android - Android Firebase CloudMessaging 在应用程序关闭时不加载 URL 它在单击时加载默认页面

问题描述

我正在使用 FCM 并向 Android 发送推送消息，当应用程序打开并收到推送消息时，URL 意图现在可以通过 TAG 字符串发送。当APP关闭并收到推送消息时，它会加载默认页面。

使用通知的要点：区域是我可以使用channel_id。如果我在 data: JSON 中发送此信息，则它不再侦听 channel_id 但无论应用程序打开还是关闭，推送消息都会打开正确的 URL。

希望我们在 FCM 领域有一些专业人士，并且可以看到我的陷阱。谢谢！

我的 Firebase 消息服务

        protected String title;
        protected String body;
        protected String tag;

    @Override
    public void onNewToken(String token) {
        Log.d(TAG, "Refreshed token: " + token);
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);

        if (remoteMessage.getData().isEmpty()) {
            showNotification(remoteMessage.getNotification().getTitle(),remoteMessage.getNotification().getBody(),remoteMessage.getNotification().getTag());
        } else
            showNotification(remoteMessage.getData());

    }

    private void showNotification(Map<String, String> data) {

        String title = data.get("title");

我的 JSON 发送到 FCM HTTP v1

{
  "message": {
    "token": "dWdgiBqeZCM:APA91bEcufQdXdntHM8uN7PiqTEN2n_CxBF-lbqtC3yFJyF1p8c5qUzf5AfAa33XtQ30bOZxUD1423ia9i071rYvKh8MMGhEhG_DMeQ7EYTIryHoFILlGoTPOuLjdLy-8hqbYdE-MvgF",
    "android": {
      "notification": {
        "title": "Test Title!",
        "body": "Test Body!",
        "channel_id": "1",
        "tag": "https://example.com/"
      }
    }
  }
}

解决方案

您FCM的 Json 包含通知标签，这就是onMessageReceived应用关闭时不调用的原因。所以删除这个通知标签

 "notification": {
    "title": "Test Title!",
    "body": "Test Body!",
    "channel_id": "1",
    "tag": "https://example.com/"
  }

使用data标签而不是notification像这样

 "data": {
    "title": "Test Title!",
    "body": "Test Body!",
    "channel_id": "1",
    "tag": "https://example.com/"
   }

并由此获取数据字段remoteMessage.getData()
