昨晚我在我的应用程序中使用 FCM 测试推送通知，它崩溃了（几天前它还在工作）。我使用 firebase 控制台中的通知菜单对其进行测试。

我进一步调查通知有效负载格式已更改，并且不包括Apple Documentation中的那种 iOS 格式。

我重新检查了我的 APNs 证书，开发证书不见了，我尝试重新上传证书，它得到了类似这样的错误。

我向 firebase 团队提交了反馈，并说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，但格式还是一样的。

这是我得到的有效载荷（来自 Swift Print 函数）

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

而这个payload使得iOS不会显示推送通知。

并基于此适用于 iOS 的 FCM 文档

以下代码将在通知到来时使应用程序崩溃

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
  • 我还提交了另一个反馈，但 Firebase 团队尚未回复

我错过了什么吗？

编辑：

就像我上面说的，它在几天前就可以工作了，当这个问题出现时它就崩溃了。

具体来说，这一行会使应用程序崩溃，我怀疑这是因为有效负载格式发生了变化（缺少 aps 有效负载）。

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

该代码在删除它（并在上面生成）时运行良好，但我仍然没有得到 aps 有效负载格式，因此当应用程序在后台时，通知永远不会弹出。当应用程序在前台时，我的通知处理程序也将无法工作。

编辑 2：

我已经在我的 AppDelegate 中注册了通知

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

我知道这一点并且已经启用了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，但我仍然得到了像这样的相同有效负载格式

%@ [notification: {
    badge = 2;
    body = "Test Message";
    e = 1;
    sound = default;
    sound2 = default;
    title = Test;
}, collapse_key: com.xxx, from: 717xxxxxx]

我的 FCM Firebase 控制台设置如下所示

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];
}

之后，fcm 开始发送带有为 iOS 正确格式化的有效负载的推送。

当然适用于生产环境FIRInstanceIDAPNSTokenTypeProd

您正在打印的“有效负载”对我来说很合适。但是，请注意，这不是 APN 有效负载。它实际上是一个用户信息字典。如果我理解您的问题，您似乎担心该"aps"字段丢失。您不会在用户信息字典中看到该字段。

您是在真实设备上还是在模拟器中运行它？请记住，模拟器无法显示远程通知，并且在真实设备上，应用程序需要在后台显示通知。

尝试发送本地通知（安排 30 秒时间）：

localNotif.fireDate = [[NSDate date] dateByAddingTimeInterval:30];

然后按home键等待。

您提供的“有效负载”（大概）是由didReceiveRemoteNotification方法的最后一行产生的，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。

我认为其他东西正在使您的应用程序崩溃。你看过系统日志吗？（如果您使用的是模拟器，请转到 Debug>Open System Log）。

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

我正在调查为什么您的 gcm.message_id 为空，请给我几天时间。

当应用程序在后台时没有收到通知，请确保您注册远程通知，如快速入门示例中所示（请参阅 didFinishLaunchingWithOptions）：https ://github.com/firebase/quickstart-ios/blob/master /messaging/FCMSwift/AppDelegate.swift

此外，请确保在 Xcode 中您已将功能设置为允许处理后台通知。

这里同样的问题。此外，使用控制台发送时，带有键“aps”的 Firebase 消息似乎未传递。必须是 Firebase 的一些错误，用于更改有效负载格式。

关于在后台模式下获取 Firebase 通知，在这种情况下，我认为 iOS 将无法识别有效负载格式 -> 根本没有通知。要在后台从 Firebase 读取消息，请不要在切换到后台模式时调用FIRMessaging.messaging().disconnect() 。然后你应该得到你的消息并用你自己的句柄处理它（仍然没有系统通知）。

我浏览了苹果的开发者论坛，似乎它didRegisterForRemoteNotificationsWithDeviceToken不能在沙盒模式下工作，只能在生产环境下工作。didRegisterForRemoteNotificationsWithDeviceToken是我向 firebase 注册 deviceToken 的地方。由于这没有发生，Firebase 正在发送带有notification密钥的有效负载，因为它不知道该设备是 Apple。今天苹果解决了这个问题，现在我可以发送通知了。

我遇到了同样的问题，我添加了“高”优先级，它对我有用！

{
    "collapse_key" :"com.xxx.xxx",
    to: "xxx",
    priority : "high",
    notification :{..}
}
