GCM未在通知中使用JSON有效负载中的数据

Question

I am sending the following JSON through GCM (Google Cloud Messaging) but I have not been able to get the right response data through the Client. I get a push notification response, but the title is the App's name, and the texts reads: "message" so I can't display my notification properly.

Here is the JSON that I am trying to send:

{  
  "to": "somekey",
  "notification": {  
      "body":"Test",
      "title":"Test"
  },
  "data": null
}

Answer 1

I think that your problem is on the key-values of the payload of your message.

As you can see at GCM Server documentation , the payload can be set using two different keys:

• data : This parameter specifies the key-value pairs of the message's payload.
• notification : This parameter specifies the key-value pairs of the notification payload.

You should use the data key and set inside the payload of the notification. Once send, you can print the result of the notification received and see that there are the right payload inside the data key.

Your message should be like the following JSON data:

{
  "registration_ids" => "some_target_device_id",
  "data": {
      "title": "My title",
      "message": "This is the message!",
  }
}

Authorization: key= AIz......#GCM project key

{ "data": {
              "title": "Summer Offer.",
              "message": "Click to visit the offer."
          },
              "to" : "Device Token"
}
