程序崩溃，这与成功打印到日志的代码相矛盾。

我认为其他原因导致您的应用程序崩溃。你看过系统日志吗？（如果您使用的是模拟器，请转到“调试”>“打开系统日志”）。

我建议运行 Firebase 演示应用程序 ( pod try Firebase)，以说服自己它正在按您的预期工作。
