我目前正在努力通过 Parse 为带有 GCM 的 Android App 实现推送通知。这是我所拥有的和有效的：我按照 GitHub 项目推送通知中的自述步骤 我修改了 registrationHandler 以注册 deviceToken：

var req = {
  method: ‘POST’,
  url: ‘api.parse.com/1/installations’,
  headers: {
    ‘X-Parse-Application-Id’: ‘xxx’,
    ‘X-Parse-REST-API-Key’: ‘xxx’,
    ‘Content-Type’: ‘application/json’
  },
  data: {
    ‘deviceType’: ‘android’,
    ‘pushType’: ‘gcm’,
    ‘deviceToken’: deviceToken,
    ‘GCMSenderId’: senderID
  }
}
$http(req).success(function(){
  alert('Successfully registered');
}).error(function(){
  alert('Error with Registration');
});

我在构建配置中启用了推送通知，并且能够构建和安装 apk。在解析核心模块中，我可以看到已注册的设备。我已将 Google 项目 ID 和 API 密钥添加到 Parse。如果我从安装表中复制 deviceToken 并将其与此 Ruby 脚本一起使用，我会立即收到通知。

require 'rubygems'
require 'pushmeup'

APPLICATION_API_KEY = "API_KEY_GOES_HERE"
DEVICE_REGISTRATION_ID = "REGISTRATION_ID_GOES_HERE"

GCM.host = 'https://android.googleapis.com/gcm/send'
GCM.format = :json
GCM.key = APPLICATION_API_KEY
destination = [DEVICE_REGISTRATION_ID]
data = {:message => "PhoneGap Build rocks!", :msgcnt => "1", :soundname => "beep.wav"}

puts GCM.send_notification( destination, data)

但是如果我从 Parse 发布通知，我不会收到通知。我错过了什么？

编辑 1：同时我查看了 LogCat，发现消息实际上已传递到我的设备，但消息处理过程中出现了问题：

            at Object.parse (native)

编辑 2：好的，我调试了传入的推送通知，我从这两种方法收到的 JSON 是不同的。所以我认为 Cordova 的 PushPlugin 无法处理 Parse.com 的 JSON

来自红宝石的消息：
