通过FCM发送自定义推iOS和Android

Question

我需要在基于Firebase的iOS和Android上发送推送消息。不过，此消息必须是数据类型。我认为，APNS配置部分存在问题 例如：

    {
  "to": "dnsX2bJq4dpEUwxuT9qWs-8kZ...", //FCM's token
  "data": {
    "title": "Last Message",
    "body": {
      "auction": null,
      "chat": {
        "last_message": "who is this ?",
        "last_message_date": "2018-12-13 12:56:01",
        "companion": "1",
        "companion_username": "admin"
      }
    }
  },
  "aps": {
        "content-available" : 1,
        "priority": "high"
  }
}

感谢您的回答！
