Flutter - firebase FCM 消息根本不适用于 Testflight 发布版本 [英] Flutter - firebase FCM messages not working on Testflight release builds at all

问题描述

前言:

我的应用是基于 Flutter 的 - 但需要实现本机代码才能使 FCM 消息正常工作，请参阅下文了解更多详情

My App is Flutter based - but native code implementation is required to get FCM messages working, see below for more details

GitHub 问题 #154供参考.

我无法在 iOS 上获取 FCM 通知，特别是在我发布到 Testflight 的应用上.我已经被这个问题困住了一个星期，完全不知道如何继续.

I'm having immense trouble getting FCM notifications working on iOS, specifically on my app published to Testflight. I have been stuck on this problem for a week and have absolutely no idea how to proceed.

问题

使用 Xcode/Android Studio 在我的设备上使用调试/发布版本在本地运行时，会在后台、前台等接收通知.将完全相同的应用程序上传到 Testflight 时，而不是单个通知将通过 FCM 发送.

When running locally using debug/release builds on my devices using Xcode/Android Studio, notifications are received in the background, foreground, etc. When uploading the exact same app to Testflight, not a single notification will come through via FCM.

这很重要，因为 FCM 提供 VoIP 通知，但在 Testflight 上没有收到这些通知，这非常令人沮丧

问题&解决方案?

我发现了 2 个问题(此处 & 这里)，两者似乎都表明这是一个 APNS 证书问题(APNS -> Firebase).我重新创建了我的证书并将其添加到 Firebase 控制台(对所有证书生成操作使用相同的 .csr 文件)

There are 2 questions I found (here & here), both seemed to indicate it is a APNS certificate problem (APNS -> Firebase). I have recreated my certificate and added it to the Firebase console (using the same .csr file for all certificate generating operations)

设置/配置:

• APNS密钥生成&添加到 Firebase

• APNS Key generated & added to Firebase

能力:

尝试过:

<key>FirebaseAppDelegateProxyEnabled</key>
<string>NO</string>

与:

<key>FirebaseAppDelegateProxyEnabled</key>
<string>0</string>

并带有:

<key>FirebaseAppDelegateProxyEnabled</key>
<boolean>false</boolean>

• 背景模式:

    <key>UIBackgroundModes</key>
    <array>
        <string>audio</string>
        <string>bluetooth-central</string>
        <string>external-accessory</string>
        <string>fetch</string>
        <string>location</string>
        <string>processing</string>
        <string>remote-notification</string>

测试:

测试是在 2 部实体 iPhone(6 和 8)上完成的.在使用(调试和发布)模式直接从 Mac(Android Studio 和 XCode)构建时，两者都与 Firebase FCM 一起使用.从 TestFlight 下载相同的文件时，两者都不起作用.

Testing is done on 2 physical iPhones (6s & 8). Both work with Firebase FCM when building directly from Mac (Android Studio & XCode) using (debug & release) modes. Neither works when downloading the same from TestFlight.

如果有人能提供有关错误配置、设置错误或缺少/不正确的 Swift 代码，或者仅仅是错误或遗漏的见解，我们将不胜感激.

If any can provide insight into a misconfiguration, an error in setup or missing/incorrect Swift code, or simply a mistake or omission, it would be much appreciated.

推荐答案

前言:是我的问题.

TL;DR仅将 CubeEnvironment 的 1 个引用更改为 PRODUCTION.

TL;DR changed only 1 reference of CubeEnvironment to PRODUCTION.

有多个位置可以更改CubeEnvironment:

• push_notifications_manager.dart#111
• push_notifications_manager.dart#111
• call_manager.dart#111

使用建议，最好将其添加到CallManagerService"的init() 方法中:

Suggestion to use, even better to add this in your "CallManagerService"'s init() method:

    bool isProduction = bool.fromEnvironment('dart.vm.product');
    parameters.environment = isProduction ? CubeEnvironment.PRODUCTION : CubeEnvironment.DEVELOPMENT;

---

调试(过程):调试过程(对 Swift 和 XCode 有点陌生)本来可以更好.我考虑了各种配置文件、aps-environment 设置等.

---

Debugging (process): The debugging process (being somewhat unfamiliar with Swift & XCode) could have been better. I considered various provisioning profiles, aps-environment settings, etc.

由于该问题仅发生在 Testflight，它使调试更具挑战性和耗时，因为上传调试版本有其自身的一系列问题

Since the issue only occurred on Testflight, it made debugging alot more challenging and time consuming as uploading a debug build had its own set of issues

最后我添加了一堆日志，其中最重要的是 CB-SDK 调试入口(收到通知时):

Finally I added a bunch of logging, the one that was crucial was the CB-SDK debug entry (when a notification is received):

[
  {
    "subscription": {
      "id": sub id,
      "_id": "insert sub id",
      "user_id": cube_user_id,
      "bundle_identifier": "insert bundle id",
      "client_identification_sequence": "insert client id",
      "notification_channel_id": 6,
      "udid": "insert-uuid",
      "platform_id": 1,
      "environment": "development",
      "notification_channel": {
        "name": "apns_voip"
      },
      "device": {
        "udid": "insert-uuid",
        "platform": {
          "name": "ios"
        }
      }
    }
  }
]

特别是以下条目.

environment": "development

这是因为 APS 使用了 2 个不同的推送通知环境，每个环境都有自己的证书(证书被分配给推送通知可以来自的唯一 URL).这个，aps-environment 设置为 'production(在开始上传之前查看上传存档屏幕)但我正在接收 development 环境通知 - 需要修复.

This is due to APS used 2 different push notification environments, each with its own certificates (certificate is assigned to unique URL's where push notifications can come from). This, aps-environment is set to 'production (see on upload Archive screen right before you start uploading) but I'm receiving development environment notifications - that needed fixing.

查看我的代码，我终于找到了问题(并修复了上面提到的问题).

Reviewing my code, I finally found the issue (and fix mentioned above).
