GCM Error=MissingRegistration sending messages via JSON

Question

I\'m testing push GCM via Fiddler

Headers:

User-Agent: Fiddler
Authorization: key=AIzaSyAkXfcuLLCZ-5n18wwO6XeJ13g-z9ja
Host: android.googleapis.com
C         


        

Answer 1

For the new cloud Message, when you want to send a dwonstream message from the server, you need to use "to" to declaim the target registration id.

like below :

https://gcm-http.googleapis.com/gcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{ "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to" : "APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx..."
}
