GCM推送通知消息在数据字典之外-Java 学习之路

有没有办法在向GCM发送通知时检索设备上的密钥“消息” .

{ "collapse_key" : "score",
     "data" : { "k1" : "v1" },
     "message" : "Hello World!",
     "registration_ids" : [ "DEVICE_REGISTRATION_ID_GOES_HERE" ]
   }

从intent.getExtras（），我能够收到以下键“ collapse_key ", " from ", " k1 " and their corresponding values as well. However I do not get key " message ". If I do not add anything in the " data " dictionary, I still get push notification without " k1 ”（正如预期的那样） .

推送到GCM不会导致错误 . GCM是否删除“ data ”字典中未提及的密钥？

是的，你拥有它的方式是行不通的 . 您要添加的任何内容，使其成为数据对象的一部分：

{
    "collapse_key": "score",
    "data": {
        "k1": "v1",
        "message": "Hello World!"
    },
    "registration_ids": [
        "DEVICE_REGISTRATION_ID_GOES_HERE"
    ]
}
