解析到Firebase增强的推送通知

Question

I'm migrating Parse to Firebase and I'm having trouble with the enhanced push notification.

Parse data (iOS side) was like:

{"ast":
  {"alert": {
    {"body": "body_test",
     "title": "title_test",
     "description": "description",
     "endpoint-proposal": "https://.."
     "launch-image": "https://..."
  },
  "sound": "chime",
  ... 
}

Working with Firebase API the ast tag is the ['notification']['body'] .

If I send

['notification']['body'] = 'Hello' 

It works perfectly and generate the following push:

{"ast":
  {"alert": "Hello"}
}...

So, here the problem, I need to send a dictionary in that tag (alert) and I cannot do that because firebase set the value as string.

Example in python:

alert = dict()
alert['title'] = 'title'
alert['description'] = 'description'
alert['endpoint-proposal'] = 'https://..'
alert['launch-image'] = 'https://..'

fcm_payload['notification']['body'] = alert 

send_push()

And in the iOS side I get:

[AnyHashable("gcm.message_id"): 0:123456789,
 AnyHashable("aps"): {
    alert = "{\"body\": \"body\",
              \"launch-image\": \"https://...\",
              \"endpoint-proposal\": \"https://...\",
              \"description\": \"description\",
              \"title\": \"title\"}";
}]

Always as string :S

Is there any way to send that alert as dict?

Answer 1

The notification body parameter will always be treated by FCM as a String . It's just the behavior. What you'll have to do is make use of the data payload and put in your custom key-value pairs:

On iOS, if the message is sent via APNS, it represents the custom data fields. If it is sent via FCM connection server, it would be represented as key value dictionary in AppDelegate application:didReceiveRemoteNotification: .

More details can be seen in this Receiving Messages in iOS doc. I think for your case, you just have to use the notification and data parameters together in your payload.

json.loads（）应该给你一个字典。
